Power Inverter

[skeet]

Depends on the amount of wattage you would use during the day..Ain't no free lunch as they say...to stay even at 750 watts at least 3 batteries..unless you add more solar cells..Battery size adds to the equation..condition also..Just breaking even would not work for use in the evening too.. That is why solar and "green energy" is so expensive.. You have to over engineer for unforseen usage or unforseen low charge times..usually by 50% up to 100% more than average usage..small systems even more. I know a guy that thought running a battery charger off the inverter would keep the batteries charged..won't work. As I said..no free lunch...If that would work we'd all have free energy. LOL Law of conservation of energy is always at work..Physics ya know
