How to build up your high voltage battery systems for ESS?

it’s very easy to build up your BESS with GCE high voltage BMS, the integratred BMS is designed for 30S to 75S, low capacity cells for LFP(lifepo4),NMC, LTO,Lead carbon…

Our integrated BMS has master and slave structure and combined these two types of BMS PCBS in one machine. You can connect your each cells with provided wire harness to our integrated high voltage BMS in order.Our integrated BMS also has 4 tem sensors for each 15S lithium battery modules. We provide rich communication ports(Rs485,CAN,dry contact) to meet different requirement for energy storange or UPS users. We also have different types of integrated BMS to meet Off-grid ESS application. 3.5inch touch screen will display all informations after parameters setting!

30S50A integrated bms


BMS integrated machine components are composed of BMS main control board, BMU sampling board, high voltage board, switching power supply, Hall sensor, DC contactor, micro switch, power terminal, structural box and wiring harness, etc.; the characteristic is that the main control board Integrate with sampling board and other power devices to keep the system as a secondary architecture. It has the characteristics of compact structure, flexible installation and low cost, and is suitable for integrated installation with small capacity batteries. The BMS integrated machine component is mainly suitable for the charge and discharge management of lithium iron phosphate batteries (LFP). If you need to modify the parameters with other batteries, please contact our company for confirmation.
