High Voltage BMS 70S224V 100A BMS Battery Management System For Small Lithium Battery ESS UPS Solar Energy Storage

High Voltage BMS 70S224V 100A BMS Battery Management System For Small Lithium Battery ESS UPS Solar Energy Storage

The HV 70S 224V 100A BMS is designed for home energy storage systems and can be effectively combined with an inverter to create an efficient setup. The BMS, which stands for Battery Management System, typically collaborates with other devices such as inverters, chargers, UPS, or PCS to ensure optimal performance. In certain cases, specific communication protocols may be necessary to facilitate communication between the master BMS and other devices. By working in tandem, the BMS and the inverter enable features like peak shaving and valley filling, effectively managing energy storage.
A complete set of the HV 70S 224V 100A BMS includes the following components:
Master BMS (Model: RBMS09-S70S-100A): This serves as the central control unit for the system. It comes with its corresponding wire accessories, which consist of 6p temperature sensing wires and 16p voltage sensing wires.
Additionally, there are two variations available for the integrated BMS. One is a standalone model, while the other can be paralleled with other systems, albeit at a slightly higher cost.
