LED indicators
The inverter is equipped with three LEDs that provide informa-
tion about the various operating states as follows:
Figure 4.2:
LED indicators
LED (1) (green):
The LED begins to light up as soon as the minimum voltage of
a photovoltaic module has been reached and goes out again
when the module voltage has fallen below this value.
The LED signals that the inverter is in standby mode. The inverter
is ready for operation.
LED (2) (green):
The LED always lights up when the inverter is feeding into the
grid.
LED (3) (red):
The LED displays when feed-in has been interrupted due to a
fault or when the potential-free contact is connected in ”Relay
33” mode.
Wait approximately 10 minutes to see if the fault is only tem-
porary in nature. If this is not the case, notify your authorised
electrician.
Check whether the fault in question relates to a general power
failure or whether the fuse between the counter and the
inverter has blown. If the fuse has blown, notify your autho-
rised technician. If there was a power failure, simply wait until
the fault has been cleared. The system automatically restarts.

Keys ”1” and ”2”

Powador control buttons
Key “1” is used to switch between the various displays for
measured values and data. Key “2” can be used to confi gure
settings. Here, menu navigation is divided into two levels. In
level 1 (display mode), measured values such as the PV array
voltage can be read. Here, only key “1” is activated. In level 2
(confi guration mode), key “1” is also used to navigate through
the individual displays. Settings, such as interface selection,
are confi gured with key “2”.

IMPORTANT
If the feed-in phase fails (power failure on the public
grid), LED (3) does not light up. If this happens, all LEDs
and the display go out. The inverter is shut down com-
pletely.
The inverter can only resume its normal operation when
the feed-in phase is available once again.
ACTION
By pressing key “1” you can choose which measured
value is to be displayed.
The menus are continuous, which means that when you
arrive at the last entry in a menu, the fi rst entry is dis-
played once again the next time key “1” is pressed (see
fi gure 4.4).
IMPORTANT
The potential-free contact can also be used in ”Relay 33”
mode (section 4.4). In this case, 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
(3) remains lit as long as the contact is connected.
If the inverter then experiences an error, it is not indi-
cated by the LED (3). Instead, it only appears as an error
message on the display.
