MC4 connectors
I am looking at the 8.8kW unit and am confused by the number of MC4 connectors. I think there are 2 MPPT inputs - so why are there 4 input pairs and not 2 pairs ? Are the extra MC4's just wired in parallel internally ? Is it ok to wire up 2 strings delivering 4kW each ? Thanks !

You can have two identical strings to each MPPT, and watch out for Voc, Vmin and Vmax for each input.
