This control interfaces with the Victron range of MPPT Charge Controllers and gives access to performance information. It can also be used to program the charge controller. A VE Direct cable (not included) is required to make the connection to the MPPT controller. The MPPT Control lets you see the status and setup all MPPTs that use a VE.Direct communications port. The new MPPT Control is mounted in the same housing as the BMV energy monitor
