eForce 9.6kWh
The cutting-edge eForce batteries have built-in temperature sensor-controlled heat in each battery module, designed for all weather. Each of these modular LFP Lithium batteries has an energy capacity of 9.6kWh. The eForce batteries are stackable, with up to three units per stack. Up to 16 eForce batteries can be used in a single system, providing a total energy storage capacity of up to 153kWh. When the batteries are stacked on top of each other, no battery cables are needed to interconnect and parallel the units within the stack, as the battery terminals simply click into place. This makes installation quicker, easier, and more cost-effective.
Each eForce stack is completed with an eWay, the designated wireway for the eForce batteries. The eWay contains busbars that eliminate the need for troughs or similar components to connect the eForce battery stacks as well as the Envy True 12kW inverter(s). The eWay also features conduit entrance ports of different diameters, an emergency switch, and an LED display that shows the battery stack status in real-time. The Envy True 12kW inverter can be directly bolted on top of the eWay, creating a powerful, sleek, and complete energy storage tower with all of the required components in it. The eForce, alongside with the eWay, can be used in any application for which the Envy inverters are suitable, thus creating one energy storage solution from Fortress Power to meet and exceed your energy needs.
8000 cycles guarantee, 10-year warranty and highest quality standard, make it perfect for both your homes, businesses, condos, off grid cabins and so on.
