"server rack fusing”

[threepets]

Is fusing my battery box in this fashion incorrect?

I think that looks good, hope positive cable has no chance to get insulation cut through and short to chassis.
Does negative cable come off bottom right?

I see wire looms are being used as insulators around busbars. Bolts stick out. There is a cover, correct? Is it able to fit, probably cut in sections?

I used rubber grommets where 4/0 cable passed through the battery case, negative comes through bottom right.

SShould there be more attention shown to the Buss Bars for safety? I don't understand "wire looms are being used as insulators around busbars".

My way, two racks stacked 6-EG4 LP4 and 6-EG4LL V1.

Blue sea holder direct to the busbar.

Nice job on your build. How many amp fuse?

I have observed that after exposed busbars were used, these rack vendors have added plastic which is normally used to organize runs of LAN cable. They weren't designed as insulators, nor tested by UL with a mechanical finger and applied pressure to see if hazardous voltages or currents can be connected.

The busbar is about 55V, but more important can deliver massive current if shorted. Supposedly BMS turns off for over-current, but I don't trust transistors for safety. It looked like the bolts are somewhat exposed, could be contacted with a tool or jewery.

Was a cap provided for the plastic wire looms? That would help prevent contact. Maybe the term is "channel" not "loom"

6' Vertical Cable Channel

The 34-207616-BK is a six foot tall bulk vertical cable channel with flexible finger ducts. This beast holds up to 180 cables and makes you look good in front of your boss.

I want to add an AC Battery charger 48v ,any suggestions?

yes there was a cap supplied ,it will not fit over the bolts. Buss bar needs to be recessed more.

there has to be a better way of dealing with the exposed buss bars

Solar charge controller? There are many. Often one from manufacturer of your inverter is good, but people do mix and match.

Or do you mean AC powered charger?

I've got a couple charge controllers, Outback and Midnight. But most of my equipment is SMA, including an inverter/charger.

If cabinet door requires a tool, that helps keep the uninitiated away. But covers are good when you're working on it.

If busbar can be set lower to fit provided cover, that would be good.
I used recycled heater hose hose to cover battery terminals. Then discovered they are conductive (but still good for preventing massive shorts.) You could get rubber hose and split it.

Thanks for pointing this issue out. I took the side cutters and made the covers work

Just ordered the Chargeverter from Signature Solar, not expected until March , maybe.

The container ships have to take the long way around and that's reducing capacity, so could definitely be later than sooner.
