Assuming you have a basic grasp of electrical circuits, you can easily test whether an inverter is drawing power by using a voltmeter. Begin by checking the voltmeter readings with the inverter switched off.
If the inverter is functional, the voltmeter should show a reading of zero. If the inverter is not functional, the voltmeter will show a reading of 120 volts.
With the inverter switched on, check the voltmeter reading again. If the inverter is functional, the voltmeter should show a reading of 240 volts.
How Much Power Does a 1000w Inverter Draw
Inverters are a crucial component in any off-grid battery or solar system, allowing you to convert from one power source to another (DC to AC power) that can run AC appliances.
But how much power does a 1000w inverter actually draw? The answer may surprise you – while a 1000w inverter is capable of providing a significant amount of power, it doesn’t actually draw that much power from your DC power source.
In fact, a 1000w inverter will only draw around 90 to 105 amps of power from your source, if running on 12V. And with 24V, with the same 1000w inverter; will draw 40 to 52 amps… and so on.
However; it all depends on the voltage and the energy efficiency. So if you’re looking to power a few appliances or lights with your off-grid power system, a 1000w inverter should be more than enough.

How Do You Test an Inverter Power Supply?
To test an inverter power supply, you will need a multimeter. First, set the multimeter to AC voltage and plug it into the outlet. Next, take the black lead and touch it to the common terminal on the inverter. Finally, take the red lead and touch it to the terminal for the voltage you want to measure. The multimeter will give you a reading in volts.
You can also use a digital multimeter (DMM) instead of an analog meter. To do this, turn on your DMM and set it to DC Volts or Current (milliamps). Then use one red probe and one black probe to connect them to your AC source of electricity using wire leads or probes.
If you have an AC power supply that is not working properly or if you are not sure what type of output voltage your inverter has, then you should first test its output with an oscilloscope (electronic voltmeter). Oscilloscopes can be used to measure AC voltages as well as DC voltages with very high accuracy and precision.
