Dear guys,
I have 12 solar panels. Each panel Basic specs as below:-
Nominal output (Pmpp) 250
Voltage at Pmax (Vmpp) 30.5
Current at Pmax (Impp) 8.2
Open circuit voltage (Voc) 37.5
Short circuit current (Isc) 8.7
I am willing to buy an inverter with built in MPPT charge controller. Specs of the inverter as below:-
PV INPUT (DC)
Nominal DC Voltage / Maximum DC Voltage 360 VDC / 500 VDC
Start-up Voltage / Initial Feeding Voltage 116 VDC / 150 VDC
MPP Voltage Range 250 VDC ~ 450 VDC
Maximum Input Current 1 / 1 x 13 A
GRID OUTPUT (AC)
Nominal Output Voltage 208/220/230/240 VAC
Output Voltage Range 184 - 264.5 VAC
Nominal Output Current 13.1 A*
BATTERY & CHARGER
Nominal DC Voltage 48 VDC
Maximum Charging Current 25A
So here comes the question:-
I need to know how to wire the panels in series or parallel configuration or series/parallel combination so as to remain in the specifications of the inverter?
Please note I will have four batteries installed of 200AH each connected in series.
Any help would be highly appreciated
