Home Battery System GuideGenerac is a large home power brand best known for generators. Its PWRcell brings modular battery storage to the home. Owners scale capacity by adding battery modules.
Capacity and Power Output
Generac builds PWRcell from individual 3.0 kWh battery modules. A single cabinet scales from 9 to 36 kWh depending on module count. Generac states the modular PWRcell system provides up to 36 kWh of storage capacity.
Continuous power scales with module count. Generac lists 3.4 kW continuous with 3 modules and 6.7 kW continuous with 6 modules. The same table shows higher short term figures, up to 9 kW with 6 modules.
This modular design lets owners start small and grow. Capacity and power both rise as modules are added.
Warranty
Generac backs the PWRcell battery with a 10 Year Limited Warranty. The warranty term is listed in the official PWRcell consumer brochure.
Other system components carry their own terms. Generac lists a 25 Year Limited Warranty for the PV Link and SnapRS devices.
