Frequently-Asked Questions

Q1: What is the switch over time to backup power?

In 20ms.

Q2: What to consider when connecting to solar panels?

1). Avoid thin-film panels;
2). Total open-circuit voltage: 240V - 500V;
3). Use panels with the same specs in an array.

Q3: Can I connect the EP800 directly to my home's existing service panel / main panel to run house loads?

Not recommended. We suggest using a sub panel for essential loads, and ensuring the total load remains under 7.6kW.

Q4: Why do I need a BLUETTI sub panel?

For troubleshooting and maintenance. The sub panel has a manual switch that allows you to switch for switching between generator and grid power during daily use and malfunctions.

Q5: Will the EP800 kick in automatically during an outage?

Yes, the EP800 provides uninterrupted backup power to essential loads during a power outage. When the grid is restored, connected loads resume automatically without manual intervention.

Q6: What’s the difference between EP800 and EP900?

The EP800's off-grid installation is relatively simple and fast, perfect for customers installing a new energy storage system for the first time. While EP900 offers better compatibility, making it ideal for customers who want to integrate battery storage with their existing solar systems.

Q7: Does BLUETTI offer product liability insurance for EP800?

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

Q8: How many battery packs can I connect to the EP800, and what's the maximum capacity?

Each EP800 inverter accepts 2-4 B500 battery packs (4.96kWh for each) for a total capacity of 9,920Wh-19,840Wh. With two EP800 inverters in parallel connection, the maximum capacity can reach 19,840Wh-39,680Wh with 4-8 B500 batteries.

Q9: Is the EP800 compatible with other expansion batteries like the B300, B300S, or B230?

No, the EP800 only works with B500 battery packs.

Q10: Can I connect a third-party inverter with B500 batteries?

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

Q11: Is it necessary to ground the EP800 unit?

Yes, grounding the EP800 unit is necessary for safety reasons and proper functionality.

Based on 3 reviews
Great add-on for my Bluetti AC200Max

Now, I can recharge faster with this charging enhancer. It allows me to use both solar and AC at the same time resulting in 1,400W instead of just the 900W from solar alone. Also, I can use my regular AC Charger and the Charging Enhancer at the same time on both the main unit as well as the B230 battery. AND, I can use solar on the B230 battery too. Gives me more options to recharge my setup.

We're thrilled to learn this worked out so well for you. Thank you for your review!

Good solar panel

Easy to set up and sturdy carrying case. My only issue: unable to capture more than 300 watts, even in the brightest sunlight.
