Economic Report with EM24

Hi Everyone,

I get my daily economic report emailed to me via VRM every morning. I have the EM24 meter for providing me with grid data across the three phases.

I would like to know if there is a way that my economic report can provide me with a grid usage (in kWh) on each phase? Currently it just gives me the combined usage of all the phases.

I find this to be useful as breaking cost down to a phase level allows greater incite into usage demands.

Cheers!

EM24 Ethernet für Anzeige PV-Produktion?

Hallo zusammen,

kann ich einen EM24 Ethernet nutzen, um die PV-Produktion einer bestehenden AC-gekoppelten Einspeise- und Eigenverbrauchsanlage im VRM zu visualisieren?

Ich habe 3 (einphasige) Wechselrichter, die jeweils auf eine "Hausphase" einspeisen. Kann ich da einen EM24 nutzen, oder muss ich jeden Wechselrichter einzeln messen?


Meine Victron-Anlage im ESS-Modus:

- Multiplus II

- MPPT Smart Solar

- EM24 Ethernet als Gridmeter

- Cerbo GX

- SmartShunt

- Lifepo4 Batterie


Vielen Dank

Chris

EM24 RS485 on 120/240V split phase loses its settings

We set the EM24 meter to mode E (application E?), split phase 120/240V. ESS mode operates fine (i.e. the inverters feed power upstream without feeding power into the grid), but the meter loses its settings, but after a few seconds, it looks as if the Venus changes the settings of the EM24 to three phase and the system starts to behave erratically.

EM24 Ethernet - lockup issue

Hi Everyone,

I am running an ESS, everything fine, BUT: My EM24 Ethernet is regularly losing the connection to the LAN. This is not a DHCP issue or such, it clearly hangs.

After disconnecting the EM24 from power (cold restart) it works again, but only for 1-2 weeks.

I would like to update the firmware and then see whether the problem goes away. This is just a way of saving time from further troubleshooting.


My problem is: Nobody will help me to get newer firmware. Victron Dealer says to contact Carlo Gavazzi. They say to contact Victron. And Victron says to contact the Dealer. Stuck in a loop.

Anyone here to help my get new firmware for the EM24 Ethernet?

My Device is a EM24-DIN.AV2.3.X.E1.X


thanks

Incorrect energy display in VRM portal - MultiPlus II with EM24

I currently have the following phenomenon:

In the VRM Portal the displayed sum value of the energy meter jumps between a few watts, the current power of a phase and the correct total power (see image 1).

Via the remote console, the correct value is always displayed (in the system schema as well as on the overview page).


System setup:

1 MultiPlus II GX FW: 2.72

Connection mains parallel to AC1

Energy meter EM24 Ethernet FW1.6.48 - use phase balancing 3P.n


- AC coupled PV system with power feed-in

- ESS with external meter

1) example Remote Display & VRM Dashboard with different energy sum

2) example VRM Dashboard correct sum energy

3) example VRM energy meter log

How to get an EM24 CG Energy Meter showing under the 'Energy meter' list.

Hi,

Installed an ESS system. Have an EM24 (Ethernet) Energy Meter to regulate.

Its visible on the CERBO GX device list, but not under the energy meter list.

I am also unable to see the grid on the far left of the home screen on the Touch Display, and the AC figures are not correct.

The energy meter is on the network, seems to be communicating correctly, as we are able to see load figures.

Has anyone else experienced the same issue, and managed to overcome ?

Thank you


The system is showing the energy meter on the list of equipment

[image]

(Its present in the device list on VRM)

[image]


(And it all seems connected ok)

But for some reason it’s not showing under energy meters

[image]

I have seen on some feeds on the community that people have an image of the grid in the top right, I have the red box but no info and all the AC loads show 0W.

Nulleinspeisung mit Phasenkompensation mit Gavazzi EM24 an MultiplusII 48/5000/70 single phase mit Pylontech Akku

Hallo Community, ich habe eine Frage bezüglich meiner Anlagenplanung.

Ich möchte gerne meine zukünftige PV Anlage (4,8 KWp) über den WR Multi+II 48/5000/70 + MPP150/100 und Cerbo GX mit 4 Pylontech 2000er Akkus einphasig (L1) ans bayrische Stromnetz mit dem EM24 durch Ausnutzung der Phasenkompensation anschließen. 63A Hausanschluss.

Es soll keine Einspeisung erfolgen. ("Nulleinspeisung")

Vorrangig sollen die Akkus nur über PV geladen werden und bis ca. 50% Entladung Phasenkomensation machen.

Soweit ich gesehen habe benötige ich dazu eine moderne Messeinrichtung mit Zweiwegezähler und Stammdateneintragung.

Ich habe Fragen bezüglich eines Netzausfalls.

- Was passiert im Fall der Notstromversorgung bei Netzausfall auf den kompensierten Phasen ? Wird dann nur noch L1 notstrombedient ? Wie hoch wäre dann die max. Belastung auf L1 ?

Oder wird nur die AC-Notstromdose (critical) des WR z.b. für Hausbeleuchtung oder Pumpensteuerung für eine Heizung bedient ?

- bei normalen Betrieb mit Kompensation liegt die Spannungsdifferenz zwischen den Phasen bei 400V. Wie reagiert der WR bei Netzausfall und was wird passieren wenn das Netz zurückkommt bezüglich der Hausfrequenz.

Ich freue mich auf ein feedback

Octo GX & EM24 Energy meter connection, separate USB RS485 required?

Hi !

Does the Octo GX require an USB-RS485 converter to read the EM24 energy meter or can i connect the EM24 directly to the Octo GX A,B terminals?

Thanks for your feedback!

ESS ohne Netzeinspeisung, EM24 benötigt ?

Hallo zusammen, folgendes Problem:


Mein System:

MultiPlus-II

MPPT150/35

Venus GX

3x Pylontech Batterie

Solarleistung max 2000W

Eingestellt als ESS. Die Software ist aktuell, Update erst durchgeführt.

Da der Energieversorger mir einen neuen Zähler eingebaut hat der nun auch den eingespeisten Strom ins Netz zählt ist mir aufgefallen das der Multiplus2 nach voller Ladung der Akkus und Stromüberschuss ab und zu minimalen Strom ins Netz einspeist, was ich nicht möchte. Ich habe im Multiplus die Netzeinspeisung Aus gestellt. Würde mir ein Energiezähler wie der EM24 hier weiter helfen ? Kommuniziert dieser mit dem Multiplus2 so das absolut kein Strom mehr eingespeist wird ? Oder gibt es eine andere Möglichkeit die Einspeisung zu 100% zu verhindern ?

Vielen Dank für eure Hilfe

ET340 oder EM24 für Phasenkompensation mit einem Multiplus 48/5000
Hello,

At the moment nobody can tell me exactly what kind of energy meter (ET340 or EM24) I should use for phase compensation.

I have a Multiplus 48/5000 in island mode. The ESS would like to use the phase compensation and the connection to the public grid.

As far as I know, the ET340 is newer and measures all 3 phases individually. But there should be problems with this. In many forums the suggestion is made that one should switch to the EM24.

What's the right way now?

I would appreciate an expert statement.

Best regards

Thomas

EM 24 on 3 phase supply 100 amp + per phase 150 meters away from MultiPlus 24/5000 and CCGX

Hi guys

I was directed to this forum by Victron dealer for my query to be answered

I need to confirm if EM 24 will work in our set up as expected
We currently run MultiPlus 24/5000
with 24volt 920 amp traction battery on CCGX to power the house
House supply is temporary abounded but there is a private 3phase cable 150 meter long from industrial building to the house
House is connected to L1 ( PV from L1 on input side of the Multi)
Industrial building has 80 kw PV on the roof together with 3 SMA inverters 50, 20 and 10 kw
Most of the PV power is exported to the grid

So in the day time there is ample of power to cover all the loads in the industrial building and the house
But charging is only possible by scheduled charging which is not most efficient
Can we install EM 24 in the industrial
building 150 meters away from the house (MultiPlus CCGX and battery) on current transformers as the connection is over 100 amp per phase
There is also Ethernet connection
Between house and industrial building and CCGX can see and display all SMA inverters but can’t
Use this information for efficient charging
Can CCGX see the EM 24 in current set up as it see SMA inverters and
Use this information to utilise only available PV for loads and charging in ESS
Can it work with ct’s ?

Thanks in advance for any advice

Multiple Grid Meter's on same site

Hi

I am wondering if I set up a site with 2 x EM24 Meters set-up as "Grid Meter' will the consumption of both meter's be combined together in the main controller?

I have a house and shed both fed separately from a meter panel that is inaccessible via wireless hence the need for 2 consumption readings.

EM24 stopped sending data after lightning

I've an EM24 feeding a GX Color Control and a Multiplus charging some batteries. We had a dreadful thunderstorm a few weeks back after which the GX hasn't got any information from the EM24 which is acting as a Grid Meter. The Red/green lights are flashing on the USB connector on the Color Control. I suspect that maybe the EM24 has freaked and maybe its settings have changed. I've tried changing the Modbus address to 2 and 30 (the lowest on the GX). I've also been poking around the menus on the EM24 and noticed it's set to Applicat Type H which looks a bit odd but I can't work out what it should be. I've seen the manual but don't really understand/know what I'm looking for. Any suggestions?

Edited to add that one reason I'm suspicious of the EM24 is that it seems to think we're running 166 Volts - see picture.
