PWRcell 2 is designed to maximize energy savings and bring you peace of mind with clean, reliable backup power. Pair PWRcell 2 with a PWRmicro Solar Microinverter for even more power, greater savings and reliability.
Produce, store, and manage your own energy, reducing reliance on an unstable grid.
Store solar power your panels have already harnessed so it’s ready to use during an outage. Add a Generac Home Standby Generator for the ultimate peace of mind.
Switch to stored solar energy to offset peak costs. Plus, use what you’ve harnessed during the day to power your home at night.
Explore how this complete system helps you store clean solar power to save on energy bills and self-supply power during an outage.
PWRcell 2 features one of the highest residential storage capacities available, providing not only additional savings opportunities compared to solar alone, but also up to 33% more backup capability than the current solar storage industry leader.
Adding a Generac home standby generator up to 28 kW provides 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.

Get answers to frequently asked questions about the PWRcell 2 Solar Battery Storage System.
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, one battery cabinet, at least three lithium-ion battery modules, 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 how large (kWh) your battery is, how much power your home uses over a certain time, and how much power (kW) your inverter is rated to push through to your house at a given time.
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 offers you the ability to offset your usage of the electric grid. During peak demand times, when utility prices are at their highest, the stored energy can be deployed to power your home, helping you minimize usage of the highest cost energy from the grid.
