Proline 5000™ Inverter by Wagan Tech®5www.wagan.comON/OFF SwitchThis switch turns the inverter ON and OFF.Over Temp LEDThis indicator turns RED as the inverter shuts down because of excessive temperature.Immediately turn off appliances if this occurs. Allow the inverter to cool before continuing.Internal high-speed cooling fans automatically turn on when the inverter is switched on toprovide instant cooling. The inverter may overheat when it is being used in a location that doesnot allow for adequate ventilation.Overload LEDThis indicator turns RED as the inverter shuts down from an overload condition. Immediatelyturn off some appliances to reduce the load. If the continuous combined power requirementof appliances exceeds the inverters continuous rating, the inverter will overload. Sometime anappliance with very high start-up load will cause an inverter to shut down. If battery conditionand cables do not support the load, then more batteries and heavier cables may be required.Bar Graph DisplaysThe inverter is equipped with two bar graph displays to monitor DC input to the inverter. Theseare used to help diagnose problems if they occur.Volts Display:The volts display is the measurement of the voltage at the DC terminals of the inverter, not actualbattery voltage. During high wattage applications the display may show a lower voltage levelthan the battery because of a voltage drop that can occur between the DC input cables andthe battery. This voltage drop should not be greater than 0.25 to 0.5 volts, as a greater voltagewill seriously reduce run time. This inverter will operate with the following input voltage range,varying by model:#3744 — 10-15V DC Input#3744-4 — 20-30V DC Input#3744-8 — 40-60V DC InputThe inverter is equipped with an alarm and shut down feature based on these changes in inputvoltage:Feature: #3744 (12V) #3744-4 (24V) #3744-8 (48V)Alarm sounds when input voltagedrops below:10.5V ± 0.5V DC 21.0V ± 1.0V DC 42.0V ± 2.0V DCInverter shuts down when inputvoltage drops below:10.0V ± 0.5V DC 20.0V ± 1.0V DC 40.0V ± 2.0V DCInverter shuts down when inputvoltage rises above:>15.0V DC >30.0V DC >60.0V DCDuring charging from a generator, solar panel or AC powered charger the battery voltagewill be higher than when it is resting. Voltages greater than allowed may cause damage to theinverter. Damage caused by excessive voltage input is not covered under the warranty.
