The DC-GFP device monitors current flowing between battery negative and earth ground and will trip
when more than ½ amp is present. There should be no current flowing in this circuit under normal
circumstances.
In the event your DC-GFP trips, it is usually on a new installation. One of two things is happening.
1: There is an actual ground fault in the wiring, or 2: there is an excess of current flowing through the
large 63 or 80 amp breaker. Be sure to check your wiring! Refer to the wiring diagrams in these
instructions.
80 amp panel mount DC-GFP ready
for the high current wires.
63 amp din rail DC-GFP wired with a
63 amp PV disconnect and a 63 amp

Single DC-GFP Wiring.
The MidNite Solar Classic charge
controller has the DC-GFP plus arc
detection built in and does not require
