Re: Newbie Q

An 832 amp battery bank can be charged at a rate of 10-13% which would be 82 to 106 amps. 108 amps x 65 volts to charge the bank = 7030 watts. @pss, I would typically use 55V, 82*55=4,510W or 106@55=5,830. I suspect @pss is derating the STC power output of the panels/charge controller by 23% - so i...

Re: New guy here, please help me understand what I have

../.. this is a completely off-grid situation. That does change things, the key issue is that without any solar charging while you are away the batteries will self discharge. Being 7 years old, they have done well if you are still able to get power for a couple of days use. Make sure the inverter i...

Re: New guy here, please help me understand what I have

I think the AC in of the inverter will be connected to the Grid so as to keep the batteries fully charged. When the grid goes down then the battery bank supplies the power. When the battery bank gets low the inverter bypass switch is manually switched to isolate the grid input and allow the generato...

Re: How to use both generator and solar to charge batteries

I would ditch the wind turbine and spend the equivalent money on extra solar capacity.
