Features:
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 that include over-discharge, over-charge, over-current, and high/low temperature.
The BMS system can automatically manage the charge and discharge state to balance the current and voltage of each cell.
The system can automatically switch to backup mode in less than 0.01s (UPS level).
The working temperature range is 32F to 122F (0C to 50C), with excellent discharge performance and cycle life.
Design for home appliances, easy to install and handle.
