The basic project of a local SCADA system for a solar power station is built using a ready-made Application Set distributed by Copa Data.

The necessary minimum has been implemented to ensure the operation of the power station:

Dashboard with general information about the station: current power, energy meters, list of inverters, and their status;
Panel with extended inverter information: power, AC and DC currents, voltages, amount of generated electrical energy, serial number, decoding of status and error registers;
Single Line Diagram (SLD) with monitoring of the substations: power, import/export energy meters, currents, voltages (over 50 parameters), and transformer temperature;
Control of operating modes for both the entire station and each inverter individually;
Logging of alarms and events;
Historian;
Trends.

Additionally, network equipment configuration, remote access setup, and network monitoring have been implemented using Zabbix/Grafana.
