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 11.3V +/- 0.3V, an audible low battery warning will sound. The inverter will shut down if the input voltage drops below 10.3V +/- 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 15.5V+/-0.5V. 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. 18 Operation Troubleshooting Guide TIntrrooubleOspehratoionotingACsuGssitsotumaneicrde e Warranty • Problem/Symptom Possible Causes Solution Low output voltage Overload Reduce the load.
