2000 watts / 14.5 volts = 138 amps which would be 5.2 % of my battery bank amps. Is just getting by good enough? And Is 14.5 volts the lowest an MPPT charge controller will convert higher volts down to for higher amps?
If 5.2% is too close for comfort I could afford adding maybe another 3 or 4 hundred more watts of panels.
2900 watts x 80% = 2320 watts / 14.5 volts = 160 amps.
That would be 6.05 % of battery bank amps. If 5.2% isn't good enough maybe 6.05%?
I calculated for 2 days of no sun because that's really all I need. If needed I have a serious back generator, it's 35 years old but in mint condition, I'm not afraid to fire it up if I have to in order to avoid more than 30 % discharge.
So what do you think. Is that doable? I can always add more panels later when i can afford it.
Again thanks so much for your experiential advice.
