Green Light

Power on – The green light should remain on steady.

Red Light and/or Alarm

Current overload – The red light will turn on momentarily, then the inverter will shutdown. The inverter will continue to check for appropriate current levels while trying to restart the load.

DC input voltage overload – The red light will turn on and the inverter will shutdown. The inverter will continue to check for appropriate voltage levels while trying to restart the load.

DC input voltage shortage – As a warning that the voltage is getting low, the internal alarm will sound. When the voltage is too low, the inverter will shutdown and the red light will turn on. The inverter will continue to check for appropriate voltage levels while trying to restart the load.

Temperature overload – The red light will blink, then the inverter will shutdown. The inverter will continue to check for appropriate temperature levels while trying to restart the load.

NOTE A momentary sound of the internal alarm and/or flash of the red light is normal at start up.

The inverter can deliver 800 watts for about 60 minutes. The inverter must cool for 15 minutes before it can resume operation at 800 watts. Note: The wattage rating applies to resistive loads.

The inverter will operate most AC loads within its power rating. Some induction motors used in freezers, pumps, and other motor-operated equipment require 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’s limits. The inverter will normally start single phase induction motors rated at one-half HP or less.

Input Voltage

The inverter will operate from input voltage ranging from 10 volts to 15 volts. Optimum performance will occur when the voltage is between 12 volts and 14 volts. If the voltage drops below 10.5V+/-0.3V, an audible low battery warning will sound. The inverter will shut down if the input voltage drops below 9.5V+/-0.3V. This protects the battery from being over-discharged. It will restart when the input voltage exceeds 12V+/-0.3V.

The inverter will also shut down if the input voltage exceeds 15.75V+/-0.75V. This protects the inverter against excessive input voltage. Although the inverter has protection against over-voltage, it may still be damaged if the input voltage were to exceed 16 volts.
