AH usage

Can anyone tell me how many AH are being used when the fridg is on gas: and mandatory electronics are on.

The refridge running on gas will use almost no electricity. I think mine used about 0.5 amps. So, call it 12 AH over a 24 hour period.
Regarding necessary electronics, that is highly variable as everyone has a different opinion of what is necessary. On my trailer, if I watch a bit of TV (inverter), run the water pump occasionally, run the water heater on gas, turn on a few LED lights when needed, I am looking at about 25AH from sundown to whenever we wake up. If I need to run the furnace that might increase to 40AH or so.

It will tell you in the manuals you received with your RV

Last fall I stayed in a full timer spot for three nights. It had an electric meter and that usage was 94 kwh for the 3 days. We had everything on tv, DVR, refer, electric heater (cold nights under 32 degrees), lights in the trailer and cell phone charger. That is 94,000 watts over 3 days. When we go to solar that info tells me I need a large battery bank of 800 amp hours of useable power. The weight of the battery's will be 800 LBS.

And remember you don't want to discharge lead-acids much past 50%...

You're going to need over 5kw of solar. That's what I have on my roof and on a **Very** good day, do I only top 35kwh.

Be very wary of comparing shore power consumption to battery draw.
The processes of converting 110V AC down to 12V DC, or "inverting" battery 12V back to 110V, are not very efficient, so it's not a direct relationship. You'd have to know how much power is being wasted in the conversion, before you can draw a comparison.

I have just started to look into solar but wow Panasonic has new generation panels that do 330 watts. It looks like 48 watts of battery is what the panels do. Magnum Pure sine wave inverter owns this space.

Please share anything on solar or battery banks.

Panasonics are good cells. I have SolarWorlds and have been happy with them for the past 3 years. It's hard to believe how tough they are... We've had a few decent hail storms with up-to golf-ball sized stones and they're just as dent-free as the day they arrived.

I would recommend looking into solutions that allow independent voltages per panel. Not sure how familiar you are with PV but, without optimizers on each panel, if one panel becomes shaded, it will cause the nominal array voltage to decrease.
