Bluetti EP900 Energy Storage System

Flexible Energy Solution, Grid Optional

Featured with an impressive 10kWh-20kWh capacity and up to 9kW continuous output, Bluetti EP900 delivers an ideal investment solution to secure your home from power failures, store the surplus solar energy for any time, and even sell it back to the grid for a long-term positive ROI.

Superpower For Heavy-duty Work

The Bluetti EP900 has a 9kW inverter that provides either 120V or 240V output options, making it suitable for high-wattage appliances - like power tools in small business and residential scenarios. Combine two EP900 units in parallel to reach as much as 18kW output, which is enough to power the whole house without any fuss.

Power Your Home for Weeks

Teaming up with B500 expansion batteries, you can expand the capacity from 9.9kWh to 39kWh to meet your power demands of most households.

Charge Safer, Last Longer

Bluetti EP900 is built with the most reliable LiFePO4 battery cells for the sake of an extended lifespan and safe operation. A comprehensive 10-year warranty is also included to take any hassle out of your journey towards energy self-sufficiency.

Real-time Control At A Distance

Whether you're at home or on the go, you can seamlessly control the Bluetti EP900 from your phone. Set up working mode, manage power consumption, view charging status, and even perform OTA updates, all in a matter of clicks.


The Bluetti EP900 is constructed with a rugged aluminum shell which has an IP65 rating to resist daily wear and tear. While adding a protective case helps to maintain optimal performance even in harsh conditions.

Easy Installation

Unlike most wall-mounted home batteries in the market, EP900 applies no pressure to the wall. Simply stack up your battery system, place it on the ground, and have it fixed against the wall outdoors or indoors. BLUETTI also provides a certified installation service to free your unwanted hassles.
