SD-Imax The inverter has detected an overcurrent on the AC side.
The inverter disconnects from the power distribution grid. As soon as the
error has been remedied, the inverter tries to feed into the power
distribution grid again. If the inverter cannot feed into the power
distribution grid after several attempts, the inverter trips the permanent
operation inhibition.
Corrective measures:
• Contact installer.
SD-INV-Bridge The inverter has detected a fault in the power electronics.
The inverter disconnects from the power distribution grid. As soon as the
error has been remedied, the inverter tries to feed into the power
distribution grid again. If the inverter cannot feed into the power
distribution grid after several attempts, the inverter trips the permanent
operation inhibition.
Corrective measures:
• Contact installer.
Shut-Down Overcurrent present at the DC input of the inverter.
The inverter switches off.
Corrective measures:
• Contact installer.
STM-Timeout The inverter has detected an internal program run disturbance.
The inverter disconnects from the power distribution grid. As soon as the
error has been remedied, the inverter tries to feed into the power
distribution grid again. If the inverter cannot feed into the power
distribution grid after several attempts, the inverter trips the permanent
operation inhibition.
Corrective measures:
• Contact installer.
Vac-Bfr
Vac-Srr The AC line voltage has exceeded the permissible range.
The cause may be disconnection of the power distribution grid or an AC
cable. The inverter disconnects itself from the power distribution grid to
prevent islanding.
Corrective measures:
• Contact installer.
