Circuit breaker vs fuse

galladanb · Apr 12, 2017

Cool! Holders ordered with 150 Amp fuses.
The holders came in a two for pack, So I will use one holder and a 150 Amp fuse, and have a spare...
I will use the second holder for the DC distribution system...
I also ordered a two pac of 100Amp fuses, one for the DC system with a spare fuse... ( That's not too big is it?)

The solar kit had a 20 amp (ANL) fuse and a 10Amp (I believe) inline fuse...

So, now all I need is to find a switch for the panels, and cables of course.
I will order the cables after the holders get here...

One thing at a time it looks like, LOL!

Such Fun!!!

Bank fuse is best within 7" of positive terminal. Switch next where you can get to it quickly if needed.

Just put MC4s for solar panel disconnect, not like you need to do that frequently. Or just position controller so easy to detach there.

By the MC4's, those are the connectors that came with the panels, right?
I looked at them and I'm not sure how easily they connect or disconnect...?

The switch for the panels may not ever be needed, but I may feel better knowing that I can disconnect any power source for future maintainace issues, etc...

Then use a decent quality switch designed for high-amp DC for all the panels' current at once, like at the battery bank.

Smallest Blue Sea should be enough.

I think most people just pull the fuse when they need to disconnect the panels.

You need a special tool to disconnect MC4s. It's not expensive.
