Backup and savings with the Fortress Power eBoost DC Energy Storage System
From 16.08 kWh to 48.23 kWh of storage, the Fortress Power eBoost DC Energy Storage System stores daytime solar for the evening and night, and with a backup-capable installation keeps a home running through a power cut. It delivers 12.8 kW of AC power (up to 38.4 kW in larger configurations), enough to run heat pumps, ovens and air conditioning alongside the rest of the house.
One full charge covers about 54% 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.
