Higher Wire is proud to be offering REC BMS units for our customers! Released in 2023, the 2Q is the latest smart BMS from REC. We use REC BMS for larger builds, especially those that want to take advantage of CAN communication with Victron, SMA and other inverters or charge controllers.

We're offering an all-in-one kit to easily build your own energy storage system using the REC 2Q BMS. It includes the BMS, wiring harness, shunt and 200a contactor. It also includes the wifi module, which is required to program the BMS, as well as an optional CANBus cable for Victron or SMA.
