I would like to monitor the DC Voltage

I would like to monitor the DC Voltage of up to 600V of a PV Solar Battery. Any suggestion on what sensor to use and how to wire it up? [Note: I know it is hazardous voltage & highly expert area requires professional help. I'd like to explore what it will look like for an isolation to work on such voltages]

Hi Umesh, a simple method is just a resistor divider to bring the voltage down to the safe level of your A/D input. For safety, consider following that with an analog optocoupler to provide an isolation barrier between your high voltage and low voltage circuits.

Hi Mike, thank you! I'll use Optocoupler ICs between the HV and LV circuits. Also, found IVT-S from Isabellenhuette to make it easy. I agree, it's an expensive part to consider for this task
