Description

The Victron ET112 Energy Meter 1ph max 100A are used in systems with a Venus-device. To measure the output of a PV inverter (more info in the Venus-OS manual here. Or as a Grid Meter in an ESS installation, more information in the ESS manual.

The Victron ET112 (for single phase max. 100A) and the ET340 (for three phase max. 65A) Energy Meters are typically used in an Energy Storage System.  The EM24 is for 3 phase monitoring only.

To measure the power and energy of the whole application at the distribution box. Or to measure the output of a PV Inverter, to display the data on the Color Control GX and the Victron VRM Portal.

First decide if you need single- or three phase meters

For a three phase utility connection, use a three phase meter. For a three phase PV Inverter, use a three phase meter as well. For a single phase utility connection, use a single phase meter. And in an installation with a single phase utility connection, that also has a PV Inverter that needs measuring with a Victron meter, then you can use Rutger 2 pieces of ET112; or use the ET340.

Now, based on current, select the model

Requirement Type Solution
Part number Model Specs
Single phase up to 100A Shunt REL300100000 ET112 1 phase – max 100A
Three phase up to 65A/phase Shunt REL200100000 EM24 3 phase – max 65A/phase
Single phase more than 100A/phase CT Not available, use the three phase CT solution
Three phase more than 65A/phase CTs Carlo Gavazzi EM24DINAV53DISX (see FAQ Q8)

Besides above meters, we also stock the ET340 meter; REL300300000. It counts energy in a different way than the EM24. For Germany and most other countries; the EM24 is the advised model. See FAQ Q5 and Q9 for details.

3. Victron ET112 FAQ

Q1: Can I combine three ET112s for a three phase system?

No. Use a real three-phase meter.

Q2: Can I use other meters, for example from other brands?

No.

Q3: I already have a Fronius SmartGrid meter, can I use that?

No.

Q5: What are the differences between the various three phase meters?

  • EM24 – REL200100000 – Carlo Gavazzi EM24DINAV93XISX
  • ET112 – REL300100000 – Carlo Gavazzi ET112-DIN.AV01.X.S1.X
  • ET340 – REL300300000 – Carlo Gavazzi ET340-DIN.AV23.X.S1.X

Differences:

  • The ET meters don’t have a front selector that the installer needs to put in a different setting than it comes out of the box: easier, less mistakes to be made.
  • The ET meters have no display. The only thing they have is an LED, which blinks in case of active communication.
  • The new meters have 2 RJ45 sockets for the Modbus RS485 connection. But they are not used. Note the possible confusion because of yet another RJ-45 socket in the Victron world though. Don’t mix that with VE.Bus, VE.Can or VE.net. Besides the RJ-45 sockets, the meters still also have screw terminals access below the sockets for the RS485 wiring, which is how we advise to connect a meter to the RS485 to USB interface and then CCGX.
  • Since there is no display, the Modbus address can no longer be changed on the meter. Combining multiple of those meters on one RS485 network is therefore not supported by Victron. You are advised to use multiple RS485 to USB interfaces.

Three-phase new meter only (ET340):

  • Measuring Energy from single phase PV Inverter on the second phase of the new meter, ET340, actually works. Where-as with the old meter, the EM24, only the Power Metering (Watts) works. The Energy Metering (kWh) for a single phase PV Inverter on the second phase of the EM24 does not work.

Q6: Will you keep shipping both 3 phase meters? (ET340 & EM24)

Yes. There are still situations suitable for each. See Q9.

Q7: Can I buy those meters directly from Carlo Gavazzi instead of from you?

Yes. That is also why we make no secret of the CG part numbers.

Q8: I want to use Current Transformers (CTs), is that possible?

Yes. You can buy the CG EM24DINAV53DISX directly from Carlo Gavazzi or one of their distributors. Even though Victron does not stock that type of meter, we do support it in our software.

The EM24DINAV53DISX is the solution for three-phase systems that go over 65A per phase.

Q9: What’s the difference between ET340 and EM24 in 3 phase systems?

These meters have a different way of calculating the total of energy imported and exported.

In the ET340 – the energy imported and exported is counted at each individual phase and then the Total is provided from the sum of those values.

In the EM24 – the energy imported and exported is counted as a total power, with net differential readings from each phase cancelling each other out.

Which meter is best to use with depend on your countries own metering configuration. It is most common in Australia and Germany for example to only be billed for the total in a 3 phase system. So it is more accurate to use an EM24 to match the billing.

So if you are exporting from one phase, and importing from another phase after the energy meter, but before the billing meter then you will not be charged for this, and the meter should not count it as an import and an export.

This is also how Victron’s phase compensation feature works, to make the most of the cost savings for an ESS system when there is a differential in generation and load across different phases.

Q10: Can I use an isolated USB-RS485 interface?

Yes. The interfaces we sell are non isolated; suitable for most use cases.

In case an isolated one is needed; purchase it dirsctly from Hjelmslund Electronics.
