Bluetti EP900 Energy Storage System Brings Whole-Home Power Outage Backup To The U.S. – SlashGear

Up to four B500 batteries can be connected to the same EP900 unit, however, and a system can support two EP900 units working in tandem. That expands total capacity to 39 kWh. With the average U.S. home consuming 1.2 kW per hour, Bluetti’s system could run a household for more than a day. Focusing use on the essential appliances like lights and heating, meanwhile, would stretch that out even longer.

Clad in an aluminum shell, both the EP900 and the B500 expansion batteries are rated IP65 waterproof and dustproof. That means they can be installed both indoors or outdoors, while a freestanding design adds flexibility of positioning, unlike wall-mounted rival systems. Owners can remotely monitor state of charge, discharge, battery health, and other factors from the Bluetti smartphone app, either directly via Bluetooth, or from anywhere in the world thanks to the EP900’s WiFi connection.

Like other recent Bluetti power solutions, the B500 relies on lithium iron phosphate (LiFePO4) batteries rather than lithium-ion. LiFePO4 batteries, the company says, have an effective lifespan that’s 4-6 times longer than Li-Ion, an obvious consideration for a home power backup system. Meanwhile, the EP900 has a 10 year warranty, the longest of any Bluetti product.
