Bluetti EP900: The 9kW/9.9kWh Whole-House Energy Storage System – Bluetti EP900 Vs. EP600 Vs. EP500 Pro

Bluett showed off the US version of its EP600+B500 home energy storage system at CES 2023 in Las Vegas. Branded as the Bluetti EP900+B500, the US variant is to come with a more powerful 9000W inverter bundled with the same B500 4960Wh external battery packs.

It is a 9.9kWh/19.8kWh modular home battery with an inverter of 9000 watts. It can offer you both 120V and 240V options without the need to tie together two units. You can increase its capacity to 19.8kWh with the use of the B500 extra battery packs.

By the way, with two units of the EP900s paired, you can further crank up the total storage capacity to a massive 39.6kWh, which can certainly make it a strong alternative to the Zendure SuperBase V and Tesla Powerwall.

As you may know, the EP600+B500 is Bluetti’s whole-house home storage system for the European regions, and it was launched at IFA 2022 in Germany.

The EP600 is a 9.9kWh/79.3kWh home backup system with a 6000W pure sine wave inverter and a solar input of 6000 watts. Most likely, the new EP900+B300 will also be featuring super-fast solar and AC charging inputs to make it a reliable home backup power system.

Update – April 2023: Bluetti officially unveiled the EP900 and B500 in April 2023. The main specs and features of the product have been teased on its website. The price and release date details of the massive home backup system are yet to be announced, though.
