I had a meltdown and could have burned my building down.

Hopefully I will have everything done tonight so I can take some pics of it all without it looking so bad. I really like the enclosure I went with for the massive midnite solar breaker.
 
For my DIY batteries I use a Victron Lynx Power In converted to a Distributor with Mega Fuses for a 48v system. I assume this is an OK system/fuse for my EVE 105 100amp (surge) packs. One mega fuse per pack.

Also a great option for the OP, but I like breakers better for the odd occasion you want to temporarily isolate something. Also bare in mind the inverter already has a breaker for the total battery input.

@Quattrohead I'm going to be updating my packs very soon, at that time I I'm going to move to double pole breakers, think you posted them. Will also keep the Lynx, great busbar and shunt attachment.

Getting my packs out of open air into an aluminum fully enclosed (with lid) box. Decrease the blast radius if something goes wrong with them. Will DIN rail mount those brakers on outside of box.
 
Yes I had replied to crowz regarding PV disconnects and this got lost in translation. For me, MNEDC250 fully rated DC breakers are the way to go but around $90 when not on clearance, not a lot more than a class t fuse and holder, however you have to figure out an enclosure for them.

I highly recommend the midnite busbar enclosures for mounting. The 1000A one I have is probably too big for most people but they have a new smaller 500A one.
 
I like Midnite (Carling Tech) breakers and a class T fuse .

(Ideally the wire lengths on the front pack would be the same length as the back pack but I ran out of 1AWG x 1/4" lugs on the bottom packs and I had to reuse leads from the last build... It will be corrected when I add more packs. Bus bar will have better protection as well. )

The 50,000AIC rating of those Carling breakers is at 125VDC. I wouldn't be surprised if it can break even higher currents at typical 16S LFP voltages.

I did the same thing with the breakers and busbars you did.

Haven’t posted mine because I figured people would have a heart attack from it.
 
So would you say Blue Sea 125 amp fuse with rated Blue Sea base per battery I would be good?

Not 100% sure on the correct fuse type between battery and busbar (maybe others can chime in) but possibly a 250-300A T-class fuse between busbar and inverter.

I'm guessing your breakers failed due to the heat generated by the constant high current of the aircon.
