Good Day All.
I would like to know, if using a Smart Controller 250/100 It states the following in the datasheet:
Taking a look at the "Nominal PV Power, 48V" it states that 5800W should be used. I am using 425W panels and have made 5 strings consisting of 5 series panels each , not exceeding the Voltage rating and not coming close to the input current limitation of 70A(Please confirm I understand the input current correctly or not?).
Adding these I get 425*5=2125W/String thus 2125W*5=10 625W input power into my charge controller, now I know it states a "Nominal PV Power" but my panels configuration does not exceed the 250V or 70A input characteristics. Does this mean that the charge controller will only deliver the rated charging current 70Ax48V=4800W (in ideal conditions)?
My last question is, if I over panel more than 20%(Compensate for shading etc) will that charge controller still only output the rated charge current, will I waste the additional over panels then?
Greetings
