Answer :
The multimeter used on PV equipment should be true RMS types capable of measuring at least 600 volts AC or DC.
This is based on the voltage readings capacity of the multimeter. The multimeter for measuring AC and DC volts usually comes with between 120-, 240-, 480-, 600- volts AC and 125-, 250-, 600-volts DC.
A multimeter is a common electronic instrument often used by technicians and engineers. It is either in analog or digital form. It is used for measuring any of the voltage, current, and resistance.
Hence, in this case, it is concluded that the correct answer is 600 voltages.
