I built my own little solar power pack https://diysolarforum.com/threads/diy-solar-power-pack.8847/ and recently added a 12 volt fuse panel to it. So as you can imagine the primary 12 volt positive comes into the fuse panel and I have a single fuse for the 12 volt outlets (one cigarette outlet and one dual USB charge port).
Prior to adding the fuse panel I could plug my 300 watt inverter into the cigarette outlet and it would run with no problem. I put a 10 amp fuse on the line that connects to the power ports and as soon as I plugged the inverter in (even with the inverter turned off) it blew the fuse. Ok, so I bumped the fuse up to 15 amp and same thing, the fuse blew as soon as I plugged in the inverter.
I'm hesitant to just keep bumping up the fuse size so wondering how (if?) I can find out what size fuse I should have on this circuit to keep things safe and make sure the inverter works?
