BLUETTI EP800 + B500 Home Battery Backup

Home Energy Backup Made Simple

EP800 Off-grid Energy Storage System

Life is So Much Easier with BLUETTI EP800

Home Backup

When facing the threat of extreme weather, the EP800 ESS prioritizes charging from both the grid and solar power to prepare for potential outages, making sure everything works out fine.

Self-consumption

Integrate the BLUETTI EP800 with new solar panels or existing rooftop microinverters to capture free solar energy on sunny days, efficiently powering your appliances

Time of Use

Customize the charging and recharging periods - recharge EP800 ESS from the grid when utility prices are low, and power your home with stored energy. Thus, you can avoid peak pricing and save on bills, even without solar.

Best Solution for Every Situation

As a versatile home energy storage system, the EP800 delivers backup power, cost savings, and net-zero emissions, whether you have a solar system or not.

 

Easy Installation, Easy Power

Quicker Installation

Satisfaction in Any Location

Tailored Energy Systems for Every Need

At BLUETTI, we know that there's no one-size-fits-all solution.
That's why we offer scalable capacity to adapt to your changing power demands.

*The above estimation is based on a 5kWh power consumption per day during outages. Use the calculator for a more accurate result based on your specific needs.

Frequently Asked Questions

What is the switch over time to backup power?

in 20ms.

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.

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.

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.

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.

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.

Does BLUETTI offer product liability insurance for EP800?

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

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.

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

No, the EP800 only works with B500 battery packs.

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

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

Is it necessary to ground the EP800 unit?

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

Can I install the EP800 unit by myself?

No. For safety reasons, the system must be installed by a licensed electrician. BLUETTI provides authorized installers for professional installation. Once you place your order, our service team will guide you through the whole process

Can I charge the EP800 via solar and grid power simultaneously?

Yes, the EP800 accepts both solar and grid power simultaneously with a maximum input of 9kW. The system always prioritizes solar charging.

Does EP800 support AC coupling?

Yes, the EP800 supports AC coupling with existing PV inverters. Contact BLUETTI Customer Service for more details.

Can I charge and discharge EP800 at the same time?

Yes, EP800 supports pass-through charging.

What information should I provide for EP800 troubleshooting?

Please provide your order number, product serial number (SN), alarm history, error code, and firmware version for efficient diagnosis and resolution

What's the process for ordering the EP800?

1) Place your order or schedule a free consultation. 2) Confirm the availability of trusted electricians for installation. If needed, our certified installer can assist with additional installation fees. 3) Receive in-depth training for your electrician to ensure proper installation. 4) Sit back and relax as we assist with the installation process. 5) Contact us for any post-installation support or assistance.
