  • How Does EP900 Benefit Our Life?
    Solar panels generate electricity during daylight hours-often generating in excess of actual daytime demand. Adding a battery energy storage system captures this excess solar energy and makes it available for later use. Harness solar energy anytime with the EP900, even when the sun is not shining.
Astonishing 7,600W to 18,000W Output
Superpower For Heavy-duty Work
One single EP900 system provides up to 9,000W* of power, which can be doubled to 18,000W by connecting two units, enough to power the most home appliances without any fuss, such as washer, dryer, heater, refrigerator, and more. * The output power for a EP900+2*B500 combo is 7,600W while running off the grid.
120V/240V Dual Voltage

Take Care Of All Your Devices

To power 240V appliances and power tools at your home or worksite, an energy storage system with high-voltage output capability is required. While most products in the market can provide either 120V or 240V, the EP900 system can simultaneously supply both from a single base unit.

Power Your Home for Weeks
Thanks to its modular design, it is easy to stack up as your energy needs grow over time. With B500 (4,960Wh each) expansion batteries, you can expand the capacity from 9.9kWh to 39.6kWh to meet your power demands even for a few weeks.
