Connection and configuration
Connecting an external energy meter
The product is compatible with the following energy meters:
- Siemens PAC1600 7KT1661 (The energy meter incl. the current transformer and instructions can be ordered from MENNEKES using part no. 18626.)
- TQ Energy Manager EM 420 / KOSTAL Smart Energy Meter
- Install the external energy meter in the upstream electrical installation.
- Connect the energy meter and the product with a data cable.
Configuration
For solar charging, the following settings have to be made using DIP switches:
DIP switch (bank S1) | Required configuration | Brief description |
|---|---|---|
4 | ON | Using Modbus RTU |
5 | OFF | Master |
6 | Dependent on energy meter |
|
7 | ON | Solar charging activated |
Configuration tool:
If the energy meter is to measure external consumers only, an additional setting has to be made in the configuration tool (“Meter measuring point” parameter).
Blackout protection:
Blackout protection is enabled automatically for solar charging, which is why the max. amperage provided by the building connection must also be set via the DIP switches.
Selecting the charging mode
Press the Sun button (1) to select the charging mode according to the following diagram.
The set charging mode is indicated by the “Sun” (2) LED:
