Solution
Reduce the load.
Recharge battery.
Check connections
and cable.
Allow inverter
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.
Make sure
the inverter is
connected to
12V battery.
Check regulation
of charging system.
Check load for
proper operation.
Turn inverter On.
Check wiring
to inverter.
Observe
correct polarity.
Check
connections.
Make sure battery
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.
