G4 High-Voltage BMS - Base Kit, 12V 4 channel (no CAN)

Nuvation Energy's High-Voltage BMS is designed to manage utility-scale energy storage systems up to 1250 VDC and to meet the external communication requirements of smart grids. This MESA conformant commercial-grade battery management system meets industry-recognized interoperability standards for utility-scale batteries and inverters.

This base kit contains modules and module-wiring to enable you to monitor up to 4 series-connected 12V Lead-Acid monoblocks.

Additional 12V 4 channel add-on Cell Interface Kits are available for systems with more than 4 series-connected 12 V blocks.
