    Solar panel battery charging through a circuit-breaker

    I've bought a 140 watt solar setup from a highly reputable outlet (eBay) and am planning on using it to keep my aux battery charged on a trip. I already have a 12v outlet on the rear of the vehicle, for running the fridge in the trailer (not taking the trailer this trip). This outlet has and Anderson plug and is connected to the aux battery via one of those inline circuit-breakers. My plan is to attach an Anderson plug on the solar panel and plug it straight into this outlet on the back of the car. My question is, will the circuit-breaker cause me any problems and am I better off by-passing it for this purpose, or can I pass charging current back through the breaker without any issues.

    Hi POD and as long as it is a circuit breaker, then you will have no problems.

    Your panel will put out no more than about 6 amps but the circuit breaker should be at least 30 amps, so no conflict there.

    You do have a solar regulator on the panel?

    Yes, folding panel complete with charge regulator. Amazing how much these have come down in price, paid $900 for an 80w system whilst on a trip 5 years ago, sold it on eBay when we got home and almost got the full price back. Now $200 for a 140w system.

    Not necessary thanks Damien, there's already a breaker in the circuit, I was just wondering whether it's presence was going to be a problem. I'll PM you about the parts.
