Enphase debuts a new US off-grid solar and battery system

Enphase Energy just launched a new off-grid system that lets homeowners power their homes without a utility connection – even for extended periods. The California-based Enphase says the off-grid setup delivers a seamless way to live independently from the grid while still using solar, batteries, and a standby AC generator.

A full off-grid setup

The new system combines Enphase’s IQ Battery 5P with embedded grid-forming microinverters, IQ8 Series Microinverters with Sunlight JumpStart, and a third-party standby AC generator. The components work together to supply power to a home and automatically manage energy sources to maximize efficiency and reliability.

If the batteries are drained and the generator runs out of fuel, the Sunlight JumpStart feature can automatically recharge the batteries the next morning once the sun comes up.

The IQ Battery 5P delivers 3.84 kVA of power per 5 kWh of capacity, and systems can be scaled up to 40 kWh and 15.4 kVA. That’s enough power to start big household appliances like HVAC systems or water pumps. The IQ System Controller 3G provides the backbone, managing solar, batteries, and generator inputs to deliver up to 46 kVA of off-grid power.

Smarter control and connectivity

Each system connects to the cloud through Enphase’s IQ Combiner 5C HDK, which bundles solar interconnection, communications, and metering into one box. For homes without reliable broadband, the built-in 4G LTE Cat 4 modem keeps the system online for monitoring, firmware updates, and remote support.

Homeowners can manage everything from the Enphase App – from solar generation and battery status to generator integration and load control.

Why it matters

As grid outages become more common and homeowners look for ways to gain energy independence, off-grid systems like this are becoming more appealing.

“With the launch of our off-grid solution, we are giving homeowners a reliable path to complete energy independence,” said Nitish Mathur, Enphase’s SVP of customer experience. Enphase says over 100 homes are already operating entirely off-grid using its technology. The company plans to expand availability beyond the US in 2026.
