ECO-WORTHY 48V 5120Wh Home Backup Power Kit with 5000W Inverter

This ECO-WORTHY kit combines a 51.2V (48V-class) 100Ah LiFePO4 server rack battery with a 5000W inverter. Together they offer 5,120Wh of storage and up to 5,000W of output. ECO-WORTHY presents it as a way to keep basic household appliances running during a power outage, and as a base for a larger solar system.

What 5,120Wh and 5,000W mean

Watt-hours measure how much energy the battery stores. Watts measure how much power can be drawn at once. 5,120Wh could in principle supply a 500W load for roughly ten hours, with real-world runtime lower because of conversion losses. The 5,000W inverter sets the ceiling for how many appliances can run together, and the listing gives a peak of 10,000W for short surges such as motor start-up.

The battery

The battery uses LiFePO4 (lithium iron phosphate) cells, which ECO-WORTHY describes as Grade A. This chemistry is widely used in home storage. It is generally valued for a long cycle life and for stable behaviour.

It has CAN and RS485 communication ports and several protocols, so it can talk to compatible solar inverters, and built-in Bluetooth and Wi-Fi allow monitoring in the ECO-WORTHY app.

The 3-in-1 inverter

The inverter combines three parts: a 5000W pure sine wave inverter, a 100A MPPT solar charge controller and a battery charger of up to 100A. The listed figures are:

• PV input range of 120 to 500V DC;
• rated output of 120V, with 5000W rated and 10,000W peak;
• recommended charging voltage of 57.6V and charging current of 0.5C (50A);
• charging from AC at 40A, from PV at 100A, or hybrid at 100A.

Pure sine wave output is the cleanest form of AC power and suits sensitive electronics.

Safety certifications

ECO-WORTHY says the battery and inverter passed UL1973 and UL1741 testing by Intertek and meet California Energy Commission standards. These are North American standards for stationary batteries and for inverters. Certifications don't replace correct installation, so follow the manual and your local electrical codes, and consider a qualified electrician.

Expanding later

Up to six inverters can be paralleled for up to 30kW AC output. A single inverter gives 120V, and two or more allow 120V, 208V or 240V output. Up to 32 batteries can be connected, for a maximum of 163.84kWh.

What's in the box

The kit has one 5000W off-grid inverter, one 51.2V 100Ah battery and the necessary accessories. For safety reasons, ECO-WORTHY says the items ship separately. The unit's listed weight is 130 lb (about 59 kg), and its dimensions are about 22.1 x 19.0 x 5.6 inches.

Who it suits

It suits owners who want backup for essentials such as lighting, a fridge and networking, or who plan a solar system they can grow. It is not a plug-and-play portable power station.

What to check before you buy

• Your loads: add up the running and start-up watts of what you want to power.
• Installation: a battery and inverter of this size normally needs proper wiring, protection devices and, in many areas, a permit.
• Rack or shelf space: the unit is rack-style and weighs 130 lb.
• Solar input: if you add panels, check that their voltage fits the 120 to 500V range.
• Compatibility: confirm which inverters the battery's protocols work with.
• Delivery: the parts ship separately.
