Batteries

With a battery & proper voltage & power inverter you can about power anything.
Most think small scale like powering lights, TV, fan, etc. But you can go larger like to power a frig or chest freezer.
Even larger you can go 240VAC inverter to power a well pump. And that is a big deal.

If you take one battery & one inverter & look at each as a individual circuit its easier to figure things out. IE: One battery & inverter to power lights & a TV. One battery & inverter for the frig. One battery & inverter for well pump.

And then there's charging the batteries. Backup system for charging the batteries would be using a generator. Solar panels will be your friend. About the only maintenance for solar panels is to keep the face of them clean but even dirty/dusty they will work, just not as efficiently.

Even if you have plenty of fuel for a generator you still don't want to run it all night long. That's when you run off the battery for atleast some lights.

And starting out on a budget you can start by using 12VDC lights & have a 12VDC TV to stay abreast of weather & such.

OK I did check with the local ezgo cart place here I have done business with them before and know the owners they quoted me some batts.
new wet trojan 12 v cart batt $180.00 each
new crown 8 v (337 amp hrs) $ 110.00 wet each
new crown 6v (232 amp hrs) $ 110.00 wet each
all there batts are wet and charged ready to drop in cart and go. from what I have learned it is best to go 4 batts 6v cart/rv type each at least 200 amp hrs x4 = 800 amp hrs put them 2 in parallel = 1 set and 2sets = 1series = 12v output to inverter.
a energy star rated appliance that is rated for 1000kwh per year = 25 amp hrs a day= 16 days use with no recharge maximum.most batts like trojans are good for 300 to 750 cycles so average to 500 cycles or 7 to 10 years max. so 500 cycles at 50% time or 8 days =4000 days divided by 365 days =10 plus years! so usage =time if properly maintained.I am a dummy and not the expert like some here "HH" and others so always ask them nicely for intel and they will lead you straight. I hope this helps put it into laymans terms for all to benefit.

thanks in advance so please for all of us here me included explain why 2 6v batts in parallel are better than 1 12v of same capacity? also if weight like in boat or airplane or whatever was part of equasion would 1 12v be better than 2 6v in lbs. for same output?
thanks

Thanks. ok what about the crown 8v 337 amp hours for the same price as the crown 6v 232 amp hours to get to 48 v with the 8 volt you only need 6 batts. but to get to same 48v with 6v you need 8 batts so have to buy 2 more plus the 8v have more amp/hr rating for more charge?
