Please consider adding a VOLTAGE METER that works just like the existing POWER METER, but for voltage only (L1 to L2).
The Voltage delivered from the power company varies greatly throughout the day, and I’d love to be able to track it. Furthermore, I have a 20KW solar array and want to be able to determine voltage drop between the meter and the micro inverters in the arrays. I’m already able to track/monitor the voltage each inverter sees, but I short of connecting a volt meter at the meter and write the down the values, I don’t have a way of plotting the voltage over time.
As you can see, my voltage fluctuates a lot, so determining how much is due to voltage drop (rise) vs. the voltage coming from the utility would be very helpful.
