A group object (GO) is a device datapoint. A group address (GA) links it to other KNX devices or a visualisation. Assign group addresses only to the objects needed by the project and match their datatypes to Section 8.
Commissioning checks
| GO | Object | What to check |
|---|---|---|
| 1 | Module status | 0 means normal operation; investigate a non-zero status. |
| 2 | Firmware version | Read the version and check the applicability in Section 11. |
| 24 | AC Power | Compare the value with the inverter display or application. |
| 30 | AC Energy | Compare the accumulated value and units. |
| 42 / 43 | Battery power / SOC | Where supported, enable Battery 1 and compare with the battery state. |
| 55 | Powermeter | Where supported, enable the meter and verify the measurement direction. |
