Re: How to test Converter voltage Hi! Checking the voltage on the battery cables, even when they are disconnected from the battery, can give you an idea of what voltage is coming from the converter. However, please note that this may not give the full picture since the converter may have built-in voltage regulation and you will not get the exact voltage that the converter supplies to the output. Use a multimeter to measure voltage. Disconnect the cables from the battery, set up the multimeter, set the multimeter to DC voltage (DCV) mode, connect the multimeter to the cables, turn on the converter, or turn on the power system. The voltage on the multimeter will indicate how much power is being supplied from the inverter.
