Sep 1, 2018 · Inverter failures result in system downtime and can significantly impact the return on investment (ROI). Therefore, failure modelling of inverters along with panels is critical in
Causes: High or sudden voltage spikes in the power supply. Sudden load stoppage causing voltage feedback to the inverter. Faulty DC capacitors inside the inverter. Solutions: Check the power supply and use a voltage stabilizer if necessary. Configure a proper deceleration setting to prevent sudden stopping. Inspect and replace faulty DC capacitors.
1. Power supply phase loss Cause: When the inverter power supply phase is lost, the three-phase rectification becomes two-phase rectification. After the load is applied, the DC voltage after rectification is low, causing undervoltage failure.
This can arise from high inertia loads decelerating too quickly, the motor turns into a generator and increases the inverter’s DC voltage. There are other causes of DC overvoltage, however. POSSIBLE FIXES: Turn the overvoltage controller is on. Check supply voltage for constant or transient high voltage. Increase deceleration time.
Inverter failure of grid loss failure When the inverter cannot detect the voltage on the AC side or the detected voltage value is too low, the inverter reports a inverter failure of grid loss failure. Common causes and solutions for grid loss faults reported by the inverter are as follows: Check whether the nearby electrical equipment can work.
Faulty DC capacitors inside the inverter. Solutions: Check the power supply and use a voltage stabilizer if necessary. Configure a proper deceleration setting to prevent sudden stopping. Inspect and replace faulty DC capacitors. 3. Troubleshooting Undervoltage
