Generac PWRcell in Hume
The Generac PWRcell is a modular battery system using 3 kWh battery modules (3–6 modules per cabinet) for 9–18 kWh per cabinet. It pairs with the PWRcell inverter and supports whole-home backup. Generac's generator heritage makes it a trusted name for backup power in the Central Valley.
Hume is a remote mountain community in eastern Fresno County, located near Kings Canyon National Park at approximately 5,200 feet elevation. Served by ZIP code 93628, Hume has a mix of full-time residences and vacation properties surrounded by Sierra Nevada forest. The high elevation delivers two solar advantages: cooler temperatures that keep panels closer to their rated output, and strong unobstructed sun exposure from spring through fall. PSPS outages are among the most frequent and prolonged in Fresno County — PG&E regularly shuts down the transmission lines serving this area for 48–72 hours or more during fire weather. For Hume homeowners, battery backup is not optional — it is essential infrastructure.
