My experience and advice from Tech Support at Fortress was NOT to network the eVault 18.5 with only 2 batteries. We just installed two eVault18.5 with one Sol-Ark12K. The communication doesn't work properly with only two batteries. The tech advised to run both batteries independently as Masters, which was the only way we could make it work. All attempts at networking them failed. We didn't try to network the batteries to the inverter. Of course, Murphy's Law dictated that this was a remote system with no internet or cell reception. So, I had to make a second trip out to make it work after I found this out from Tech Support the next morning. Apparently you can network one battery with the Sol-Ark in closed loop but the tech I talked to said how this is done (special com cable) varies with the version of the Sol-Ark one is using since Sol-Ark has been making changes to their circuit board.
