position.
Poor contact between the inverter’s
battery wires and the battery terminals.
Clean battery terminals or inverter wire
contacts. Tighten battery terminal screws.
Blown inverter fuse
The inverter has to be returned for service.
Very poor battery condition
Replace battery
PROBLEM :
‘Battery voltage too low or too high’ error keeps on appearing
Possible cause :
Remedy :
Poor battery condition
Replace battery or charge it first
Poor connection or inadequate wiring
between battery and inverter, resulting in
too much voltage drop
When extending the battery wires of the
inverter make sure you use the correct wire
gauge (
1.5 times larger than the fixed
battery wires). It’s not advisable to extend
the battery wires to more than 3 meters.
General failure in your electrical system (in
case of no direct battery connection)
Check your electrical system or consult an
electrical engineer to check it for you
PROBLEM :
‘Overloaded or shorted output’ error keeps on appearing
Possible cause :
Remedy :
Inverter is overloaded
Make sure that the total power rating of
the connected equipment is lower than the
nominal inverter power rating.
Connected equipment features a bad
power factor (cos
at sinusoidal currents)
reduce the required power consumption of
the load. Please note that for example most
computer loads feature a bad power factor,
which causes a reduction of the maximum
output power of the inverter by approx.
20%.
Connected equipment causes a short circuit
at the inverter’s output
Make sure that the connected equipment is
not broken or malfunctioning. Check if the
AC power cord between the inverter and
the connected equipment is ok. Any
physical damage on the power cord can
produce a short circuit.
Be careful in these
kind of situations!
Connected equipment produces a too large
inrush current
Try to power-up connected equipment
successively, and not simultaneously. Or
connect the load first and then turn-on the
inverter. Otherwise stop using the
connected load, it’s not suitable to drive it
