Neglected PV Maintenance Fuels Fire Risk

Enphase Energy, Inc. (NASDAQ: ENPH), a global energy technology company and the world's leading supplier of microinverter-based solar and battery systems, announced support for complete off-grid system configurations that are capable of operating without a utility connection when needed. The system requires the IQ Battery 5P with embedded grid-forming microinverters, IQ8 Series Microinverters with Sunlight JumpStart capability, and a third-party standby AC generator, which all work together to power the home.

The comprehensive off-grid solution from Enphase is designed to meet the unique power needs of homeowners. For off-grid use cases, the components of the Enphase Energy System collaborate to power loads and charge batteries efficiently, with intelligent software optimizing generator usage when required and preventing generator damage from back-feeding power. The enhanced software also includes a new “Off-Grid” system profile that can be selected during commissioning, enabling smooth operation without the utility grid while operating alongside a generator.

With more homeowners seeking energy independence due to rising outages and grid instability, Enphase’s off-grid solution is designed to complement the utility grid by meeting today’s growing demand for reliable and resilient power. Off-grid capabilities have been integrated into several components of the Enphase Energy System, including:

• IQ8 Series Microinverters. With grid-forming capabilities, the IQ8 Series Microinverters offer Sunlight JumpStart capability. If the microgrid collapses because the batteries are fully discharged and the generator is out of fuel, Sunlight JumpStart is designed to automatically recharge the batteries and restore power the next morning.
• IQ Battery 5P. Enphase’s third-generation battery offers 3.84 kVA of power per 5 kWh of energy capacity. With Enphase Power Control, you can scale your system to 40 kWh of capacity and 15.4 kVA of power. With this power, homeowners can start large household loads, including HVAC systems and water pumps.
• IQ System Controller 3G. The system controller integrates an autotransformer to provide 120/240 V split-phase AC and a Generator Interconnect Device (GID) to parallel an AC standby generator with batteries and solar. Users can connect up to 15.4 kW of solar and 40 kWh of IQ Batteries, as well as draw up to 15.4 kVA from an AC standby generator, thereby providing up to 46 kVA of power while off-grid. In addition, the support for load control enables users to automatically control loads based on whether the sun is shining, the generator is connected, and adequate energy is available in the batteries.

Each off-grid system can now connect to the cloud through the Enphase IQ Combiner 5C HDK, which consolidates solar interconnection, communications, and metering within a single enclosure. For sites without reliable broadband access, the integrated 4G LTE Cat 4 Modem delivers dual-SIM connectivity with automatic failover, ensuring the system stays online for real-time monitoring, firmware updates, and remote diagnostics. Enphase also offers the modem as a standalone accessory for customers using legacy IQ Combiner 5 units currently available in the channel.

“Thanks to Enphase, we can now offer our customers a complete solar and battery backup system that provides true off-grid living,” said Caleb, CEO of Haven Acres. “The microinverter-based system uses low-voltage alternating current wiring that allows us to build simple, safer systems – even with large electricity loads – and support homeowners in powering as much of their lives as possible with sunshine.”

“We’re excited to finally provide complete energy independence to our customers, with everything controlled through the Enphase App,” said Bob Evans, president of Evans Energy Systems. “Thanks to the generator integration feature, along with solar and storage, our customers can have dependable power in locations that do not have the grid or for customers that do not want the grid.”

“With the launch of our off-grid solution, we are giving homeowners a reliable path to complete energy independence,” said Nitish Mathur, SVP of customer experience at Enphase Energy. “There are already more than 100 fully off-grid sites using Enphase products today and performing reliably under real-world conditions. By combining grid-forming batteries, Sunlight JumpStart technology, and integrated generator support, the Enphase Energy System can deliver dependable power 24x7, all managed through a single app.”

The off-grid system solution from Enphase is available to customers in the United States today and is expected to roll out to additional countries throughout 2026.

A review by the SUN DAY Campaign of data just released by the U.S. Energy Information Administration (EIA) reveals that solar and battery storage have dominated growth among competing energy sources while fossil fuels and nuclear power have stagnated.

Solar electrical generation set new records in August and the first two-thirds of 2025:

EIA’s latest monthly "Electric Power Monthly" report (with data through August 31, 2025), once again confirms that solar is the fastest growing among the major sources of U.S. electricity.

In August alone, electrical generation by utility-scale solar (i.e., >1-megawatt (MW)) ballooned by almost one-third (29.5%) compared to August 2024 while “estimated” small-scale (e.g., rooftop) solar PV increased by 10.8%. Combined, they grew by 24.7% and provided nearly one-tenth (9.5%) of the nation’s electrical output during the month, up from 7.6% a year ago. [1]

Moreover, utility-scale solar thermal and photovoltaic expanded by 35.7% while that from small-scale systems rose by 11.0% during the first eight months of 2025 compared to the same period in 2024. The combination of utility-scale and small-scale solar increased by almost a third (28.8%) and was over 8.9% (utility-scale: 6.7%; small-scale: 2.2%) of total U.S. electrical generation for January-August - up from 7.1% a year earlier.

As a consequence, solar-generated electricity year-to-date (YTD) easily surpassed - by over 58% - the output of the nation’s hydropower plants (5.6% of total generation). In August alone, solar-generated electricity more than doubled the output of the nation’s hydropower plants. In fact, in both August and YTD, solar produced more electricity than hydropower, biomass, and geothermal combined. [2]

Moreover, for the second consecutive month, utility-scale solar generated more electricity than the nation’s wind farms – by 4% in July and by 15% in August. Including small-scale systems, solar has out-produced wind four months in a row and by almost 50% during August. [3]

Wind has also made a strong showing YTD:

Wind turbines across the U.S. produced over a tenth (10.2%) of U.S. electricity in the first eight months of 2025 – an increase of 2.6% compared to the same period a year earlier and 80% more than that produced by the nation’s hydropower plants.

Wind + solar are almost one-fifth of total U.S. electrical generation – a larger share than that provided by either coal or nuclear power:  

During the first eight months of 2025, electrical generation by wind plus utility-scale and small-scale solar provided almost a fifth (19.1%) of the U.S. total, up from 17.2% during the first two-thirds of 2024.

Further, the combination of wind and solar provided 16.2% more electricity than did coal during the first eight months of this year, and 11.7% more than the nation’s nuclear power plants. In fact, as solar and wind expanded, nuclear-generated electricity dropped by 0.7%.

Electrical output YTD by the mix of all renewables was over 26% of total U.S. generation:

The mix of all renewables (i.e., wind and solar plus hydropower, biomass and geothermal) produced 9.0% more electricity in January-August than they did a year ago and provided (26.1%) of total U.S. electricity production compared to 24.5% twelve months earlier.

Renewables’ share of electrical generation is now second to only that of natural gas whose electrical output actually dropped by almost 4.1% during the first eight months of 2025.  

During the past year, solar and battery storage have dominated capacity additions, coupled with a strong showing by wind:

Between September 1, 2024 and August 31, 2025, utility-scale solar capacity grew by 31,706.5-MW while an additional 5,718.1-MW was provided by small-scale solar. EIA foresees continued strong solar growth, with even more utility-scale solar capacity - 34,325.8-MW - being added in the next twelve months.

Strong growth was also experienced by battery storage which grew by 63.9% during the past year and added 13,377.5-MW of new capacity. In the course of the past year, battery storage actually surpassed pumped hydro storage (PHS) - in October 2024 - and now accounts for 50% more storage capacity than PHS. EIA also notes that planned battery capacity additions during the next year total 20,179.8-MW.

Wind also made a strong showing during the past twelve months, adding 4,791.9-MW, while planned capacity additions over the next year total 9,650.1-MW.

On the other hand, natural gas capacity increased by only 3,337.7-MW and nuclear power added a mere 46.0-MW. Meanwhile, coal capacity plummeted by 4,185.1-MW and petroleum-based capacity fell by an additional 658.7-MW.

Thus, during the past year, renewable energy capacity, including battery storage and small-scale solar, ballooned by 55,419.6-MW while that of all fossil fuels and nuclear power combined actually declined by 1,486.3-MW. [4]

"The Trump Administration and its Republican supporters in Congress may slow renewable energy growth a bit," noted the SUN DAY Campaign's executive director Ken Bossong. "However, EIA’s data reinforce the conclusion that the transition to solar, wind, other renewables and storage continues, is accelerating, and has become inevitable."

[1] In its “Electric Power Monthly” report, EIA refers to small-scale or distributed solar as “Estimated Small Scale Solar Photovoltaic.” Unless otherwise indicated, all calculations presented in this release include electrical generation by small-scale solar which EIA estimates to have totaled 65,834-GWh in January-August 2025 and 9,319-GWh in August alone. Utility-scale solar totaled 207,722-GWh for the first eight months of 2025 and 31,501-GWH in just August.

[2] In January-August 2025, wind produced 311,246-GWh (10.2%) of total U.S. electrical generation while utility-scale and small-scale solar combined produced 273,555-GWh (8.9%), hydropower produced 172,751-GWh (5.6%), biomass produced 30,971-GWh (1.0%), and geothermal produced 10,499-GWh (>0.3%).

[3] In August alone, wind produced 27,297-GWh while utility-scale solar produced 31,501-GWh. The combination of utility-scale and small-scale solar totaled 40,820-GWh.
