Re: Any gurus on solar panels for charging batteries?
This is what I do at camp. I overkill for fringe cases by using Eight deep-cycle 12V batteries with a 200w solar charger. There's a 1500w inverter for fridge and rare microwave/other-AC needs but you don't want to try to run the fridge from room temp down to cooling temp on batteries, use the generator for that. Also, I have a dual-fuel generator and 300lb of propane in various sized bottles that can store for years. There are gasoline cans that mostly fuel the ATVs/tractors/etc. and cycle through each season since they can go bad but are available in an emergency.
This of course feeds a primary 12V RV and the DC/AC conversion loss isn't as important. All lights converted to LEDs, TVs/DVD/heater-blower/etc. are all 12V. The generator runs maybe 3-4 weeks of the year, mostly during cold/overcast days..SigGendered

Re: Any gurus on solar panels for charging batteries?
I don't know nothing, but I was under the impression that most commonly found Marine batteries aren't truly deep cycles (more of a hybrid).
Diehard RV battery users always recommend 6 volt golf cart batteries. (Trojan rings a bell)

Yes Mr. Ohm I know W=A x V.
But you start throwing mA in the equation it's too much 🙂

I would still keep this in mind.
Also, Lifepo discharge and recharge rates would be better than marine batteries.I don't have a catchy phrase to put here!

Re: Any gurus on solar panels for charging batteries?
I have a gas-only generator - it is at #1 son's house, because I bought a dual-fuel (propane +gas) generator. It cost a couple hundred more, but propane does NOT go bad. You can buy propane tanks all day long on craigslist.
Keep them painted + dry and they last a long long time.
Some lumberyards and RV centers charge FAR less to refill than the big box places.

Re: Any gurus on solar panels for charging batteries?
For a while I saw the prepper types were fond of using lead acid batteries designed for electric golf carts. Not sure if that is still a thing or not.

Re: Any gurus on solar panels for charging batteries?
If anyone has a gasoline generator and would like to convert it to run on propane, there are YouTube videos on how to do that. Apparently it's not hard up to about 12 hp.
I looked into doing that years ago but wound up getting a whole house Generac so I sold the small generator I had.

IANAL. I don't give legal advice. I'm only stating my OPINION.

Re: Any gurus on solar panels for charging batteries?
I'm late to the party, but I'm one of those solar/battery people. I build solar systems and lithium modules for RVs and thought I'd share some of my more fun projects:
480 amp-hour 12.8V rolling case (I have one of these in my RV and under my Ham Radio desk):

One of two 12kWh 51.2V modules for a 50-foot long 5th wheel:

and the twin 10kW inverters pushing out a 240V split phase for the rig:

There are 2kW worth of solar panels on the roof (I don't have a picture unfortunately)
I'll happily answer all things electrical when it comes to solar, batteries, and inverters

Re: Any gurus on solar panels for charging batteries?
If you are knowledgeable, I have some questions for you. I have a large array on my garage roof and would like to get setup for a quick diversion of generated power to a battery bank of some sort in the event of a long term power outage. I am pretty sure that a full bank to power my house would be cost prohibitive and inefficient but I would like enough to keep my stuff charged and maybe run the TV and some LED lights, if possible. Is there an easy, cost effective way to do this?
