Every system will need at least 1 GEM120 (ID1) meter installing to monitor the import and export of the building. Every GEM120 meter needs a power supply/voltage reference point. This could be a dedicated supply from a 6A, for example.

Every GEM120 meter will need a data connection back to the inverter’s meter communication port. Please see the previous page for the connection point.

Data connection should be a twisted pair cable, for example, Belden multi-stranded cable.

If installing multiple meters, both the data and power supply can be linked together in series.

GEM120 meters come with a split core CT that has a 2m cable.

This must not be cut down or extended.

Press and hold the GEM120CT button to change the ID settings.
