How Enphase Energy Makes its Money: Revenue Breakdown

Key Takeaways

• Enphase Energy generated $1.63 billion in total revenue in 2024 — down -28.8% from a 2023 peak of $2.29B, the sharpest downturn in the company’s history
• The collapse was driven by high interest rates (expensive solar financing), California NEM 3.0 (reduced solar export compensation), and distributor inventory destocking
• IQ Battery revenue grew +60% to $0.40B — a bright spot and growing share of total revenue
• Gross margin fell from 45.4% to 39.9%; operating margin from 18.3% to 1.8% — largely a volume deleveraging problem, not structural
• Enphase remains free cash flow positive (~$300M) despite the downturn — the asset-light model held up
• U.S. manufacturing expansion qualifies Enphase for IRA Section 45X production tax credits — a structural margin tailwind as volumes recover
• The competitive landscape improved: SolarEdge (primary rival) has faced severe financial difficulties since 2023, creating a market share opportunity for Enphase

How Does Enphase Energy Make its Money?

Enphase Energy is the world’s leading manufacturer of residential solar microinverters — the devices that convert the DC electricity produced by solar panels into AC electricity for home use. The company’s products sit at the intersection of solar energy hardware, power electronics, and energy management software.

Enphase’s business model is straightforward on the surface: it sells hardware (microinverters, batteries, EV chargers) to solar installers and distributors, who bundle Enphase products into residential rooftop solar systems sold to homeowners. But underneath that simple transaction model is a more interesting story about technology differentiation, ecosystem lock-in, and an expanding platform that captures more revenue per home energy installation over time.

The company has expanded well beyond inverters into a full home energy management ecosystem: the IQ8 microinverter (the core product), IQ Battery home storage, IQ EV Charger, and the Enphase Energy App — a software layer that monitors and manages all energy flows in a home. This ecosystem approach increases revenue per installed home and creates switching costs that make customers less likely to adopt competitors’ products for future additions.

The 2024 results tell the story of a company navigating the sharpest industry downturn since the pre-ITC extension slump of 2016. Revenue fell -28.8% from peak as the residential solar market contracted sharply — but Enphase held onto its technology leadership, maintained its gross margin above 39%, stayed free cash flow positive, and watched its primary rival (SolarEdge) face an existential financial crisis. The setup for recovery depends primarily on interest rate direction and policy stability.

Enphase Energy (ENPH) Business Model

Enphase’s business model is best understood as hardware-enabled platform economics in the residential energy market. The initial sale is a hardware transaction — a homeowner’s installer buys Enphase microinverters and batteries. But Enphase’s strategic goal is to make the Enphase ecosystem the operating system for residential energy, capturing additional revenue and engagement as homeowners add batteries, EV chargers, and future energy products.

The Microinverter: Core Product and Revenue Engine

A microinverter is an electronic device roughly the size of a hardcover book, mounted on the back of each individual solar panel. Its job is to perform maximum power point tracking (MPPT) — continuously optimizing the output of its panel — and convert DC to AC in one step at the panel level.

Why microinverters instead of string inverters?

Traditional residential solar uses a string inverter — one central unit that handles DC-to-AC conversion for the entire array. String systems are cheaper per watt on paper, but have key limitations:

• Shade sensitivity — If one panel in a string is shaded or dirty, the whole string’s output falls to the weakest panel’s level
• Single point of failure — If the string inverter fails, the whole system goes offline
• High-voltage DC wiring — Long runs of high-voltage DC wire on the roof create fire and safety risks
• Monitoring — Limited insight into individual panel performance

Enphase’s microinverter approach eliminates all four limitations: each panel performs independently, any single microinverter failure affects only one panel, there is no high-voltage DC on the roof (safer for firefighters), and the Enphase app shows performance data for each panel individually.

The premium pricing this commands — Enphase microinverters cost more per watt than string inverter systems — is the foundation of Enphase’s gross margin.

IQ8: The Grid-Forming Advantage

The IQ8 microinverter (launched 2022) introduced a capability that no string inverter can match: Sunlight Backup. During a grid outage, the IQ8 can continue generating power directly from solar panels and supplying critical loads — without a battery. This is possible because the IQ8 is a grid-forming inverter that can create its own AC reference signal, rather than depending on the grid’s signal to operate.

This capability has been a meaningful differentiator in markets experiencing grid reliability concerns (Texas, California) and among customers considering solar-plus-storage systems. It also serves as a natural upgrade path: a customer starts with IQ8 solar (which gives them some backup capability), then adds an IQ Battery for full overnight storage and extended backup.

IQ Battery: The Ecosystem Expansion

IQ Battery is Enphase’s home energy storage product — a lithium iron phosphate (LFP) battery system available in multiple capacity configurations. LFP chemistry was specifically chosen for its safety profile (no thermal runaway risk), longer cycle life compared to NMC lithium-ion, and compatibility with daily cycling demanded by self-consumption use cases.

IQ Battery integrates natively with Enphase microinverters and is managed through the same Enphase Energy App that monitors solar production. This native integration is a meaningful advantage over third-party batteries paired with Enphase solar — the system coordinates more efficiently when inverter and battery share a common control architecture.

Battery revenue grew +60% in 2024 to approximately $0.40 billion. Battery attach rates — the percentage of new solar installations that also include a battery — have been rising, driven by:

• NEM 3.0 in California — The revised net metering policy reduces the compensation homeowners receive for solar exported to the grid, making self-consumption (via battery) more economically attractive
• Grid reliability concerns — High-profile outages in California, Texas, and increasingly in other states are driving demand for backup power capability
• Declining battery costs — LFP battery pack costs have fallen significantly, making battery economics more compelling for installers and homeowners

Go-to-Market: Installer and Distributor Channel

Enphase does not sell directly to homeowners. It sells to solar installers (directly) and distributors (who supply installers). This two-tier channel model means:

• Enphase’s actual end customers are the installer community — companies like Sunrun, Freedom Solar, and thousands of independent installers
• Distributors like CED Greentech, BayWa r.e., and similar companies stock Enphase products and supply regional installer networks

The installer relationship is critical. Installers are trained on specific products and build processes around them — a crew that installs Enphase systems daily is reluctant to switch to a different system that requires retraining and new tools. This installer loyalty is a key source of Enphase’s competitive stickiness.

Enphase has invested in installer tools and training programs (the Enphase Installer Network) to deepen these relationships and create barriers to competitive switching.

Software and Services

The Enphase Energy App is the software layer that monitors all Enphase devices in a home, giving homeowners visibility into solar production, battery state of charge, grid import/export, and EV charging. Enphase also offers monitoring services to installers through the Enlighten platform.

Software and services revenue is currently a small portion of total revenue but represents an important long-term opportunity. As Enphase’s installed base grows — millions of homes globally with Enphase hardware — the potential for recurring software services, grid services (virtual power plants), and demand response programs grows.

IRA Section 45X Manufacturing Credits

Enphase made a strategic decision to expand U.S. manufacturing — specifically a facility in Columbia, South Carolina — to qualify for IRA Section 45X production tax credits. Section 45X provides a credit of $0.065 per watt of inverter capacity manufactured in the U.S. For a microinverter rated at, say, 380W, that’s approximately $0.025 per unit.

At Enphase’s scale, this amounts to significant dollar credits that reduce COGS and improve gross margin. The strategic calculus was that domestic manufacturing costs more but the 45X credit more than offsets the cost premium over contract manufacturing in Mexico or Asia.

The durability of 45X credits under future administrations is a policy risk. Enphase has explicitly highlighted this in its risk disclosures.

Enphase Energy Competitors

Enphase’s primary technology competitor is SolarEdge Technologies — a company that uses a different architecture (DC-optimized power optimizers on each panel, feeding into a central string inverter) that achieves some of the same shading tolerance benefits as microinverters at lower cost. SolarEdge dominated the U.S. residential market for several years and competed intensely with Enphase globally.

However, SolarEdge has experienced a severe financial crisis since 2023 — revenue collapsed, the company took hundreds of millions in inventory write-downs, and its stock fell over 90% from peak. SolarEdge’s struggles are Enphase’s opportunity: installers who might have chosen SolarEdge for cost reasons are increasingly defaulting to Enphase as the category’s financially stable, U.S.-supported option.

Tesla Powerwall competes directly with IQ Battery in home energy storage. Tesla’s brand and ecosystem (particularly for Tesla vehicle owners) gives it distribution advantages. However, Enphase’s native integration with its microinverter architecture and its broad installer network are competitive strengths. For a broader look at Tesla’s energy business in context, see Tesla.

Chinese inverter manufacturers — Huawei, Sungrow, Growatt, and others — compete in international markets on price. They are generally not a significant factor in the U.S. (trade policy and security concerns limit their presence) but compete directly with Enphase in Europe, Australia, and emerging markets.

NextEra Energy and other large utilities represent the broader competitive context — distributed solar (Enphase’s end market) competes with centralized utility generation for the marginal electricity dollar. NextEra Energy is the world’s largest renewable energy producer and operator of utility-scale solar and wind — a different but related part of the clean energy transition. Duke Energy and Constellation Energy represent the traditional utility model that residential solar disrupts.

Revenue Breakdown

By Geography

The geographic breakdown reveals that the U.S. — Enphase’s largest market — experienced the sharpest decline, primarily driven by NEM 3.0 in California (Enphase’s single most important market within the U.S.) and rate-sensitive financing markets broadly. Europe declined less severely; Enphase has been gaining share in Germany, France, and the Netherlands where energy prices remain elevated and policy support for distributed solar is strong.

Microinverters — 72% of Revenue

Microinverter sales are the core business and the primary driver of the 2024 revenue decline. Unit shipments fell sharply as installers and distributors drew down excess inventory built up during the 2022–2023 solar installation boom. This inventory destocking effect is important to understand: Enphase’s reported revenue fell more than actual underlying end-customer demand because distributors stopped ordering from Enphase while they sold through their stockpile.

Enphase’s current microinverter product line centers on the IQ8 Series:

• IQ8A — Standard residential microinverter, 384W AC output
• IQ8M — For high-powered panels up to 550W DC input
• IQ8H — Optimized for commercial rooftop applications
• IQ8P-3P — Three-phase commercial version for European and commercial markets

The IQ8 platform is the most technically advanced residential microinverter on the market, with the Sunlight Backup grid-forming capability as the key differentiator. Enphase has announced the IQ9 platform — which will support even higher-wattage next-generation panels — as part of its product roadmap.

Average selling price (ASP) per microinverter declined modestly in 2024 as Enphase offered pricing accommodations to win incremental orders in a weak demand environment. Recovering volume is the primary path to gross margin restoration — the fixed cost base was maintained through the downturn in anticipation of recovery.

IQ Battery — 25% of Revenue

IQ Battery was the standout performer in 2024, growing +60% to approximately $0.40 billion as battery attach rates increased and the product gained market share against Tesla Powerwall.

IQ Battery product lineup:

• IQ Battery 5P — 5 kWh capacity, designed for stacking (up to 4 units for 20 kWh)
• IQ Battery 10T — 10.28 kWh, Enphase’s flagship home storage unit
• IQ Battery 3T — Entry-level 3.84 kWh unit for cost-sensitive markets

The LFP chemistry choice — lithium iron phosphate rather than the NMC chemistry used by some competitors — provides:

• Safety — LFP does not undergo thermal runaway, eliminating fire risk that has been associated with NMC battery incidents
• Cycle life — LFP typically handles 3,000–4,000+ cycles versus 1,000–2,000 for NMC, critical for daily charging systems
• Degradation — LFP retains capacity better over time

California’s NEM 3.0 policy, which took effect in April 2023, is a structural long-term tailwind for battery attach rates. Under NEM 3.0, the compensation for solar energy exported to the grid was reduced by approximately 75%. This makes storing solar in a battery (and using it at night) far more economically valuable than exporting. Installers and homeowners increasingly see battery as essential, not optional, under the new regime.

Enphase Energy (ENPH) Income Statement

Financial data sourced from Enphase Energy SEC Filings.

The income statement shows a textbook operating leverage squeeze: revenue fell -28.8%, but operating expenses were held flat at $0.62B (Enphase chose to invest through the downturn). The result was that a $660M decline in revenue translated into a $390M decline in operating income — the ratio of decline is far larger than the revenue decline alone, because every dollar of lost revenue fell through with no corresponding reduction in fixed costs.

This operating leverage works powerfully in reverse on recovery: as revenue grows back toward $2B+, operating expenses should not grow proportionally, creating substantial margin expansion.

Enphase Energy (ENPH) Key Financial Metrics

Key Metric Observations

Gross margin of 39.9% is still exceptional for a hardware manufacturer. For comparison, most pure hardware companies (consumer electronics, industrial equipment) earn 20–35% gross margins. Enphase’s 39%+ reflects genuine technology differentiation — customers pay a premium for microinverters because they outperform string alternatives in shade tolerance, safety, and monitoring. The decline from 45.4% is primarily a volume story (less manufacturing leverage), not a pricing power story.

Free cash flow of ~$300M despite a -28.8% revenue collapse is the most important metric validating Enphase’s business quality. The asset-light model (contract manufacturing, lean operations) means cash generation does not collapse as sharply as reported income when revenue declines. Enphase used this cash to repurchase shares at prices well below where the stock had traded at peak, a value-accretive capital allocation decision.

Operating expenses held flat at $0.62B was a deliberate choice. Enphase did not cut R&D during the downturn — the IQ9 platform, next-generation batteries, and software capabilities were all funded through the decline. This “invest through the cycle” strategy preserves competitive position and prepares for stronger revenue recovery.

IQ Battery at ~700 MWh of shipments puts Enphase among the top residential battery providers in the U.S. For scale: Tesla Powerwall ships multi-GWh annually globally; 700 MWh is a meaningful but not dominant position. Continued growth in battery attach rates is the most visible path to diversifying revenue away from rate-sensitive microinverter demand.

Is Enphase Energy Profitable?

Yes, barely in 2024. Enphase reported:

• Net income: $0.05 billion (3.1% net margin)
• Operating income: $0.03 billion (1.8% operating margin)
• Gross margin: 39.9%
• Free cash flow: ~$300 million

The contrast with 2023 is stark: net income fell from $0.44B to $0.05B (-88.6%) on a revenue decline of only -28.8%. This mathematical mismatch reflects operating leverage — fixed costs (R&D, SG&A, manufacturing overhead) did not decline when revenue did, so the entire decline fell through to operating income.

The recovery story is the mirror image: as residential solar demand recovers — driven by lower interest rates, post-NEM 3.0 new-normal installation dynamics, and continued growth in battery attach — revenue growth should translate into disproportionately large operating income growth.

Importantly, Enphase did not become unprofitable in the way many hardware companies do in downturns — it did not run negative gross margins, it did not draw down its cash reserves, and it did not cut into product development. It finished 2024 with approximately $1.5B in cash and investments — substantial financial flexibility for a $15B market cap company.

Where Does Enphase Energy Spend its Money?

Cost of Revenue (~$0.98B, 60.1% of revenue)

Enphase’s cost of revenue includes:

• Component costs — Semiconductors (ASICs designed by Enphase), capacitors, transformers, printed circuit boards. Component cost is the largest COGS item.
• Contract manufacturing — Enphase designs its products but outsources most manufacturing to contract manufacturers in Mexico and overseas, plus its new South Carolina facility
• Warranty costs — Enphase provides 25-year warranties on its microinverters, one of the strongest warranty commitments in the industry. Warranty accruals are included in COGS.
• Freight and logistics — Shipping from manufacturing to distributors and installers globally
• IRA 45X credit — Reduces COGS for South Carolina-manufactured units; positively impacts gross margin

Research and Development (~$0.28B, 17% of revenue)

R&D at 17% of revenue is high for a hardware company and reflects Enphase’s self-image as a technology company rather than a commodity manufacturer. R&D spending funds:

• IQ9 microinverter platform — Next-generation inverter for higher-wattage panels
• IQ Battery improvements — Higher capacity, lower cost, improved chemistry
• Semiconductor design — Enphase designs its own ASICs (application-specific integrated circuits) — a key source of competitive advantage and the reason its microinverters can be produced at high quality with consistent performance
• Software and energy management — Enphase Energy App, grid services, VPP (virtual power plant) integration
• EV charger and Powerwall-competing products

Sales and Marketing (~$0.16B, 10% of revenue)

Enphase’s sales and marketing is focused on:

• Installer training and certification — The Enphase Installer Network program trains and certifies installers, creating preference and loyalty
• Homeowner-facing marketing — Digital campaigns building brand awareness among homeowners selecting solar
• Distribution relationships — Maintaining and expanding relationships with solar distributors

General and Administrative (~$0.18B, 11% of revenue)

Standard corporate overhead — executive compensation, legal, finance, and public company compliance.

The 2024 Solar Downturn: What Happened to Enphase

Understanding the context of the 2024 decline is essential for assessing Enphase’s recovery potential.

Factor 1: Interest Rate Shock to Residential Solar Financing The vast majority of residential solar installations are financed — either through solar loans (the homeowner borrows to purchase the system) or through lease/PPA arrangements (a third-party finances the system and sells power to the homeowner at a set rate). When the Fed raised rates from 0% to 5%+, the monthly payment on a typical $25,000–35,000 solar loan increased dramatically. Many homeowners who would have adopted solar at 3% loan rates became uneconomical at 7–8% rates. This single factor probably accounted for the majority of the demand decline.

Factor 2: California NEM 3.0 California represents approximately 30–35% of the U.S. residential solar market and historically a disproportionate share of Enphase’s U.S. revenue. In April 2023, the California Public Utilities Commission implemented NEM 3.0, reducing the compensation for grid-exported solar by approximately 75%. This fundamentally changed the economics of solar in California — standalone solar (without battery) became much less attractive, and many potential installers paused to reassess the new economics. The market contracted sharply in the months following NEM 3.0’s implementation.

Factor 3: Distributor Inventory Destocking During the 2021–2022 supply chain disruptions, solar distributors ordered aggressively to secure product — building months of excess inventory. In 2023–2024, as demand softened, distributors stopped ordering from Enphase while they worked through this stockpile. This created a double-whammy: actual installer demand was bad, but reported Enphase revenue was worse because distributors weren’t ordering even at the lower actual-demand rate.

By late 2024, distributor inventory had normalized — setting up for a more direct read-through of actual installer demand to Enphase’s reported revenue in 2025 and beyond.

Enphase Energy History and Milestones

The near-bankruptcy episode of 2015–2017 is instructive. Enphase was nearly killed by competition from SolarEdge’s lower-cost optimizer system. It survived through radical cost restructuring, the development of its own ASIC semiconductors, and the pivot to a more integrated system architecture. The IQ generation products that emerged from that restructuring were meaningfully better and lower-cost than prior generations — and became the foundation for the current market leadership. That history is relevant context for assessing Enphase’s ability to survive and navigate the current downturn.

Enphase Energy (ENPH): What to Watch

1. Interest Rate Trajectory: The Most Important Macro Variable Residential solar economics are highly rate-sensitive because most systems are financed. Every 100 basis points of rate reduction meaningfully lowers the monthly cost of a solar loan, pulling more homeowners into the economic window where solar makes sense. Fed rate cuts are the single most powerful catalyst for Enphase revenue recovery. Monitoring Fed policy expectations and actual rate movements is the most important external variable for Enphase’s near-term outlook.

2. IQ Battery Attach Rate Growth The percentage of new solar installations that include a battery (the “attach rate”) has been rising and is structurally important. If attach rates reach 50%+ consistently (up from ~30% in recent years), IQ Battery revenue could double or triple without any market share gain — just from the structural shift in what customers buy. NEM 3.0 is a permanent structural driver of higher attach rates in California. Monitoring attach rate trends in Enphase’s quarterly shipment data is a key forward indicator.

3. SolarEdge’s Competitive Position SolarEdge’s severe financial difficulties — revenue collapsed from ~$3.5B at peak to under $1B, with massive inventory write-downs and executive departures — represent the biggest competitive gift Enphase has received in years. Installers who might have chosen SolarEdge on cost grounds are increasingly defaulting to Enphase as the safe, stable choice. How completely Enphase capitalizes on SolarEdge’s distress will be visible in U.S. market share data.

4. IRA Section 45X Credit Durability Enphase’s U.S. manufacturing expansion was explicitly motivated by the 45X production tax credits. These credits provide material per-unit margin benefit. Any rollback or modification of the IRA’s manufacturing credits under a future administration would reduce Enphase’s gross margin benefit and potentially make domestic manufacturing less competitive. This is a policy risk unique to the current legislative environment.

5. European Market Expansion Europe is 28% of Enphase’s revenue and declined less than the U.S. in 2024. European energy prices remain elevated, policy support for distributed solar is strong across Germany, France, Netherlands, and Belgium, and Chinese competitors face some (though limited) regulatory friction. Growing European revenue share would reduce Enphase’s dependence on the rate-sensitive U.S. residential solar cycle.

6. IQ9 Platform and Next-Generation Panel Support Solar panels are on a rapid efficiency improvement trajectory — panel wattages that were 400–450W in 2022 are reaching 550–600W+ today, with 700W+ panels emerging. Enphase’s IQ9 platform, designed to support these higher-wattage panels, is the product roadmap item most critical to defending microinverter attachment as panel technology advances. Timely IQ9 launch and strong installer adoption will determine whether Enphase maintains its per-panel attach rate as the panel market evolves.

7. Virtual Power Plants and Grid Services Enphase has millions of devices (microinverters and batteries) in homes globally — an aggregated asset that can be coordinated to provide grid services (demand response, frequency regulation, peak load reduction). Early-stage virtual power plant (VPP) programs with utilities could eventually become a meaningful recurring revenue stream, converting Enphase’s installed hardware base into a software-monetized grid asset. This is nascent but strategically significant.

8. Competition from Chinese Manufacturers in International Markets Huawei, Sungrow, and Growatt compete aggressively on price in European, Australian, and emerging markets. While Enphase commands a premium on product quality and system reliability, price-sensitive markets (particularly commercial rooftop) may gravitate toward lower-cost alternatives. Monitoring Enphase’s international gross margin and market share data will indicate whether premium pricing is being maintained.

Enphase Energy (ENPH) Financial Summary

Enphase Energy (ENPH) is a Clean Energy / Solar company that generated $1.63 billion in total revenue in 2024 — down -28.8% from peak in one of the sharpest single-year contractions the residential solar industry has experienced. The decline was driven by rate-sensitive demand collapse, California NEM 3.0 policy disruption, and distributor inventory destocking.

Despite the downturn, Enphase maintained gross margin above 39%, stayed free cash flow positive (~$300M), and grew IQ Battery revenue +60% — demonstrating the resilience of its technology-differentiated model. Operating margin collapsed to 1.8% due to operating leverage (fixed costs not declining with revenue) — which is also the reason margins should expand sharply on recovery.

The forward investment thesis centers on: interest rate cuts unlocking pent-up residential solar demand, IQ Battery attach rates continuing to rise (structurally supported by NEM 3.0), SolarEdge’s competitive retreat creating U.S. market share opportunity, and IRA Section 45X credits supporting gross margin as volumes recover.

Frequently Asked Questions

How does Enphase Energy make money? Enphase sells solar microinverters (72% of revenue), IQ Battery home storage systems (25%), and EV chargers and accessories (3%) to solar installers and distributors. In 2024, total revenue was $1.63 billion, down -28.8% from $2.29B in 2023.

What is a microinverter? A microinverter converts the DC electricity from a single solar panel into household AC electricity. Enphase puts one on each panel, unlike string inverters (one per whole system). This enables each panel to perform independently regardless of shading, adds safety (no high-voltage DC wiring), and enables panel-level monitoring.

Why did Enphase revenue fall in 2024? Three factors: (1) high interest rates made solar financing expensive, reducing consumer demand; (2) California’s NEM 3.0 policy dramatically reduced solar export compensation, disrupting California’s market; and (3) distributors drew down excess inventory rather than ordering from Enphase, amplifying the revenue decline beyond actual end-demand weakness.

Is Enphase Energy profitable? Yes, minimally. Net income was $0.05B (3.1% margin) in 2024, down from $0.44B in 2023. Free cash flow remained positive at ~$300M. The operating margin collapse to 1.8% was a volume/leverage problem, not a fundamental business deterioration.

Who are Enphase’s main competitors? SolarEdge (power optimizers + string inverters; financially distressed as of 2024) is the primary tech rival. Tesla Powerwall competes in home batteries. Chinese manufacturers (Huawei, Sungrow) compete in international markets.

What is the IQ8 microinverter? Enphase’s current microinverter generation, notable for Sunlight Backup — the ability to power critical home loads from solar panels during a grid outage, without a battery. It’s a grid-forming inverter, the only residential microinverter with this capability.

What is the IRA Section 45X credit? A U.S. production tax credit of $0.065/watt for domestically manufactured inverters under the Inflation Reduction Act. Enphase built a facility in South Carolina to qualify. The credit reduces COGS and improves gross margin for U.S.-manufactured units.

What is the IQ Battery? Enphase’s home energy storage product — a lithium iron phosphate (LFP) battery that stores excess solar for nighttime use, grid outage backup, or peak-rate avoidance. Revenue grew +60% in 2024. Available in 5 kWh, 10 kWh, and stacked configurations.

Does Enphase pay a dividend? No. Enphase reinvests cash into R&D and manufacturing, and has used its cash position to repurchase shares at depressed valuations during the 2024 downturn.

What is Enphase’s gross margin? 39.9% in 2024, down from 45.4% in 2023. The decline is primarily a volume deleveraging issue. Recovery in volumes, combined with IRA 45X credits from U.S. manufacturing, should restore margins toward the 40–45% range on a revenue recovery.
