The green
Inverter LED
is on.
The red Alarm
LED is
blinking with a
double pulse.
High temperature warning.
The internal temperature is too high. If
the temperature increases any further,
the inverter will switch off on a "High
temperature alarm".
Reduce the AC load and/or move the
inverter to a better ventilated area.
The green
Inverter LED
is on.
The Alarm
LED is
blinking with a
fast single
pulse.
High DC ripple warning.
The DC voltage has a too high ripple
voltage. If the ripple voltage increases
any further, the inverter will switch off on
a "High DC ripple alarm".
Check if all battery cable connections
have been tightened. Do the battery
cables have a sufficient thickness? DC
ripple is related to a voltage drop over
the battery cables. For more information
on DC ripple and how to prevent it, see

The green
inverter LED
is blinking with
a fast double
pulse.
The red Alarm
LED is slowly
blinking.
Low battery voltage alarm.
The inverter has shut down due to low
battery voltage.
To restart the inverter, charge the
battery or switch the inverter off and
then back on again.
Check the battery voltage at the
battery terminals of the inverter. Also
check the DC fuses, cables, and cable
connections

Protections and automatic restarts [14]
chapter.
The green
inverter LED
is blinking with
a fast double
pulse.
The red Alarm
LED is fast
blinking.
High battery voltage alarm.
The inverter has shut down due to high
battery voltage.
Reduce the DC input voltage, check
if the battery voltage is correct and if
the battery bank is wired correctly. Also
check if there perhaps are faulty or
incorrect chargers or equipment with a
faulty charge regulator.
The inverter will automatically turn
back on when the battery voltage has
dropped to an acceptable level.

inverter LED
is blinking with
a fast double
pulse.
The red Alarm
LED is
blinking with a
double pulse.
High temperature alarm.
The inverter has shut down due to high
temperature.
Wait until the inverter has cooled down.
The inverter will automatically turn back
on when its internal temperature has
dropped to an acceptable level.
Check the environment of the inverter,
can the ventilation be improved, or
can the inverter be moved to a cooler
location?
