Supported inverters
Currently, system can support AC Coupled inverters (single phase) only on Firmware. D0.291-A0.282
Plant operation
Plant EMS can support 3 AC Couple inverters and 6 EM115 meters in total. In discharge time, EMS can control all inverters discharge to the load when all batteries SOC difference within 1%. When the soc difference between the two batteries is greater than 1%, EMS will control the high SOC battery discharge to balance the grid, if the load power greater than the inverter maximum active power, the high SOC battery will full power discharge and the lower SOC battery will balance the rest of load. In charge time, EMS will control all inverters full power charge to batteries.
