Check certificates for your market
The safety certificates shown on Eco-Worthy's US and Canadian pages are for those markets. For a UK install, ask the seller which standards the UK version meets, and make sure your installer is happy to sign it off.

Who is Eco-Worthy
Eco-Worthy is a solar and battery brand that sells mainly direct to consumers. It runs separate web stores for several countries, including a UK store, and its products also appear on marketplaces such as AliExpress. It is best known for low-priced server rack batteries, all-in-one inverters and bundled off-grid solar kits.
We could not verify details such as its founding date or headquarters from independent sources, so we do not state them here. What can be checked is the product range and the listings, which is what this page covers.
The Eco-Worthy product range
The core battery is the 48V (51.2V) 100Ah server rack battery, 5.12 kWh each, sold in a 3U form factor with Bluetooth and Wi-Fi and a built-in battery management system. It communicates with common all-in-one inverters over CAN or RS485. Six-slot rack bundles of 30.72 kWh are also listed, and newer versions carry names such as Cubix 100 and Cubix 100 Pro.
Around the battery, Eco-Worthy sells 48V all-in-one inverters, solar panels and ready-made kits. These are aimed at sheds, workshops, off-grid cabins and DIY builds as much as ordinary grid-tied homes.

Key technology behind Eco-Worthy batteries
The batteries use LiFePO4 cells in a standard 19-inch rack format with an internal BMS, and the app connects over Bluetooth or Wi-Fi so you can see state of charge. Several communication ports let the battery talk to an inverter, and units can be paralleled to add capacity.
Newer versions advertise a low-temperature charging function. As with any low-voltage battery, safe use depends on correct cable sizing and an inverter that supports the battery's communication, which is why a qualified installer matters.
Strengths and limitations
Eco-Worthy competes mainly on price and availability. Here is a balanced picture.
Strengths
- Low entry price per kWh compared with installer-led systems, which is the main reason people look at it
- Standard 3U rack format and common inverter protocols, so it works with many all-in-one inverters
- Bundles of inverter, battery and solar panels for DIY and off-grid builds
- A UK web store, so UK buyers are not limited to marketplace listings
Worth checking before you buy
- Warranty terms can differ by market and seller, so get the exact term and claim process in writing
- Safety certifications we found were for North American versions; confirm UK-relevant standards
- Support and returns can depend on whether you bought from the brand's own store or a marketplace
- Not a plug-in product. In Great Britain, rules that took effect on 27 August 2026 allow plug-in solar panel kits of up to 800W to be self-installed, but they explicitly exclude plug-in batteries. A battery like this still needs fitting under the normal UK electrical and battery-storage rules.
Where Eco-Worthy fits the market
Eco-Worthy sits in the same low-cost rack battery group as Fogstar, Dyness and Pylontech. Compared with Fogstar, which holds stock in the UK, Eco-Worthy's strength is price and a wide range of bundles. For a fully installed, accountable system, installer-led brands such as Sunsynk are simpler.

Common questions about Eco-Worthy
What does Eco-Worthy make and sell?
Eco-Worthy sells 48V LiFePO4 server rack batteries of 5.12 kWh, all-in-one hybrid inverters, solar panels and complete off-grid or backup kits.
Is Eco-Worthy a UK company?
No source we checked shows it as a UK manufacturer. It runs a UK web store and sells through marketplaces such as AliExpress, so treat it as an overseas brand with UK sales channels and check who handles warranty claims.
Can I install an Eco-Worthy battery myself?
Connecting a 48V battery and inverter to a home is work for a qualified electrician, and grid-connected systems must be notified to your network operator. Off-grid builds still need correct fusing and cable sizing.
Does Eco-Worthy work with my inverter?
Eco-Worthy lists CAN and RS485 communication for popular all-in-one inverters. Compatibility depends on the exact inverter model and firmware, so confirm it with the seller before ordering.
What warranty does Eco-Worthy give?
Eco-Worthy and dealers list 10 years for the Cubix 100 Pro and V3 rack batteries, but terms can differ by market and seller. Ask the UK store for the written warranty terms for the exact model and check how claims are handled.
Is it safe to buy from a marketplace listing?
Marketplace listings can mean different support and returns from the brand's own store. Compare the seller, the warranty terms and who handles a claim before you buy, and keep your proof of purchase.
