5.8 OVERLOAD
The fault LED will come on when the Inverter has shut itself down because its output circuit has
been short-circuited or drastically overloaded. Switch the ON/OFF switch to OFF, correct the fault
condition, and then switch the ON/OFF switch back to ON.
Some induction motors used in refrigerators, freezers, pumps and other motor operated
equipment requires very high surge currents to start. The Inverter may not be able to start some
of these motors, even though their rated current draw is within the Inverter.
If the motor refuses to start, observe the battery voltage indicator while trying to start the motor.
If the battery voltage indicator drops below 11 volts while the inverter is attempting to start
the motor, this may be why the motor will not start. Make sure that the battery connections
are good and that the battery is fully charged. If the connections are good and the battery is
charged, but the voltage still drops below 11 volts, you may need to use a larger battery.
5.6 INPUT VOLTAGE
The Inverter will operate from input voltage ranging 10.5 - 16V. If the voltage drops below
10.5 V, an audible low battery warning will sound and the voltage indicator will be in the lower
red zone. The Inverter will shut down if the input voltage drops below 10 V. This protects your
battery from being over discharged.
The Inverter will also shut down if the input voltage exceeds 16V. This protects the Inverter
against excessive input voltage. The voltage indicator will be in the upper red zone. Although
the power inverter incorporates protection against overvoltage, it may still be damaged if the
input voltage is allowed to exceed 20V.
5.7 OVERTEMP
The fault LED will come on when the Inverter has shut itself down because the Inverter has
become overheated. The Inverter may overheat because it has been operated at power levels
above its rating, or because it has been installed in a location that does not allow it to dissipate
heat properly. The power inverter will restart automatically once it has cooled off.
