I want to get 4x 150W Newpowa mono panels for my van (due to size constraints this is my best option). Theoretically I need a 50 amp MPPT. Considering the efficiency of panels and the fact its unlikely I'll ever get an ideal sun angle since they'll be fixed flat to the roof, if they're 70% efficient (i.e. put out 105W each) I'd only need a 35 amp MPPT.
In one of Will's videos he compares 4x 100 amp panels and he gets an output of 57-70 watts under quite ideal conditions (57-70% efficient).
Can I realistically buy a 40 amp MPPT to save myself a couple of hundred dollars and not break anything?
