Generac has built backup power since 1959 and is the number one manufacturer of home backup generators in the US. PowerStore carries the PWRcell ecosystem: battery modules and cabinets, inverters, PV Link optimizers, and energy management hardware.


PWRcell links PV Link optimizers, the battery cabinet, and a bidirectional inverter over Generac's REbus 380 VDC nanogrid, so solar, storage, and backup work as one system.
PowerStore lists PWRcell battery modules, the battery cabinet, 7.6kW and 11.4kW inverters, PV Link optimizers, SnapRS disconnects, and Smart Management Modules. Use the product list below to build out a complete system by SKU.
Our team helps installers size PWRcell storage to backup loads, plan module counts and cabinet configurations, and pair the right transfer switch hardware for whole-home coverage.


Yes. Add an external transfer switch for whole home backup, up to 9kW with one six module cabinet or 11kW with two cabinets. PWRmanager automatically sheds lower priority circuits to extend battery runtime.
Each PWRcell Battery Cabinet holds three to six modules, delivering 9 to 18kWh of usable storage. Connect two cabinets to a single inverter for up to 36kWh, and existing cabinets accept additional modules anytime.
Generac backs the PWRcell inverter, battery cabinet, and PWRmanager for 10 years. Battery modules carry a 10 year or 7.56MWh warranty with 70 percent capacity retention. PV Link and SnapRS get 25 years.
