100 watt Solar decision
I'm planning on Boondocking for a few months, plan to run my phone, some lights and hopefully my refrigerator on a 100 watt solar panel charging the Travel Trailer Battery for a short time job. Aft...

Whats the math on the fuse? I can actually change my order. I was going on 30A fuse based from the charge controller being 30 amps.
Brettmm92,
The converter often has 2 or sometimes 3 30 amp fuses on the DC side. Those are 'reverse polarity' fuses. The wire they feed into will have either an "automatic" circuit breaker or another fuse very near the battery bank.

I got a really cheap cobra 400 watt modified sine inverter and want to use it safely.
While a 30 amp fuse with #10 wire would work (360 watts), it would be much better to move to #8 wire with a 40 amp fuse would be better (480 watts). As a bonus there would be much lower voltage drop to the inverter, and the costs of moving from #10 to #8 are not that big.

Maybe I will keep the solar, but I'm thinking about enjoying the solar setup until late in the year. Without it the solar and my current plans I just wouldn't have electricity but me needing to be accessed by phone provoked the whole solar thing. And I actually don't have an RV battery because I junked it (recycled) after realizing it was dead.
By all means--get some solar and if nothing else works, lay it on the ground. 200 watts as a minimum.
ps I loved my cobra msw inverter.
