Charging EG4 Power Pro batteries in parallel with EG4 Chargeverter in a emergency

I have a master bus bar in the trough under the two Sol-Arks and everything connect to the bus bar. Battery banks, two groups, the 3 Power Pro's, and the rack of 6 LLV2's. They are all in closed loop. The Chargeverter will soon be connected to the main bus bar as well. Currently its connected to the charging bus barr in the conduit box over the central PP battery. I'm re-tooling my system to be able to switch between Sol-Arks and the EG4 18Kpv on the left wall that will be part of a comparison study.

I am thinking of doing the same thing as the OP, but I am considering connecting to the PP batteries on the ends. I believe this will provide a better equalization of charge. Is this true? Will it matter? Obviously it is easier to connect just to the battery at the end.

I have six EG4 LifePower4 batteries installed in an EG4 six battery rack.
The positive of my EG4 ChargeInverter is connected directly to the positive bus bar in the rack. The EG4 ChargeInverter negative is connected to the inverter side of a Victron shunt. I have had no issues using the ChargeInverter charging the batteries from the grid. I can also plug the charginverter into my 10kw generator and it provides power to the inverter (as if it were a battery) and any power not needed by the inverter flows into the batteries.

Not really.
Putting power in wherever, is beneficial.

I had seen a Will Prouse video and he commented on the buss bar configuration on a rack system. I believe he modified it, so that the connect went through the end batteries, to force better equalization. I know that differences in cable length represent a difference in resistance, and therefore the rate of charge, but I also understand that this could be miniscule and insignificant.
 
The bus bars in the PP are rated for 600A, the standard 2/0 interconnect cables are good for 200A, the chargeverter will only do 100A, pretty sure it’s not going to be a problem.

Connecting to opposite ends of the three batteries isn’t a bad idea, unless you end up having to make extra cables.

Connect it however you want. It doesn't really matter, with a backup charger.
 
I have two EG4 PowerPros on my 18K and a chargeverter, no bus bars, and no interest in adding them. I was thinking I'd cut the ring connection off the chargeverter's wire, strip and re-crimp using a reducer on my spare 4/0 cable to right angle amphenol connector. It looks like the 25mm cables off the CV are really 4 AWG. I think these parts would do the trick, can anyone confirm?

You can connect the chargeverter anywhere to the battery system that you want.
FYI: it's an 18kpv.

yea, I'm AC coupled so I'm calling it an 18K deal with it :) - I read the responses earlier about where to connect to the PowerPros, that wasn't my question.

Those reducers look right (the new Chargeverter GC comes with Amphenol connectors already!), but the crimp tool has the usual 'this is metric and you'll have to use a few sizes to get 4/0 to work' reviews. I always ready the 1-star reviews to try to determine what could go wrong. However, I've got a set of metric crimp tool on the way as well, there don't seem to be AWG versions without spending a fortune...
