Operating Instructions Powador 3200 / 4400 / 5300 / 5500 / 6600_EN
Status

Inverter has just switched on
Only for a brief period after being fi rst switched on in the morning.
1
Waiting to start
Grid parameters and generator voltage are being checked.
2
Waiting to switch off
Insuffi cient generator voltage and generator power. The status before it
switches over to night shutdown mode.
3
Constant volt. control
The inverter continues to operate with minimum MPP voltage when the
feed-in power is low.
4
Feed-in mode
The inverter is feeding into the grid.
8
Self test
The line relay and the shutdown of the power electronics are tested
prior to the commencement of feed-in mode.
9
Test mode
For internal operation only.
11
Power limitation
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.
60
PV voltage too high
for feed-in
The inverter can only begin feeding into the grid once the PV voltage
falls below a specifi ed value.
61
Power Control
Power Control was activated by the grid operator. The inverter limits its
power.
62
Standalone mode
The inverter was switched to standalone mode by the Powador Grid-
Save. The inverter is disconnected from the public low-voltage grid.
63
P(f) frequency-dependent power
reduction
Frequency-dependent power reduction is activated with the activation
of the BDEW Medium Voltage Directive (“Mittelspannungsrichtlinie”).
Power reduction starts at 50.2 Hz.
64
Output current limiting
The AC current is limited once the specifi ed maximum value has been
reached.

Fault messages
When these error messages are displayed, the feed-in 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. Once the fault is gone, the Powador inverter feeds into the
grid 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 opera-
tional 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.
When the
Relay 33
function is activated, LED (3) is not used to indicate faults. If the contact is connected in ”Relay 33” mode, LED (3)
illuminates to indicate this status. The LED remains lit as long as the contact is connected.
If the inverter then experiences an error, it is not indicated by the LED (3). Instead, it only appears as an error message on the display.
