MidNite Solar MNWBJR Whiz Bang JR. Current Sense Module;

The Whiz Bang Jr is a current sense module that attaches to the standard 50mv / 500A Shunt and wires into the Classic and KID Charge controllers to give Amperage readings from the shunt. This allows for EndAmps to function based on System amps or Classic amps. To use the Whizbang jr (MNWBjr) with any of the Classic Lites, you will either need the local app or an MNGP.
