Jul 28, 2019 · My solar power system contains a lead-acid battery but as soon as I use the inverter to power some load, the voltage drops instantly by 1 volt.
The cable between the inverter and the motor is too long, causing voltage drops. Incorrect parameter settings that do not match the actual load. Solutions: Check and reduce the motor load if necessary. Inspect the mechanical system to ensure the motor is not blocked. Set an appropriate current limit based on the load.
Cause: When multiple inverters start or work at the same time, the grid voltage will drop briefly. When the voltage drop lasts longer than the time allowed by the inverter (generally, the inverter has a minimum allowable voltage drop time), it will cause an undervoltage fault of the inverter.
Once you have identified the problem, you can begin troubleshooting it. Here are some steps to follow: Check the input voltage. The input voltage to the inverter should be within the specified range. If the input voltage is too low or too high, the inverter may not function properly. Check the output voltage and frequency.
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.
Whenever PWM is employed in an inverter for enabling a sine wave output, inverter voltage drop becomes a major issue, especially if the parameters are not calculated correctly. In this website you might have come across many sine wave and pure sine wave inverter concepts using PWM feeds or SPWM integrations.
Countermeasure: The DC voltage upper limit of the inverter is generally set at a voltage of more than 700V, which is equivalent to an input AC power voltage of about 500V, which is more than 30% higher than 380V. This situation rarely occurs. Short-term power supply overvoltage can be prevented by installing an AC reactor. 1.
