Dec 31, 2024 · When it comes to powering your devices through an inverter, one of the most critical aspects to consider is size—how big an inverter do you need? Whether you''re on an
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.
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.
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).
Record inverter testing data: During the inverter testing process, record various parameters, such as input/output voltage, current, power and waveform quality, in order to analyze the performance state of the inverter.
Since different machines have different frequency and voltage requirements, a circuit known as a converter is used to convert AC current from the power grid to a DC current, and then an inverter is used to convert the DC current to an AC current with the frequency and voltage required by the machinery being driven.
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.
