RV batteries, generators and solar panels?

I have a question that is probably so basic that is why nobody has covered it. Everytime I mention generators being loud and not campground friendly they boast that the new models are quieter...quieter maybe but noise is noise non-the less and it's not a road I'm willing to go down...ever!



That leaves solar and battery banks right? I currently have 2 batteries and starting comparing prices on solar and it's still quite expensive. Up here in the north a decent solar setup will still run you in excess of $800 CDN. A sealed battery for my RV is just about $100 so I'm wondering how much bang for my buck I'll be getting by adding new batteries? How many batteries are overkill...is there such a thing as too many? I understand the virtues of solar but what I don't have is information about battery banks?

You said you are not looking for information about a generator but looks like everyone wants to offer generator info anyway.. Too funny..



What is over kill for a battery bank? The easy answer is anything over what you need is over kill. Get a kil-a-watt meter (40 USD) and find out how many watts you normally use in 24 hours.. If you are using a 12 volt battery bank divide that wattage number by 12 volts. This will give you how many AH's you use. You NEVER EVER want to run a battery bank lower then 50% discharged. So double the above number and you will have your battery bank size in amp hours.



Now that you know how many AH's in batteries you have mutliply that number by .05 and you have the Amps you need in solar modules.



Example.. If you have a 450 AH battery bank (4 Trojan T-105)



450 * .05 = 22.5 amps at 12 volts.



Now amps times volts gives watts so



22.5 * 12 = 270 watts in modules minium.

well about the generators you can modify the mufflers by adding extra mufflers or make one of your own and adapt it and solars are getting pretty good but of course they are expensive and if they are protected during storage and traveling they can last a long time as for batteries you will have to calculate the load needed to run for a certain numbers of hours before you need to recharge them(watts x hours = watthour capacity)some have what you call amperagehour rating they are convertable like 12Volts x 30 amps =360 watts
get a different muffler to quite the motor, and 3 1000 amp truck batteries will power your lights for 3 days,as long as you don't use a microwave.
