Problem
Possible cause
Remedy
Only mode indicator LED
’inverter on’ blinks red
once per second.
Battery voltage is too low
(<10V).
Apply mains voltage to the AC input and start
charging the battery.
Problem
Possible cause
Remedy
Only mode indicator LED
’inverter on’ blinks red
twice per second.
Inverter is overloaded.
Make sure that the total power rating of the AC output
load is lower than the nominal inverter power rating.
Connected AC output load causes a short circuit.
Make sure that the AC output load is not defective.
Check if the AC output wiring and connections are
not creating a short circuit.
Connected AC output load
causes a too large inrush current.
Try to power-up connected equipment successively,
and not simultaneously. Otherwise stop using the
connected load, it’s not suitable to power it with this
inverter.
Problem
Possible cause
Remedy
Mode indicator LEDs
’inverter on’ and
’charger on’ are blinking
red three times per
second.
The Inverter Charger Combi has shut down
due to a too high temperature.
Reduce the AC output load in inverter mode.
Try to reduce the ambient temperature around the
Inverter Charger Combi. Make sure that there is a
clearance of at least 10cm around the unit. Do not
obstruct the airflow, place no items on or over the
unit. Keep the Inverter Charger Combi away from
direct sunlight or heat producing equipment.
Problem
Possible cause
Remedy
Mode indicator LED ’AC
in’ blinks red once per
second.
AC input signal is present but not within required
voltage and frequency borders.
Make sure that the AC input voltage falls within
185V – 270V and 45Hz – 65Hz.
Problem
Possible cause
Remedy
All mode indicator LEDs
’inverter on’, ’charger on’
and ’Line’ are blinking
red twice per second
(manual restart needed)
Maximum AC transfer switch current has been
exceeded.
Reduce the AC output load
Problem
Possible cause
Remedy
Output power bar is red
(inverter mode).
The inverter is overloaded and will shut down after a
certain time (depending on the amount of overload)
Reduce the AC output load.
Problem
Possible cause
Remedy
All mode indicator LEDs
’inverter on’, ’charger on’
and ’Line’ are blinking
red four times.
Device or connection fault.
Inverter Charger Combi is defective, return for
service. External AC source is connected to the
AC output instead of the AC input.
