Confirmed that he "believes" the correct port to use on the battery with solark is the canbus port.
He has offered me a partial refund for the battery since I was explicitly clear when I purchased it that I wanted on that communicated closed loop with the solark. He assured me it would...well it has never worked for me. He has since stopped selling this battery for the most part and is selling this in its place....
Battery has built in soft start function - when the inverter needs to start from the battery it can reduce the current impact.

Needless to say my faith in the guy is pretty shaken to the point I am not going to return this battery and then spend extra money for this new version that supposedly also communicates via closed loop with the solark.
All the battery does for me is act as an emergency backup so not sure its the end of the world that it dosent work in closed loop communication but still sucks that I paid close to the same amount of money for this when I could of gotten one that did for nearly the same price.
What steered me away from other batteries is the shipping cost. This guy was localish at the time so no shipping costs made the $1500 battery closer to $1500 not $2000 like the other options out at the time..
He is no longer really local as I have asked several times for him to show me what I am doing wrong and he is always too busy setting up new systems down in Georgia now...
