I purchased the 12V 1K MPP Solar unit for my camper, and am having trouble determining fuse/breaker sizing and placement. I will have 160W of panels and a 100AH AGM battery. My understanding is that I need about a 125A fuse on the positive of the battery, but the manual also mentions that the PV array should also be fused, as well as the incoming shore AC. The strange thing is that it mentions a 10A breaker on the incoming AC which seems very small. Not sure why. I definitely would like to be able to easily disconnect PV, so I was going to put a 40A breaker on the red wire. Is this correct?
