What products work with B500?

The B500 is designed to work exclusively with BLUETTI's EP800 and EP900 Energy Storage Systems.

Can I connect the B500 directly to my home's existing main panel to run house loads?

No, an EP800 or EP900 is needed for the B500 to work. We suggest using a sub panel for essential loads.

Why do I need a BLUETTI sub panel?

For troubleshooting and maintenance. The sub panel has a manual switch that allows you to switch to the generator side for daily use, and the grid side when malfunctions.

In case of an outage, will the system kick in automatically?

Yes. When the power grid fails, the energy storage system provides an uninterrupted power to the BACKUP loads. When the grid is restored, the GRID loads resume without manual intervention.

Does BLUETTI offer product liability insurance for its products?

Yes, we have purchased third-party product liability insurance worldwide.

How can I customize or determine the battery capacity I need based on my essential loads?

How many battery packs can I connect, and what's the maximum capacity?

Up to 4 battery packs (4.96kWh for each), allowing a max. storage capacity of 19.84kWh.

Is the B500 compatible with other Bluetti expansion batteries, such as the B300, B300S, or B230?

No, the B500 only works with EP800 and EP900, and it does not works with other types of expansion batteries.

Can I connect a third-party inverter with B500 batteries?

No. The B500 expansion battery is exclusively designed for the EP800 and EP900.

Is it necessary to ground the B500 unit?

Yes, grounding the B500 unit is necessary for safety reasons and proper functionality.

Can I install the energy storage system by myself?

No. For safety reasons, the system must be installed by a licensed electrician. PEGASAT can provide a qualified electrician for professional installation, or customer can choose to use their own electrician. Please contact PEGASAT at: [email protected] for questions regarding the installation process or a cost.
