5.2.2 Device > Operation > PowerBalancer > PowerGuardGrid fault reported (PowerBalancer)

Max. load unbalance for PowerBalancer (PowerBalMax)

Description Value DescriptionOperating mode of the SMA Power Balancer to prevent unbalanced loads in three-phase systems.

Off The SMA Power Balancer is deactivated. In case there is a device or line voltage fault with an inverter, only the affected inverter is disconnected from the power distribution grid and the other two inverters continue operating with unrestricted power.

PhaseGuard Operating mode in which a distinction is made between a device and a line voltage fault. In the event of a device fault at the first inverter, the other two inverters continue to operate without reducing their power. In case of a line voltage fault, all inverters immediately disconnect from the power distribution grid.

PowerGuard Operating mode in which no distinction is made between a device and a line voltage fault. The inverter with a disturbance disconnects from the power distribution grid and the two other inverters restrict their power depending on the set country standard or to the power level set under PowerBalMax.

FaultGuard Operating mode in which a distinction is made between a device and a line voltage fault. In case of a device fault, the error message is output on the other two inverters with a time delay of 5 minutes. After 5 minutes elapses, the other two inverters disconnect from the power distribution grid. In case of a line voltage fault, all inverters immediately disconnect from the power distribution grid.

Coefficient of power calculation based on Udc (Wind_a1)

Coefficient of power calculation based on Udc^2 (Wind_a2)

DescriptionPower controller settings ki componentThis operating parameter defines the control speed of the wind turbine power curve. The inverter reacts to changes in the DC input voltage by adjusting its output power using the wind turbine power curve. The higher this parameter is set, the larger the power jump in response to the changes in the DC input voltage. Values that are too high lead to vacillations and instability in the system. Values that are too low delay the optimal load of the turbine and thereby reduce the yield.

5.2.6 DC Side > DC SettingsInput start delay (T-Start)

Maximum voltage input (Vpv-Max)



DescriptionThis parameter defines the starting point of the wind turbine power curve.When the DC input voltage reaches this value after grid synchronization, the inverter uses the wind turbine power curve to start the load of the small wind turbine system and feeds power into the power distribution grid.

DescriptionParameter for the controlled startup of the small wind turbine system. Only once the inverter is connected to the power distribution grid will the small wind turbine system not be charged rapidly, but rather with a configurable ramp. After the connection process, this parameter will no longer be active.A percentage value of the inverter's nominal power is set, which limits the maximum amount by which the output power is increased per minute when connecting.

DescriptionTime during which the inverter monitors the grid and the PV voltage before it connects to the power distribution grid.

DescriptionMaximum DC voltage that may be present on the inverter to prevent the inverter from being damaged and to allow for safe grid feed-in.

DescriptionThe DC voltage required before the inverter begins feeding power into the grid. This value corresponds to at least the minimum MPP voltage which is required in order to always guarantee safe connection to the grid, and to minimize grid relay wear.

DescriptionTarget PV voltage for constant operational voltage.

DescriptionThe CO2 factor indicates in g/kWh how much CO2 is produced for every single kilowatt hour of electricity generated in the country. Depending on the technology used and the efficiency, the CO2 factor can vary between the different electric utility companies in the region. You can find out the value of the CO2 factor of the electricity supplied in your region from your electric utility company.

Cause and corrective measuresThe internal test of the inverter control system firmware failed. Corrective measures:

• If the message occurs frequently, contact the SMA Service Line.

Cause and corrective measuresThe inverter reduces its output power due to excess temperature.Corrective measures:

• Clean the fans.



Ground fuse missing (GFDI Fuse Open)

Interference of device (Shut-Down)

Internal communication (Bfr-Srr)

Internal meas. comp. fault (MSD-Idif, MSD-FAC)

Cause and corrective measuresThe ground fuse has opened. Corrective measures:

• Check the PV plant for a ground fault.• Replace the ground fuse.

Cause and corrective measuresOvercurrent present at the DC input of the inverter.The inverter switches off.Corrective measures:

• If the message occurs frequently, ensure that the design and circuitry of the PV array are correct.

Cause and corrective measuresCommunication between micro-controllers is interrupted. Corrective measures:


Cause and corrective measuresAn internal measurement comparison fault has been detected.The measured values of both processes (OCU and current controlling unit) deviate too much from one another. Corrective measures:

Cause and corrective measuresThe power frequency is outside the permissible range. The inverter has disconnected from the power distribution grid.Corrective measures:

• Ensure that the AC cable is correctly connected.• Ensure that the power frequency is within the permissible range.

If the power frequency is within the permissible range and this message continues to be displayed:• Contact the SMA Service Line.
