====== Power plant connection ======

The power plants can be connected to the grid in two ways:
 
|< 700px >|
^  serial with grid power sensor  |^  parallel with grid power sensor  |
|  {{ wiki:20_rdc_charger:connected_power_plant_in.png?direct400 |}}  ||  {{ wiki:20_rdc_charger:connected_power_plant_ex.png?direct400 |}} |

When configuring the power plant, select
   ***in**: serial (**in**ternal) with grid power sensor
   ***ex**: parallel (**ex**ternal) with grid power sensor
Power plants are configured as internal by default.

Obtaining data (power, voltage, etc...) from power plants is possible in two ways:\\
1. adding [[wiki:20_rdc_charger:35_commissioning:01_power_sensor|power sensor]] to measure produced electricity\\
2. connecting PV inverter via Modbus TCP (for SolarEdge inverters only)

Add inverter using configurator:
  *   [[wiki:20_rdc_charger:30_software:start#settings|settings]] page -> meter -> select 'SolarEdge',
      {{wiki:20_rdc_charger:pv_settings_01.png?direct&700|}}\\
  *   [[wiki:20_rdc_charger:30_software:start#io_mux|io mux]] page -> Slave device IP address -> IP address -> set IP address of inverter (inverter must have static IP)
{{wiki:20_rdc_charger:pv_settings_02.png?direct&300|}}


Setup Modbus TCP on Inverter side using SolarEdge SetApp:
  *   Select Site Communication menu 
     * RS485-1 -> Protocol -> SunSpec (Non-SE Logger)
     * RS485-1 -> Device ID, enter address 1
     * Modbus TCP -> Enable
     * set TCP port -> 502

**Note**:\\ The TCP server idle time is 2 minutes. In order to leave the connection open, the request should be made within 2 minutes.\\ 
First, add inverter to Configurator, then setup Inverter by SetApp!
