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.

Note that this product is no longer sold. Use the ET340 for new installations.

The Energy Meter can be used for four things:

Grid meter, and used as control input for an ESS System (1).1.
Measure the output of a PV Inverter2.
Measure the output of a AC Genset3.
(deprecated) Grid meter, used as control input for a Hub-4 system4.

(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 for details.

The meter is connected to the Color Control GX. There are two options in its wiring:

Direct connection, either using the RS485 to USB interface with 1.8m cable length, or the 5.0m1.
cable.
Wireless connection via Zigbee2.

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

2. AC Wiring and front selector

3-phase diagram:

When used to measure a PV Inverter, terminals 1, 4 and 7 should face the PV inverter to ensure
correct direction of current and power.

single phase single function diagram:

Note the jumper between terminals 1 and 4. You do not need this connection if you have the version
AV2 of the sensor:

The diagram shows the wiring when used as a grid meter.

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.

single phase dual function diagram:

In this diagram, a single meter is used to both measure the grid and a single phase PV Inverter.

On the CCGX 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.

Front selector

Change the front selector so it is not in the locked state. This will allow it to be automatically
configured by the rest of the system the meter. The front selector is located next to the display as
indicated in this image:

3. Connection to CCGX

Option A: wireless Zigbee connection

Step 1.

Connect the Zigbee to USB converter to the CCGX using the supplied USB cable. A few seconds after
connecting, the active LED should be on and the TX/RX LED should be blinking (the converter takes its
