DER storage meter wiring with solark

[Subestile]

I am changing my battery storage from the tesla powerwall 2 that came with my system and adding to the ruixu battery storage I installed with the solark assuming I can figure this out. SRP has a DER storage meter which per the DER rep at SRP only sees if the system is charging or discharging the battery. I can not find anything in the solark manual on how to get this signal to the meter. it obviously knows this info as it displays on the main display but im at a loss of how to submit the new DER application as I have to specify the wiring information to SRP to get this process underway. I have emailed solark customer support also but have not heard anything back yet.

edit: per solark tech support they do not support this type of monitoring directly. open to suggestions if its even possible to be able to wire this so it will provide the data they are requiring on the der storage meter.

still trying to find a solution for this, I am going to be removing the powerwall/gateway2 in the next few weeks to get it to the new owner. would like to avoid having to have SRP come out and remove the meter as involving them generally has lead to more headaches than not in the past. Thanks for any info that can be available. my enphase system thats tied to the powerwall will be re-routed the same way it currently is as ac coupled into the solark and will be adding (hopefully) another 30kwh of Ruixu batteries to replace the powerwall2 once i get a little more saved.

You could use a voltage sensor. Roughly, if the battery voltage is above 53.5v it is charging. Might be lower if the battery was drained.

There might be a DC version of a CT.
