Troubleshooting
The green
inverter LED
is on.
The inverter has been switched on and
is operational.
n/a
The green
inverter LED
is blinking.
The yellow
ECO LED is
on.
The inverter has been switched to ECO
mode and is in "search" state. In other
words, the inverter load is lower than the
"Wake up power" setting. the inverter
sends a search pulse at regular intervals
to check if a load has been connected or
has been turned on.
If the inverter keeps switching on and
off while there is a load connected, the
load may be too small compared to
the actual ECO mode settings. Either
increase the load or change the "wake
up power" setting.
The green
inverter LED
is on.
The yellow
ECO LED is
on.
The inverter has been switched to ECO
mode and is in "inverting" state. In other
words, the inverter load is higher than
the "Shut down power" setting and is
powering the load.
n/a
The green
inverter LED
is blinking.
The red Alarm
LED is
blinking.
The inverter is off and a firmware update
is in progress or a firmware update has
failed.
If the firmware update failed, retry the
firmware update.
The green
inverter LED
is on.
The red Alarm
LED is on.
Overload warning.
The inverter is indicating that the AC
load is larger than the inverter rating
and that if this situation continues, the
inverter will switch off due to an overload
alarm
Reduce the AC load
The green
inverter LED
is blinking with
a fast double
pulse.
The red Alarm
LED is on.
Overload alarm.
The inverter has shut down due to
prolonged overload and will no longer
automatically restart.
Remove the cause of the overload and
then restart the inverter by switching it
off and then back on again.
The green
inverter LED
is on.
The red Alarm
LED is slowly
blinking.
Low battery voltage warning.
The battery voltage has dropped below
the "Low battery alarm" voltage. Should
the battery voltage drop any further, the
inverter will switch off on a "Low battery
voltage alarm".
Charge the battery and/or turn AC
loads off. Also check if all battery cable
connections have been tightened. Do
the battery cables have a sufficient
thickness, is the battery full and is the
battery still in good working order?
The green
Inverter LED
is on.
The red Alarm
LED is fast
blinking.
High Battery voltage warning.
The battery voltage is too high. Should
the battery voltage increase any further,
the inverter will switch off on a "High
battery voltage alarm".
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.
