Energy Meter EM24 manual
1. Introduction and usage
This document is the manual for the EM24 three phase max 65 A per phase Energy Meter. As shown
in the picture above.

The Energy Meter can be used for four things:
1.
Grid meter, and used as control input for an
2.
Measure the output of a PV Inverter
3.
Measure the output of a AC Genset
4.
(deprecated) Grid meter, used as control input for a
(1) In case the meter is used as a grid meter in a single phase installation, it is possible to use the
second phase to measure the output of a PV Inverter. Note that this does not work properly, use the
ET340 instead. See
Energy Meters FAQ, Q5
The meter is connected to the Color Control GX. There are two options in its wiring:
1.
Direct connection, either using the RS485 to USB interface with 1.8m cable length, or the 5.0m
cable.
2.
Wireless connection via Zigbee
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
