You need to install the fuse as closed to the positive terminal post as you can. Wires can burn and break, If the red line breaks and then touches ground somewhere it can catch fire. Even the Negative wire, if it breaks and touches the positive terminal post (much more unlikely but possible) it can catch fire. You could install a fuse on each post to be safe, but definitely on the positive post and as close to the post as you can get it. Preferably right onto the post.
You should also run a ground off the inverter it's self . But always put a fuse in the positive side ..I've found over many years of trucking these little black and copper fuses NAPA sells does the trick ..,I'd never seen any of you RV dudes do a video on fusing your inverters
I'm tired, sickly, and haven't been........ Well, I'll try and explain fuse and inverter. Take it with a grain of salt. W=AxV W/V=A Say you purchased a 500w continuous inverter and need a fuse. 500w/13.6(vehicle volts)=36.76amps. So, if the inverter is maxed out, the inverter will be tasked to draw 36.76amps from your power supply, to supply 500 watts, PLUS what it needs to work. Which means a 40 amp fuse MINIMUM. Now, some features of a 500w inverter might say it can handle an added 500w short surge. A 40amp fuse might pop on that spike, yet it might not. IDK... I've read someone stated add 50% to the fuse. So, the 40amp fuse becomes 60amp (60x13.6=816). So, the inverter can surge to 816 watts...giving a little leeway for the fuse. EDIT: My experience is that a fuse will usually pop between +40% and 50% of its rated capacity. So a 40 amp fuse will pop around or below the 60 amp mark. If I required a 217 amp fuse, I'd get the closest fuse, like a 220 amp fuse. POP QUIZ. If my theory is correct and I'm not too sickly, which fuse for the following: 1000 watt inverter continuous with 1,500 surge. 2000 watt inverter continuous with 4,000 surge.

Thank you for posting this information. I was hoping this video would show the actual install.
We know what size the fuse is, what size is the inverter?

good stuff !!
You did not show the installation? I needed that the most. Do I need an extra wire??
Pretty simple just follow your instructions if your not comfortable doing wiring I’d get some help. You need to ground it

POP QUIZ.
