Forgive me for my ignorance but I am a retired working man and have little knowledge of these things. I have a grid tied array on my roof and I want to know if it would be feasible to add at least some battery storage capabilities to it. I have 72 panels on two Solar Edge inverters. The array seems to be divided into quadrants.
Specs are:
Panels:
72 270W, 8.69 Amp, 38 VOC, Pmax (whatever that is) 31.1V
Inverter(s):
Solar Edge SE7600A-US
Max DC Power 9300W
Max DC Volts 500 V
Max Input Current 23.5 Amps
One quadrant would be 18 panels and I did this math:
18 Panels in series at 38V/ea would equal 684V, more than the inverters are rated for. At 31.1V it comes to 559.8. I'm guessing that the inverters are underrated because max voltage will never be produced. Am I on the right track?
I have four (4) sets of wires coming into the inverter(s). Is there any reason I can't tap into those leads and feed a charge controller then a battery setup? Can I just put a switch inline to facilitate just switching it over to charge the batteries?
Thanks for any and all help,
Mark
