Hi all!
I have 20 255 watt 8.39 Imp 30.4 Vmp 37.5 Voc panels, 2 Tristar 60 amp PVM controlers, 16 T105 golf cart batteries and a Magnum 4048 (4kw, 48 volts dc) inverter.
To be honest, large solar systems are new to me question is:
Since the controlers are pvm, it's my understanding (I could have interpreted it wrong) to make the voltage input as close to the output to increase efficiency?
Will 10 banks of 2 panels (60.8 Vmp) each
Be enough voltage to bulk charge a 48vdc battery bank?
If I had MPPT controlers, I would go with
If not, please state your suggestion!
