BLUETTI EP900 + B500 Home Battery Backup - EP900 + B500 x 2

BLUETTI EP900 + B500 Home Battery Backup

Flexible Energy Solution, Grid Optional

Flexible Energy Solution, Grid Optional
With an impressive 10-20kWh energy storage capacity and up to 9,000W of continuous output power, the EP900 can accommodate all your daily needs. It provides safe, reliable backup power during utility power outages. Power all your 120V and 240V appliances and sell any excess energy to the Utility. A smart investment that can pay for itself and even generate income in the long run.

How Does EP900 Benefit Our Life?

Harness Solar Energy Anytime Energy Bill Savings

Solar panels generate electricity during daylight hours-often generating in excess of actual daytime demand. Adding a battery energy storage system captures this excess solar energy and makes it available for later use. Harness solar energy anytime with the EP900, even when the sun is not shining.
If you've installed a PV inverter, your batteries will charge from solar energy while the grid is operational, and the BLUETTI app will display the amount of energy generated from solar.
Please Note: however, that your existing PV inverter (with the exception of the IQ7 model) cannot charge the EP900 ESS during a grid power outage.

Power Outage Protection

Living on the outskirt of town brings closer contact with nature. However, the power fluctuation, extreme weather events, and natural disasters in the coming season could drag your home into darkness at any time. Spruce up your house with BLUETTI EP900, then you don't have to exclusively rely on the grid to keep the electrics running since plenty of solar energy has your needs covered.

Lower Utility Bills

Peak Load Shifting allows you to charge EP900 with low-price grid power or free solar energy , and discharge during peak hours (normally from 4pm to 10pm) to considerably drive down the costs of electricity.

Smart Investment

Rather than leaving the surplus solar power wasted, now by integrating EP900 into the main grid, you can sell the excess power back to the utility provider to earn money.

120V/240V Dual Voltage

Take Care Of All Your Devices

To power 240V appliances and power tools at your home or worksite, an energy storage system with high-voltage output capability is required. While most products in the market can provide either 120V or 240V, the EP900 system can simultaneously supply both from a single base unit.

Ultra-Wide Compatibility Max. 9kW input

You can also integrate EP900&B500 into the main grid as a backup power without solar system.

For Your Peace of Mind

Frequently Asked Questions

What should I do if the SoC readings are inaccurate?

If you notice significant momentary fluctuations in the SoC, try performing two complete charge and discharge cycles on your inverter. This will help recalibrate the system and restore accurate SoC readings.
