Self resetting over current devices often cause as many problems as they solve . If a piece of equipment faults the breaker keeps trying to reset often until it destroy itself or the piece of equipment. Automatic resetting circuit breakers are especially dangerous when used with rotating or moving equipment . Circuit breakers are electric/mechanical devices and often corrode internally changing the trip point and are supposed to be exercised on a regular basis Fuses may be low tech but they consistently work. I agree with Mr. Miller start with a good converter and eliminate a lot of problems

Add to Steves comments that regular switch type AC circuit breakers also change value as they age, especially if they are used as on/off switches on a regular basis. New breakers for most panels are in the under $10 range and new ones are always a good idea on older panels.

Thanks for the additional info. I checked out installation for Bob's PD 4045 on the net last night. Yikes...I hope and can do that--seems complicated. So forewarning Bob. You may be tapped for LOTS of questions.

Perhaps the simple controllers, mine was designed for both. It also has a USB connection to download data to a computer. I can keep track of charging and loads for up to a year.

Steve, it's standard practice to use self-resetting circuit breakers in RVs on the circuits we have been discussing. These are specifically designed for vehicles with DC applications. My Escape 19' has several of them wired in from the factory. I will bet your Casita has one between the battery and the distribution panel. If you think it is dangerous and will corrode over time maybe you should remove it.
