The power plants can be connected to the grid in two ways:

serial with grid power sensor		parallel with grid power sensor

When configuring the power plant, select

• in: serial (internal) with grid power sensor
• ex: parallel (external) with grid power sensor

The power plants are configured as internal by default.

Obtaining relevant data from photovoltaic is possible by two ways:
1. adding power-sensor to measure produced electricity by PV (no connection to interver) - on how to add power sensor please see Power Sensor
2. connecting PV inverter by Modbus TCP to EVSE (only for SolarEdge inverters)

To add inverter on HEMS configurator:

• on settings page inside source table, select SolarEdge inverter. Please see limiter
• on io mux page define IP address for inverter. Please see software

To setup Modbus TCP on Inverter using SetApp:

• Select Site Communication menu
  • RS485-1 → Protocol → SunSpec (Non-SE Logger)
  • RS485-1 → Device ID, and enter the number 1.
  • Select Modbus TCP and set to Enable.
  • To modify the *TCP port, select Port, set the port number to 502.

*TCP port is 1502 by default.
