Keep Essential Power Running During Outages

The EASUN SGR-6.5KW-U helps power your most important 120V home loads—from refrigerators, lights, and Wi-Fi to laptops, TVs, microwaves, and security devices—through a reliable 48V battery backup system with 6500W rated output and 12000VA peak power.

Essential home loads powered by EASUN SGR-6.5KW-U 120V backup inverter

Power Outages, Rising Bills, and Solar Waste Are Real Problems

Across the U.S., homeowners are dealing with more frequent outages, higher electricity costs, and increased demand for reliable backup power. Storms, grid failures, extreme weather, and utility interruptions can shut down the devices your family depends on every day. Solar panels help, but without the right inverter and battery system, daytime solar power may not be available when you need it most — at night, during outages, or when grid power becomes unstable.

The EASUN SGR-6.5KW-U helps solve these problems by combining solar charging, battery storage control, and pure sine wave backup output in one compact 48V hybrid inverter.

Power Outages

Keep essential home loads running when utility power fails.

Unused Solar Energy

Store daytime solar energy in a battery for evening use and backup situations.

High Utility Dependence

Use solar and battery power more intelligently to reduce reliance on the grid.

Future Expansion Needs

Start with one unit for 120V backup loads and expand later as your system grows.

What Do You Need for Home Backup?

A working backup power system usually includes more than just an inverter. To build a reliable home backup system, you will typically need these core components.

Home backup system components including hybrid inverter 48V battery bank solar panels and professional installation

1. Hybrid Inverter

The inverter converts 48V battery power into usable 120V AC power for home loads. It also manages solar charging, AC charging, output priority, and operating modes.

2. 48V Battery Bank

The battery stores energy for outages, nighttime use, and backup operation. Battery capacity determines how long your loads can run.

3. Solar Panels

Solar panels recharge your battery during the day and help reduce grid dependence. The SGR-6.5KW-U supports up to 9000W total PV input through dual MPPT channels.

4. Professional Installation

Professional installation is recommended for safe wiring, correct system configuration, battery connection, PV string design, and local electrical code compliance.

Reminder: Battery and solar panels are sold separately unless included in a specific bundle.

Built for U.S. 120V Home Backup

The SGR-6.5KW-U is designed for U.S. home backup applications with 120V output from a single unit. This makes it suitable for common household backup loads such as refrigerators, lights, routers, TVs, laptops, microwaves, and small appliances.

9000W Total PV Input

Connect up to PV1 4500W + PV2 4500W = 9000W total PV input.

300Vdc Max PV Open-Circuit Voltage

Supports higher-voltage solar string design within the official manual limits.

90–260Vdc MPPT Range

Helps the inverter track solar production efficiently throughout the day.

Charge While Supporting Loads

Solar input can help charge the battery while supporting connected household loads, depending on available PV power and selected operating mode.

Installation Note: Proper PV string design must follow the official manual limits for voltage, current, wiring, and protection.
