Need help choosing fuse size on solar setup
Hey there, I have a standard solar setup for my camper. I have 2x 100w panels, a 100/30 charge controller and a 3000w inverter.
I am not sure what size of fuse to put on my battery's positive terminal (12v lithium 200ah).
I know that its based on what you actually use in your camper, but doing research I see some results saying to fuse it 100-150 amp (because of the 3000w inverter) or basically anywhere from 20-40amps (I guess based on 12v and not 120v?).
Because of the large discrepancy I am really not sure what I should go with. My gut tells me 30-40a would be fine.
Part of the reason I am so worried is because I had started off with 30amp AGU fuses and I had 3 go. After some research I learned that they aren't good for the type of setup I have. I figured out that 1 or 2 might have blown because I noticed a loose connection on the bus bar but I am still thinking that maybe I chose too low of an amperage?
We really don't use that much electricity in our camper, or at least not anything that will pull a lot of power like kettles, hair dryers etc. We will be charging devices, running a baby monitor and occasionally a vacuum.
Anyways, I was thinking of purchasing a circuit breaker style (Red wolf ones on amazon) instead of an actual fuse but just not sure what amperage I need to buy. Any advice is much appreciated.
