Mixing solar panels

It is all a compromise and scenario dependent, but it was no good with a 120v only fridge in our case for off-grid and no generator time for more than a few days. It was too much of a nail-biter if we got enough sun and the weather keeps changing around here.

Takes the fun out of the whole thing if all you do is worry about the fridge and if the weatherman is lying again :( . It was so great to get back to having a propane fridge.

OTOH that can't really be run on 120v off grid, taking 34 amps via inverter while it is cycled to on. So it stays on propane while off-grid. Getting more propane is easy in our situation, so that's that.

We toodle around sight- seeing a lot so it is no problem shopping for more food to re-stock instead of having more fridge space.

Everything is a compromise for what suits your own situation of course.

Agreed, I am having the same worry with the propane. I've had a couple of experiences where we came back to the RV and found the fridge off due to propane running out. We've purchased a large tract of land where we'll eventually build a home, but for the time being we'll park the RV there, and it's far enough away (2hr drive) that visits need to be planned. I realize I'm using a sledgehammer to drive a nail (i.e. we could shut off the fridge and restart when back on site, etc), but that's just how my brain is wired! It's also good practice for our future build which will be completely off-grid.

phemens your getting near the same amount of solar and have an additional 100ah of lfp batteries than my setup.

Late spring/ summer/ fall I'll switch my Norcold 821 over to electric (30ah) around 8am and back to propane 6-8pm doing this I extend my 30# tank by 5-7 days and gives you the flexibility of dual power use.

With Lfp charging faster and not going through a long absorb stage allows this to be very convenient with the rv fridges.
