Low Voltage Inverter Problem. Here is a video i created for you that explains why a squarewave inverter s output voltage can measure low ac output volts. Diagnosing and fixing problems.
Most motors have two voltage settings depending if you connect it as star high voltage or delta low voltage. To give the reader a clear understanding of. Yours should already be wired for the correct voltage.
In case the power switch is defective you must take it to service centre for repair.
Then go to ebay or similar and buy a simple inverter vfd. Most motors have two voltage settings depending if you connect it as star high voltage or delta low voltage. Check the battery voltage and make sure it falls in the nominal operating voltage of the inverter. The few possible causes for the same include tripped inverter battery disconnected battery terminals loose weak battery discharged battery or battery terminals are reversed etc.
