I ordered this Class T fuse from Blue Sea Systems. It has some discoloration on one end. Has it been used? Is it OK to use or should I return it and get another one?

Ok perfect, thanks! Thanks again for the help!

Thank you. Per your advice, and everyone else's, I have come up with this. The 150a fuses are MRBF, the 200a fuse is class T. I oversized the wire between batteries and bus bar, just to be safe. I also added a disconnect heading to the inverter just so I can shut it off completely if I need to...

With my setup (3x 100ah batteries) in 12v configuration and the 2000 watt inverter, what size fuse would you put on each battery between the bus bar? And what size wire would you use from the batteries to the bus bar?

Ok awesome, this helps a lot. Thanks! Yes, the 8 AWG that goes to the trailer goes directly to a fuse for the trailer. The additional items I am adding are just for the inverter.

I have 3 of these. It does have a BMS but it does say "Discharge Current: 100amp. Max Discharging Current: 280 amp (5 second). Should I maybe put a 150amp fuse on each battery then to help protect this?

30 amp. The trailer is currently wired with 8awg. I am not changing that (I will connect 8awg to the existing fuse that powers the trail).

Does anyone have any feedback on the size wire I should use between the batteries and the bus bar?

From reading Will's book, it sounds like I could safely use 2 AWG to go from the batteries to the bus bar, and then use 2/0 to the inverter. Is htis correct?

That makes sense. What would the recommend size wire be if I were to write each battery to the bus bar? I'm assuming I'd still need 2/0 from the busbar to the inverter though.

Hello, I'm swapping out my 2x lead acid batteries on my trailer with 3x Lifepo4 batteries (and adding a shunt/inverter), and I wanted to get some input. The trailer currently has 8 AWG wire going from the battery (positive) to the disconnect. I am wanting to add a 2000 watt inverter. From what...

I've updated this to use bus bars, but this seems overly complicated. Am I doing something wrong here?

I currently have a travel trailer that has 100w of solar and 2 64ah AGM batteries. I am updating this to a total of 400w of solar and 300ah of lifep04. There is existing wiring for the solar panels/charge controller, brake-away switch, and the 12v system in the rv. I will be adding: a shunt...
