Q at Night 86 SCCPXT BA E7 en 5 5 User Manual SMA Solar Technology AG 10 Function Description If the AC power generated by the inverter falls below 5 kW the inverter switches from feed in operation to Q at Night operation The inverter feeds in reactive power in accordance with the parameters set Since this status can also occur during the day the DC switchgear initially remains closed in order to avoid unnecessary switching cycles of the DC switchgear If the inverter is in Q at Night operation for one hour or the DC current falls below 60 A the DC switchgear opens The inverter continues to feed in reactive power If reactive power feed in is interrupted after a grid fault and the AC disconnection unit is opened while the DC switchgear is open the DC circuit is initially pre charged This reduces the stress on the electronic components This process takes a maximum of one minute Once the DC circuit is sufficiently pre charged the AC disconnection unit is closed and the inverter monitors the grid limits If all of the feed in requirements are met the inverter will revert to reactive power feed in within one minute While the inverter is feeding in reactive power the inverter monitors whether the conditions for active power feed in are met Once the feed in requirements are met the inverter closes the DC switchgear and switches to feed in operation To protect the PV array the amount of reverse current is set by default to 60 A in
