Today my panels produced a consistent 1600 watts.
The array is 2S-4P (250 watt panels 40 volts for a 24 volt battery system)
The amperage from the Combiner box to the MPPT (Victron 150/60) was around 30 amps and the Cerbo/VRM showed a peak of 33 amps. I checked the wires from the combiner to the MPPT and they were warm to the touch. The wires are 10 awg.
Now, the wires from the MPPT to the batteries were slightly warm too. They are 2 awg. The amperage from the MPPT to the batteries was about 45 amps (also used a clamp-on ammeter). I'm not so concerned about the wires from the MPPT to the batteries- they can handle it.
I am concerned about the wires from the combiner box to the MPPT. What gauge should I increase them to, if at all?
Thanks.
