I have 4 355w solar panels and 3 315 w solar panels. I have a 40 amp mppt and a 30 amp mppt charge controllers with 100v Max pv voltage.
The distance solar panels to charge controllers is around 15 meters and the distance battery to charge controllers around 1.5 meters.
My battery bank system is 24 volt. The solar panel voltage are around 37 Volts. They are not connected yet.
Out of the 3 315 w solar panels, one is pointed south, the other 2 east. the one pointed south is shaded until 9 AM.They are at 16 degree angle. The other 4 355w are not yet installed.
The system is in the Caribbean.
I have 8 6-volts batteries in 2 parallel strings.
I need help with the wiring of the solar panels (series or parallel) and also the wire gauge.
Thank you in advance for your help!
The specs for the 315 w solar panel are:
Pmax = 315 w Max voltage = 37.4 v Max current = 8.42 A Open Circuit voltage = 45.5 V Short circuit current = 9.12 A Power tolerance = 0~+6w The maximum fuse rating = 15 A
The specs for the 355 w solar panel are:
Rating power at stc(Wp) = 355 w Rating power voltage(Vm) = 37.58 V Rating power current(Im) = 9.45 A Open circuit voltage (Voc) = 46.26 V Short circuit current(Isc) = 9.85 A
