Schneider MPPT 60-150 has output current but input shows as 0A
i have just installed two Schneiders MPPT 60-150 charge controllers, charging a 430AH 48V battery. Thr battery appears to be charging ok but the readings on the charge controller display are not consistent with meter readings taken with a clamp on meter. The input voltage (112v) is recorded correctly by the charge controller, but the current and power are shown as zero, whereas clamp on meter shows ~7A at 112v. The output readings are also inconsistent. The charge controller readings for current and power as half that recorded at the output by the clamp on mete. I am seeing the same thing with both charge controllers. Any ideas what might be causing this anomaly?
