50 KWh Lithium Battery

Energy Storage System

This 50 KWh lithium battery energy storage system is an all-in-one solar and storage solution which integrates the inverter, battery charger, UPS, and battery enclosure into a pre-wired modular system for easier and faster installation.


Ease of Installation

The ESS is pre-wired and factory tested to enable quick installation. It only takes 5 minutes to connect the system to your customer’s home internet. This modular system is expandable with battery storage to suit the customer’s needs.

Battery Management System (BMS) has protection functions including over-discharge, over-charge, over-current, and high/low temperature.


The BMS system can automatically manage charge and discharge state, balance the current, and voltage of each cell.

The system can automatically switch to back-up mode in less than 0.01s (UPS level).

Working temperature range is from 32F to 122F (0C to 50C), with excellent discharge performance and cycle life.


Design for home appliances, easy to install and handle.
