The one on the right is a new style of buss bar. How does it connect to the cabinet?

The box is super heavy duty! It's an off brand I found on offerup. Not to happy with the bus bar so got to find a thick copper bar to make one.

I like the idea of that bus bar. Why are you not happy with it?

It feels thin... I got to find my calipers measure the thickness.

Does it get hot under full load? That is the main concern I would have.

@wildbird12 not sure as I just set it up last night... Im only charging the batteries today no loads.

New user here but I just wanted to mention i had 4 eco worthy delivered to central oregon from ca today aswell. All packed very well and not a scratch on them so I guess I cannot join the bent ear club! Handles were packed separately under each unit in a foam cutout and attach with 4 screws. As mentioned the fronts are packed very well with a dense black foam not typical styrofoam...the fronts have nice enough packing that i think ill save a few of the pieces for other projects! My 4 ranged from 26 to 29 percent charge. I paralleled and after about 6 hrs charge at 45 amps I'm at 75 percent and went to bed...or uh, reading up on new posts! I'm off grid and don't live here full time but I plan on keeping the system going for a fridgerator and about 200 watts of other intermittent loads.
I read above about mention of a sleep setting after 4 days...how do I disable or avoid a shutdown? I'll charge to 100% in the morning and get a good deep cycle tomorrow. So far I love these things! No more hydrometer and jugs of distilled water...and no more wire brushing corroded terminals!!!! Haha.

Welcome to the EWR, Eco Worthy Rack Club
Since you have multiple units it may not go to sleep. I believe others said they had the master and a few slaves plugged in and the data activity kept them from going to sleep. As long as they see current or data they will stay running. I'll have to go back into pictures and find the setting. Just woke up with a cup of Java.

VERY impressive, Bill...thank you for this! 
Where did you buy the server rack from? I assume those are not ecoworthy or EG4 rack.Sorry if they don't come up first time posting pics from the cell.

I got it to work. Way to go with Eco-Worthy, JBD, and Solar Assistant all working together to make this happen!

May do the same when I hook up SA.
But looks like they have communication working with EW to Sa now too.
Only thing left is for SA to incorporate EG4 communication at the same time as other protocols.

The rack is an off-brand, but it’s actually really robust and heavy-duty. I bought it locally on the OfferUp app.
I do have the EG4 rack with 4 EG4-LLs and 2 Eco-Worthys (on the left). The other rack (on the right) is all Eco-Worthy batteries.
If I’m not mistaken, the off-brand rack is WirenTech.

I really like the eco-worthy design I just wish I had a couple more slots so I can buy some more batteries

Oof, that’s a tough one… The group I bought it from resells random items they get at a discount, so I’m sure shipping wouldn’t be economical.Where do we buy it the price how much is shipping we need more input
I think the better bet is to reach out to @Bill Young and get his take on possibly bringing this to market.
@Bill Young thank you for the great work on this. I saw that on the eco worthy site, that the 48v batteries will be getting UL listing this month. Can I order them now and you ship them after they are approved?

I bought 2 more server racks off Facebook Marketplace this weekend (couldn't resist). Wife asked "You're not getting more batteries, are you?" I told her that I just wanted to prepared, in case an opportunity presented itself!I really like the eco-worthy design I just wish I had a couple more slots so I can buy some more batteries

However, I prefer a server rack that has two bus bars capable of supporting what current six batteries can deliver.
Consider this; Each of the two negative (and two positive) terminals are actually single terminals mounted side by each and connected internally by a short bus bar (approximately 2 3/4 inch long by 3/4 inch wide by 1/8 inch thick).
The batteries are connected daisy chained by their positive and negative terminals such that they are (equivalently) in parallel.
Assume total current flow (inverter load) is 100 amps with six batteries.
Since current flows from negative to positive;
The cable from the battery furthest from the negative connection to the load (inverter) "top battery" to the next (second battery) will carry 16.66 amps. The cable for the second battery in the stack connecting it to the third will carry the current from the first as well as the current from the second (33.33 amps) and so on until the final terminal to the "load" (inverter) carries the entire 100 amps.
Each of the internal bus bars will also carry all the current from the batteries "above/before" it.
What are these short bus bars rated for?
