Measure output voltage: After the inverter is powered on, use a multimeter to measure the AC output voltage. It should match the rated output of the inverter (e.g., 120V or 230V, depending on your region). Check waveform with an oscilloscope: Connect an oscilloscope to the output of the inverter to check the waveform.
Battery condition: If testing with a battery, check the battery's voltage and charge level to make sure it is within the optimal range for the pure sine power inverter. Measure output voltage: After the inverter is powered on, use a multimeter to measure the AC output voltage.
Measure input voltage: Use a multimeter to measure the input voltage of the battery or power supply. Make sure it meets the input voltage requirements of the inverter (e.g., 12V, 24V, 48V).
Consequently, it's necessary to use a true RMS voltmeter (digital multimeter) and current meter (clamp meter). On the secondary side of an inverter, the voltage and current’s fundamental wave includes harmonic components.
Abnormal inverter voltage may indicate a problem with the inverter's internal circuit. The stability of the voltage is particularly important for the normal operation of the appliance, if the input voltage is too low or too high, the inverter may not work properly, resulting in output instability or failure.
If the inverter detects internal faults or anomalies, such as input voltage, output voltage, temperature, load, current, etc. Once these parameters are detected to be outside the preset safe range, the system triggers an alarm that displays an error code through the display.
