Backup and savings with the Felicity Solar Megafelicity Ess

With 39.84 kWh of storage, the Felicity Solar Megafelicity Ess stores daytime solar for the evening and night, and with a backup-capable installation keeps a home running through a power cut. It delivers 5 kW of AC power (up to 10 kW in larger configurations), enough for most of a home's circuits at once.

One full charge covers about 135% 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.
