7. TROUBLE SHOOTING
Problem (Possible) Cause Solution
A buzzer sounds
The input voltage is becoming
too low.
Charge the battery.
Red indicator ‘fault’ lights
Problem at the input side.
Battery voltage too low or too
high. The 230VAC output is
shut down.
Check the input voltage. Make
sure that this value falls
between specifications of the
inverter. The inverter will re-
start automatically when the
input voltage is between the
limits again.
Temperature protection active
- check that the fan is working
and that the inverter has
sufficient ventilation
possibilities
-
inverter is located in a location
with a high ambient
temperature. Place the inverter
in a cooler environment.
- reduce the load.
Red indicator ‘fault’ blinks
slowly
Problem on the output
There is a short-circuit or
overload. Check the consumers
on faults and the height of the
total load. When the problem
has been resolved, the inverter
will restart automatically.
‘Power’ led lights, but the
connected equipment does not
work
Battery capacity too low to
supply the requested power.
Conn
ect a higher capacity battery
(set).
Weak connection between
battery and inverter.
Check all connections and
cables.
The cables used are too thin.
Mount cables matching the
length and capacity.
