Collection: Residential ESS LiFePO4 Batteries

Add battery storage to your home solar system with an energy storage system (ESS) built to pair with a grid-tie or hybrid inverter. Choose from single 5kWh units — like the GSL Energy Powerlite and Growatt ALP LV-US (48–51.2V) — up to expandable systems reaching 20kWh–61.44kWh, so you can start small and scale up without replacing the whole system.

Most units support parallel connection for expansion, are cobalt-free LiFePO4 chemistry, and include built-in BMS protection plus CAN/RS485 communication for inverter monitoring. Higher-capacity options are rated for 90% depth of discharge and -10°C to 50°C operation, holding up well through a Canadian winter — with IP65-rated outdoor models also available.
