What to do if my Sincro Inverter has no voltage?
- D
  Deanna AnthonyAug 9, 2025
  If your Sincro Inverter shows no voltage, several issues could be the cause. First, check all connections to ensure they are secure. A faulty AVR could be the problem; check the fuse and consider replacing the AVR. Also, inspect the rectifier bridge. An open stator exciter circuit or a main winding fault could also be responsible; check the stator/rotor windings resistances and insulation. In some cases, the machine may be demagnetized; excite the alternator by applying a 6-12 voltage across the exciter terminals for a second, respecting the polarities while the engine is running.

Why is my Sincro Inverter voltage so low?
- P
  Pamela WashingtonAug 17, 2025
  If your Sincro Inverter is showing low voltage, try these steps: * Adjust the voltage using the potentiometer «V» on the AVR to set the reference voltage to the desired value. * Check and adjust the under-frequency protection value for the nominal frequency (50Hz or 60Hz). * Verify the engine speed to ensure it is correct, as a low engine speed can cause low voltage. * If these steps don't work, the AVR may be faulty and need replacement.

What causes high voltage in a Sincro SK160 WB Inverter?
- B
  browndavidAug 25, 2025
  If your Sincro Inverter is producing high voltage, the issue may stem from several causes. Begin by adjusting the voltage with the potentiometer «V» on the AVR to ensure the reference voltage is correctly set. Check the sensing connections to rule out an open circuit. If the problem persists, the AVR may be faulty and require replacement.

How to fix unstable voltage on a Sincro Inverter?
- C
  Christina GallegosSep 1, 2025
  If your Sincro Inverter's voltage is unstable, there are a few things you can check. First, make sure the AVR stability is correctly set by checking the correct Dip switches position and adjusting stability with the ST trimmer. Also, check for oscillations in engine speed using a frequency meter. If these steps don't resolve the issue, the AVR may be faulty and need to be replaced.
