The scenario is based on a small on-grid Solar PV system without DC energy storage.
The purpose was to online monitor all common electricity parameters for each solar panel string to check their working efficiency and status for maintanance.
For site situation, suppose we have 3 inverters, 48 solar panel strings 576 solar panels in total. For each solar panel string consisted of 12 solar panels and connect to a general DC circuit for power distribution. We will target this DC circuit for monitoring. [Rated current 12A DC, rated voltage 600Vdc]. Also, each inverter connect to 16 solar panel strings.
For the places that we gonna install the energy meter and IoT gateway, they are covered by stable 4G signal.
