3.1.1. Configuration options

The configuration option of either Grid Meter, PV Inverter, Generator or AC Meter is set in the GX device. That selection will effect
how the system should be wired, and how the information received from the meter is displayed on the screen.
See below diagrams for the different wiring options:
When used to measure a PV Inverter, terminals 1, 2 and 3 should face the PV inverter to ensure correct
direction of current and power.
On the GX device go to the grid meter in the Wired AC sensor settings. Make sure 'Phase type' is set to 'Single phase' and 'PV
inverter on phase 2' is enabled.
