Fault signals
When these error messages are displayed, the grid feed is interrupted, the red LED (3) lights up and the fault signal relay is switched. This
error correction takes a country-specifi c length of time. Afterwards, the red fault LED (3) goes out, the fault signal relay drops out again,
and the display signals that it is ready to feed into the grid once again. If the fault is no longer present, the Powador inverter begins
feeding into the grid once again after a country-specifi c time period. Many of these fault signals point to a fault in the grid, and are,
therefore, not an operational fault on the part of the Powador inverter. The minimum triggering levels are determined by applicable
standards (e.g. VDE0126-1-1), and the inverter must switch off if the permitted values are exceeded.

Comment
Only for a brief period after being fi rst switched on in the morning.
Grid parameters and generator voltage are being checked.
Insuffi cient generator voltage and generator power. The status before it
switches over to night shutdown mode.
The inverter continues to operate with minimum MPP voltage when the
grid feed power is low.
The inverter is feeding into the grid.
The line relay and the shutdown of the power electronics are tested
prior to the commencement of grid feed mode.
For internal operation only.
If the generator is producing too much power, the inverter limits itself to
the maximum power. This can occur in the midday hours if the genera-
tor has been too largely dimensioned. This is not a malfunction.
The inverter can only begin feeding into the grid once the PV voltage
falls below a specifi ed value.
The inverter was switched to standalone mode by the Powador Grid-
Save. The inverter is disconnected from the public low-voltage grid.
Frequency-dependent power reduction is activated with the activa-
tion of the BDEW Medium Voltage Directive. Power reduction starts at
50.2 Hz.
The AC current is limited once the specifi ed maximum value has been
reached.
