Features

Flexible Customization

Need your own brand or a specific setup? We accept OEM & ODM requirements and customized orders including logo branding, touchscreen, languages, colors, packaging, paralleled function, WIFI, Bluetooth, APP, and custom designed for BMS like PACE, JBD, TDT, JK and the other preferred brands, custom-made battery packs with preferred lithium cells like CATL, EVE, GOTION, CORNEX, HITHIUM, WELION, REPT, GREATPOWER, BYD…etc.

Easy Installation & Capacity Expansion

The battery supports floor-mounted installation and can be re-located when needed. Want more energy storage with a larger battery capacity later? You can connect multiple battery units in parallel, with support for up to 15 units, making system expansion much easier.

Smart Monitoring

Keep an eye on your battery without constantly checking it. Built-in WiFi and Bluetooth, together with the APP and BMS, let you monitor important battery information and system status remotely and more conveniently just on your mobile phone or computer.

Long Service Life

Nobody wants to replace a battery every few years. With up to 8,000 charge-discharge cycles at 80% DOD, the battery can last more than 10 years of long-term use under suitable operating conditions.

5-Year Warranty

We provide a 5-year warranty to give distributors, installers, EPC projects, and end users more confidence when choosing our lithium battery for solar energy storage projects.

Ready for Different Climates

With extreme climate tolerance, no matter the lithium battery is installed in a hot region like Dubai or relatively in a cold environment like Russia, it can operate properly within a working temperature range from –20°C to 40°C.

Built-In BMS Protection

Safety comes first. The advanced BMS provides over 20 protection and monitoring functions, helping manage charging, discharging, voltage, current and other key battery conditions during everyday operation.

High Round-Trip Efficiency

Less energy wasted means more usable power for your solar energy storage system. With round-trip efficiency of up to 99%, the battery can make better use of stored solar energy and electricity when charging and discharging.

Qualified Safety Certificates

For customers who care about compliance and transportation, the lithium battery can be supplied with relevant safety documentation and certifications, including UN38.3, MSDS, IEC 62619, IEC 62040, and IEC 61000, depending on the specific model and configuration.
