Troubleshooting Guide
Problem/Symptom Possible Causes Solution
Low output voltage Overload Reduce the load.
No output voltage Low input voltage Recharge battery.
Check connections
and cable.
No output voltage Thermal Allow inverter
after prolonged use shutdown to cool off.
Reduce load,
continuous
operation input
current required.
Improve ventilation;
Make sure ventilation
openings in the
inverter are not
obstructed.
Reduce ambient
temperature.
No output voltage, High input Make sure
"Protect" indicator voltage the inverter is
connected to
lighted
12V battery.
Check regulation
of charging system.
No output voltage Short circuit Check load for
proper operation.
No output voltage Inverter Turn inverter on.
switched off
No power Check wiring
to inverter to inverter.
Reverse Observe
DC polarity correct polarity.
Low battery alarm Poor DC wiring Check
on all the time connections.
Poor battery Make sure battery
condition is fully charged.

Notes
All protection is automatically recovered.
To protect the battery, if the unit needs to be restarted
after low voltage protection, the voltage of DC input
should be above 12V.
To extend the life of the fan, it will stop when there is no
load. The speed of the fan increases as the load increases.
The unit is completely insulated in input and output for
added safety.
