Putting in my first solar system. This will be an off grid system about 3kw. I have the battery system together (i'm in the lithium business) and just purchased a mpp 3048 lv-mk inverter from Ian. So now panels. Looking at doing a 3s2p config. There is a local supplier and I'm looking at the Heliene 490w panels( 132HC M10 SL 490) . The voltages all seem right but the 6 panels have the ability, at full output, to exceed the controllers max current. Will the controller just limit the current to its max or will the slightly higher amps damage the controller. I obviously could just use 4 panels but would like to use 6. Just want to make sure I won't be damaging anything.
Update: wasn't paying attention on this. 3s2p would be only 20a current, so that should be fine.
