Bluetti EP800+B500 Home Battery Backup - Join the Energy Revolution

The BLUETTI EP800 isn't just an energy storage system; it's key to slashing energy costs during peak hours, securing uninterrupted power during outages, and embarking on a journey toward an off-grid living style. The easy installation of EP800 ensures great convenience to access power freedom without spending a lot of time and money.

Existing or Newly-installed? We’ve Got You Covered

The BLUETTI EP800 seamlessly integrates with your current solar system or can easily be paired with your new solar panels. By utilizing AC coupling, the EP800 can operate with your existing solar systems, eliminating the need for additional labor costs associated with rooftop solar panel wiring. For optimal efficiency, solar panels can also be directly connected to the EP800 via DC coupling.


Non-stop Power Supply

Don't let blackouts hold you back; rest assured that EP800 will always has your back since it kicks in within 20ms as soon as the power goes out, delivering seamless power to your essentials, such as refrigerators and CPAP equipment, ensuring your food stays fresh and your loved ones are well taken care of. Enjoy every moment with peace of mind, as worries about power blackouts become a thing of the past.


Discover Unbounded Energy Freedom

Embrace the freedom of living off the grid or indulging in nature-filled weekends at a remote cottage. With EP800, you'll have the power you need to enjoy the best of both worlds – the serenity of nature and the comfort of modern conveniences.

The Home Power at Your Fingertips

Everything about your EP800 is under control thanks to the intuitive BLUETTI App. Monitor real-time power consumption, seamlessly toggle between working modes, and conduct OTA updates, all from the palm of your hand, no matter where you are.

Customize Your Power Plant

By stacking 2 to 4 B500 expansion batteries (4960Wh each) on the bottom, you can tailor a capacity of 9.9kWh to 19.8kWh according to your needs. Also, the EP800 inverter delivers an awe-inspiring output of up to 7600W and 120V / 240V voltage options to energize your appliances effortlessly.

Bluetti EP800+B500 Home Battery Backup Q&A 

Q1: What’s the difference between EP800 and EP900?
A: EP800 is an off-grid energy storage system with a max output of 7600W, while EP900 is an on-grid/off-grid energy storage system with a max output of 9000W. Both of these system provide robust 120V and 240V split-phase backup power but EP800 solely focus on off-grid usage thus provide a more convenient and cost-efficient solution for off-grid installation.

Q2: Can I get the EP800 charged with home grid?
A: Yes, the EP800 can only be installed off-grid. However, it doesn’t mean you have to rely solely on solar. You can charge it from the grid, solar panels, or combine them simultaneously.

Q3: What does the 10-year warranty cover?
A: BLUETTI guarantees that with proper use as outlined in the user manual, each battery pack will achieve a minimum aggregate energy throughput of 15.48MWh during the warranty period.

Q4: Does the 10-year warranty policy apply to the fans and WiFi modules?
A: No. The warranty for the fans and WiFi modules is 24 months.

Q5: What is the noise level of the EP800?
A: Less than 50dB.

Q6: Can the EP800 prioritize solar power usage?
A: Yes, the EP760 has an intelligent energy management system that allows you to customize charging and discharging times, as well as the SoC limits via the BLUETTI App, to maximize the use of solar energy and minimize your electricity bills.

Q7: Can the EP800 be used with battery packs other than the B500, such as the B300, B300S, or B230?
A: No, the EP800 only works with B500 battery packs.

Q8: What is the UPS switching time?
A: In 20ms.

Q9: What is the weight capacity of each B500?
A: Over 441 lbs/200kg, meaning that an EP760 + 4*B500 combo can be stacked vertically, saving you plenty of space.

Q10: Can I install the EP800 unit by myself?
A: No, the system must be installed by a licensed electrician. We have a network of authorized installers available to offer professional local installation services for your convenience.

Q11: Are the EP800 and B500 water-resistant?
A: Yes, they are rated NEMA 4X that provides protection against water and dust.

Q12: Is the EP800 risky or prone to catching fire?
A: The EP800 is designed with a strong focus on safety and reliability. However, it's crucial to follow specific precautions to guarantee its long-term performance and safety. Please keep the device away from heat sources like heaters or open flames, avoid exposure to direct sunlight, and prevent severe impacts or contact with chemicals. Please note that any accidents resulting from these situations are not covered by the warranty.

Q13: Does BLUETTI offer product liability insurance for its products?
A: Yes, we have purchased third-party product liability insurance worldwide.

Q14: Does EP800 support DC coupling or AC coupling?
A: Yes. However, it's recommended to prioritize DC coupling since it’s more efficient and can be used during outages. The EP800 has two MPPT controllers that can handle up to 9,000W (6,000W + 3,000W) solar input via DC coupling and supports a voltage range of 150V-500V and a maximum working current of 12.5A/25A.

Q15: Can I use installed solar panels and inverter together with the EP800?
Yes. EP800 works with existing solar panels via DC coupling and existing solar systems(with inverter) via AC coupling. If your current inverter is aging and can't be repaired, EP800 can replace your malfunctioning inverter via DC coupling.

Q16: Is it necessary to ground the EP800 unit?
A: Yes, grounding the EP800 unit is necessary for safety reasons and proper functionality.

Q17: Can I charge EP800 with a gas generator?
A: Yes, you can.
