Fortress Power introduces 9.6 kWh stackable home battery

US-based Fortress Power has unveiled its new residential lithium ferro-phosphate energy storage system.

The battery is built with independent, modular units offering 9.6 kWh and which can be stacked for up to three units, bringing 28.8 kWh. Multiple eForce batteries can be connected for up to 153 kWh of storage capacity.

Fortress Power said the batteries can be installed in parallel with a cableless system. The unit can be connected to the cloud and to an app for monitoring and firmware updates.

“Each stack connects via the eWay, a specialized wireway with built-in busbars, conduit ports, an emergency switch, and real-time status LEDs,” said the company. “The Envy True, 12 kW inverter bolts directly onto the eWay.”

The eForce battery can be used with Fortress Power’s Envy line of inverters, sized at 8 kW, 10 kW, and 12 kW. Both the battery and inverter are rated for indoor and outdoor installation and for wall- or ground-mounted configuration. The product has an active heating system for resilient operation in cold weather.

The batteries have 48 V nominal voltage and 3,000 A, five-millisecond short-circuit protection. The eForce battery has a 10-year workmanship and manufacturer warranty for 3,000 cycles at 100% depth-of-discharge, or 8,000 cycles at a 70% depth-of-discharge, whichever occurs first.

The product is available in North America and Latin America and is compatible with grid-connected and off-grid applications.

Fortress Power said the product is National Electrical CodeNEC and National Environmental Policy Act code-compliant, has an IP65 all-weather design, and is rated for UL 1973, UL 9540, and UL 9640A safety standards.
