I have 2 x 12kv Sunsynk inverters installed with 2 x 530 Ah batteries. I have been having an issue where whenever the schedule allows the state of charge to step down, the system appears to be creating phantom load which results in the batteries rapidly discharging to the next set SOC. The images provide two example days.  Tests have confirmed that there is no significant load in the house. 

Does anyone know what could be causing this issue. 

I had this. Was CT Coil issue...facing the wrong way. For my sytem to work properly, I actually have 2 coils facing one direction and the other the opposite. The ends in the inverter all installed properly and alternating white/black cable. I can only assume that the one coil itself is wired incorrectly.
