I have an MPPT 75/15 and I am getting much less current from my solar than rated.
Right now, in full sun, I read 5.25 amps from my panel open circuit. However, when I plug my solar panel into the MPPT 75/15, I am only getting 2.9 to 3.0 amps.
This happens 100% of the time, even with my other solar panels on trips out to the desert (full sun).
I understand that current will taper as the battery reaches full capacity, but this is even at the start of a bulk cycle in the morning.
I checked the maximum charge current in the settings and it is right there at 15 amps factory default.
Any help is appreciated.
Thanks,
Chris
