62. I don't know the exact answer to your question

Tue Feb 17, 2015, 07:01 PM

Feb 2015

as I am also not very familiar with the new lithium batteries. But, I do know lead acids and I also have a PV system with golf cart batteries for my ham radio station. Most 6VDC golf cart batteries are 220 H-hr at nom 6VDC.

220 A-hr X 6 volts = 1320 w-hr. Times 8 batteries = 10,560 w-hr or 10.5 kW-hr of energy storage capacity.

So that's the number you want to compare a lithium battery pack to. 10.5 kW-hr of storage capacity.

I'd like to know the answer myself but am not interested enough to research it.

People already do use batteries to store the energy they create during the day. cbayer Feb 2015 #11

We also have a bank of golf cart batteries for our photovoltaics. Problem is, if power goes out peacebird Feb 2015 #12

Agree. If your energy source isn't happening, then the batteries are only going to cbayer Feb 2015 #13

Yes, fortunately the panel shed snow pretty quickly. We haven't ever even taken the generator peacebird Feb 2015 #14
