100% electrical conversion?

I was just saying in another thread that we could do more with the solar, it's a neat idea but I can't justify the expense. It would be 10 years before I burnt enough propane to pay for the upgrades. The tanks would still have to stay for the furnace and cloudy weather.

Hi,

The water heater would use about 8,800 Btu's per hour, or about 2 KW per day to replace just one hour of propane run time.

The refrigerator can be replaced with a high efficiency electric refrigerator, and then install a pure sign wave inverter to handle the high torque of the compressor, and you can save running that load on propane. Yet even that load is only about 10 gallons of propane in around 6 weeks of camping. I used to fill with about 15 gallons of propane every 6 - 7 weeks while full time in the RV, and mainly using just the refrigerator and water heater in the summertime. Winter I would use a lot more propane to heat the RV, depending on where I was located.

I have a 415 rated watt solar system, and it charged the batteries only. I did not use the inverter to power the refrigerator or water heater.

And what were the reasons given in the posts that you read?

Just keep in mind that 30AMPS is at the 120VAC level. It will be 300AMPS at the 12.3VDC level

A typical solar panel only puts out 5AMPS at 12.3VDC so you will need a barn full of panels to get to 300AMPS only when in HIGH SUN. You will need a bunch of batteries to store enough power to get you thru the night when the sun goes down...

Pretty big task...

No, solar to heat rv alone and/or heat rv water is not practical. You might make some of your wishes work in a stick house where the sun heats water directly as opposed to photovoltaic panels.
