Backup and savings with the Briggs & Stratton SPHI
From 6.65 kWh to 19.95 kWh of storage, the Briggs & Stratton SPHI stores daytime solar for the evening and night, and with a backup-capable installation keeps a home running through a power cut. It delivers 6.66 kW of AC power (up to 13.98 kW in larger configurations), enough for most of a home's circuits at once.
One full charge covers about 22% of an average US home's daily electricity use of 29.6 kWh.
Its LiFePO4 (lithium iron phosphate) cells are the long-life chemistry of home energy storage: rated for thousands of cycles and more thermally stable than other lithium-ion types.
