The under voltage indicator indicates that the power inverter has shut itself down
because its input voltage has been lower than the low limit.
5-6. Over Temp Indicators:
The over temp indicator indicates that the power inverter has shut itself down because
it has become overheated. The power inverter may overheat because it has been
operated at power levels above its rating, or because it has been installed in a loction
which does not allow it to dissipate heat properly. The power inverter will restart
automatically once it has cooled off. “Over Temp” indicator may also indicate a fan
failure.
5-7. Overload Indicator:
The overload indicator indicates that the power inverter has shut itself down because
its output circuit has been short circuited or drastically overloaded. Switch the front
panel ON/OFF switch to OFF, correct the fault condition, and then switch the
ON/OFF switch back to ON.
6. Operating Limits:
6-1. Power Output:
The 1500W inverter will operate most AC loads within its power rating. When
determining whether a microwave oven can be operated by the 1500W inverter,
remember that the power commonly advertised for microwave ovens is the cooking
power (the power delivered to the food); not the power actually consumed by the
microwave oven. The microwave oven will consume 40% to 100% more than its
advertised cooking power. Check the rating sticker on the back of the oven to
determine its actual power draw. The 1500W inverter will operate small microwave
ovens (0.2 to 0.3 cubic foot capacity) that draw about 1700 watts. It will provide 3
minutes of cooking time.
Some induction motors used in refrigerators, freezers, pumps and other motor-
operated equipment require very high surge currents to start, often as much as 6 –7
times rated. The power inverter may not be able to start some of these motors, even
though their rated current draw is within the power 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 the low input level while the
inverter is attempting to start the motor, this may be the reason the motor won’t start.
Make sure that the battery connections are good and that the battery is fully charged.
