The power plants can be connected to the grid in two ways:
When configuring the power plant, select
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:
To setup Modbus TCP on Inverter using SetApp:
Note:
The TCP server idle time is 2 minutes. In order to leave the connection open, the request should be made within 2 minutes.
It is important to follow rules above, firstly to set HEMS configurator following Inverter setup due to 2 minutes time frame.
