PWRcell 2 keeps you powered and in control with intelligent home energy management.
Getting solar panels for your home is great way to save on your electric bill and contribute to a cleaner world - but what if you could multiply those benefits and gain reliable backup power, day or night?
Meet PWRcell 2, a smart battery storage system that puts you in control of the clean energy you generate—delivering reliable backup power, lower energy costs, and peace of mind when you need it most.
A reliable home starts with reliable power. With Outage Guard, your system automatically prepares for severe weather by maximizing battery charge ahead of a storm. When the grid goes down, PWRcell 2 takes over, using stored energy to keep your home powered.
Instead of wondering where your energy goes, decide where it stays. PWRmanager gives you circuit-level control of your home, right from your phone. While on battery power, it can automatically shut off non‑essential loads to extend battery life, while still letting you turn individual circuits on or off at any time. Keep your whole home powered for a short outage, or switch to just the essentials for the long haul - the power is yours.
Adding battery storage to your solar unlocks even more ways to save. With PWRcell 2, you can store excess solar energy during the day and use it at night—reducing your reliance on the grid and helping lower your energy bills.
But PWRcell 2 doesn’t just store power; it masters it. Bill Savings mode automatically optimizes around Time-of-Use (TOU) rates and demand charges. After identifying your local utility rates, our system charges when electricity is cheaper and uses stored energy when rates are higher - so you save more without even thinking about it.
Your ecobee by Generac smart thermostat provides a convenient in-home display for solar production, battery status and outage alerts. During outages, it can also automatically adjust temperature set points to preserve stored energy and help extend backup power.
Choosing Generac solar battery storage means joining the movement toward a smarter, cleaner future. In 2024, PWRcell systems across the country produced 259 GWh of energy, helping prevent an estimated ~165,000 metric tons of CO₂ from entering the atmosphere.
With our ecobee by Generac smart thermostat and app, you can see exactly how much of your home is powered by the sun. It’s a clear view of your impact, and the ultimate shortcut to a smaller footprint and a more sustainable, solar-powered lifestyle.

PWRcell 2 is a battery storage system that harnesses power from the sun or the electric grid to help you reduce energy costs, minimize your reliance on the electric grid, and be prepared for unexpected power outages. Every PWRcell 2 system consists of one Generac Smart Disconnect Switch (SDS), one inverter, at least one battery cabinet, at least three lithium-ion battery modules, one PWRmanager load management device, and an ecobee Smart Thermostat Enhanced.
PWRcell 2 stores energy from either solar panels or the grid in lithium-ion battery modules. The inverter converts the stored energy from direct current (DC) energy into alternating current (AC) energy which can be used to power your home during peak demand times or utility power outages.
Generac does not manufacture or distribute solar panels, but our storage solutions are compatible with most panels. Authorized Generac installers can help you select and purchase the right panels for your home and install the entire system.
How long your battery lasts depends on several factors including:
Battery storage system sizing is a critical part of your consultation, so make sure to discuss desired usage plans with your local authorized Generac installer. PWRcell 2 is available in configurations from 9 to 36 kWh of battery capacity—your installer can help size the system based on your usage and backup goals.
A home battery like PWRcell 2 enables you to store energy from solar or the grid and use it to power your home at night and during peak demand times when utility rates are most expensive. Compared to solar power alone, when you are limited to offsetting utility costs when the sun is shining.
Expand your energy independence how and when you choose with the Generac Home Energy System. Add a home standby to get the ultimate peace of mind and energy independence with virtually endless* backup capabilities. When battery levels get low, the generator will automatically kick on to simultaneously power the home and recharge the battery.
*Subject to fuel availability.
