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
