Hi, I have 3 phase system Quattro-II with emus BMS, 3 x MPPT and PV AC inverter. Many of my systems with emus BMS works good but I have problem with one of them.
After fully charged, emus BMS disable charging and then batteries drain to grid with full current 280A. The same is when the BMS is charging and I manually disable the charging in the BMS. Batteries are immediately discharged into the grid without control. DVCC is enabled. It is only works good when I turn off DC-coupled PV feed in excess. Then after stop charging its ok.
In other systems with emus I don't have such a problem.
Regards
