 The REL200100000 is the EM24DINAV93XISX from Carlo Gavazzi. Other EM24 models from Carlo Gavazzi can also be used, as the communication is the same. For example the EM24DINAV53DISX,​ which uses Current Transformers and can therefore work in systems > 63A per phase, has been tested and works. Note that this model is not stocked by Victron Energy, we recommend to purchase it locally. The REL200100000 is the EM24DINAV93XISX from Carlo Gavazzi.

 To measure a single phase PV inverter in a 3-phase system, connect all 3 phases to the grid phasing terminals (3, 6 and 9). Now you can chose on which phase you want the PV inverter by connecting the L1 line of the PV inverter to terminal 1, 4 or 7. To measure a single phase PV inverter in a 3-phase system, connect all 3 phases to the grid phasing terminals (3, 6 and 9).
