This remote meter is provided with a mounting plate and 100 ft. of cable. It is identical to the TS-M-2 solar energy meter except that the TS-RM-2 version can be mounted at some distance from the controller. The meter will display a great deal of information about the TriStar MPPT controller and the operation of your system. In addition, the solar energy meter enables manual functions and controller diagnostics. These capabilities will increase your confidence that the system is working properly and will help you to improve system reliability, battery life, and system performance. This solar energy meter is to be used with either the TriStar MPPT 45, or TriStar MPPT 60 controllers.
