ESS with EM24 Ethernet

Hello,

I am trying to setup a ESS system with one Multiplus-2 GX and two Multiplus-2 and one EM24 Ethernet Energy meter. I thought it is a brilliant idea to work with the Ethernet Version of EM24. But I am afraid I failed.;-) The documentation which came along with the product looks like a manual of IKEA to set up a storage rack Billy. On this piece of paper there aren't any information for setting up network details. I would be satisfied to simply change DHCP from OFF to ON or to setup in detail IP-adress, gateway etc. - but nothing at all.

With some research in internet I found a document which gives more in detail information for this. But my brain is to small to get how to manage. I was playing with the menu on the energy meter for more than 90 minutes but no chance to change IP settings or to switch DHCP ON.

Please help! Any hints and recommendation are welcome!

CT clamp energy meter via ethernet for multiplus ii single phase (UK)

I'm finding it hard to get facts on the following.

On the ESS manual it states there is a CT clamp sensor EM24 I think, bit I can't find any reference to the fact it uses CT clamps, rather than being an inline sensor.


The document states you can use the 3 phase version for a single phase, again when you find the product online it's got no reference to this.


Has anyone got any experience here?

  • I need to not interfere with the meter wiring.
  • Want to self consume and not feed in.
  • Consumer box 20m as the wire runs from MP2 location
  • Thus ethernet or serial if I can extend it is needed.
  • Also an option to use Arduino to sense and relay over Ethernet a standard CT clamp.

My next question while anyone is listening,

Can I schedule battery charging between 0000 and 0700 only with the MP2 GX / with a cerbo ?

.POE from Cerbo

POE from Cerbo, has any one used a wifi to ethernet adaptor to solve the poor cerbo wifi reception when in a cabinet whilst maintaining the Ip rating of the cabinet, thinking of trying this product https://www.tp-link.com/us/business-networking/outdoor-radio/cpe210/ in client mode with or without a poe injector for about a third of the cost of the other wifi based solutions and you don't need to source external antennas etc that are compatible with the dongles

Local area network Cerbo access

Is it possible to access the Cerbo GX using the Victron Connect mobile app (or computer) using ethernet or WiFi (not Bluetooth or VRM)? My installation will be beyond BT's reach and when we lose mains power our internet (cable) goes out so I won't have access to VRM. I would like to monitor the system from my home which is 100's of feet away but still reachable from my local area network.

Victron MultiPlus II GX

We have a number of MultiPlus ii GX units installed and we remotely monitor these units on a closed network. We see events where the Ethernet connections are lost for around 20 minutes for 2 minute intervals and then returns without issue. We know this because our switches record port down and up. We have 4 units all at different locations all doing similar. The Ethernet to the locations is not impacted as there is more IP connected equipment on site that has no interruptions. Appreciate any help that can be provided. They are all running latest release firmware. They have only been in for 1 month.

3 Quattros in parallel, communication problem

I'm using three Victron Quattro 48/10000/140-100/100 installed in parallel. Each of them are connected with self-made UTP Cat 5 cables in daisy chain configuration. When I tried to connect the inverters from VEconfigure, the software says "MK3 detected" but after loading for a few seconds, an error message appears which says "error during communication". Any idea what the problem is and how I can solve it? Thanks.

Navico App Control

Hi

Anyone know if any progress has been made, or can be made, with the Victron app on Navico NSO plotters and the support for non-touchscreen inputs?

We have an NSO evo2 onboard but not attached to Simrad screens so, therefore, no touchscreen input just the OP50 control or keyboard and mouse.

Suspect this is common in a lot of glass bridge installations on larger vessels.

Thanks, Jon

CCGX ethernet MAC address changing (link-local)
I am attempting to use the ethernet MAC address of CCGX to determine it's IP on a DHCP network. The CCGX is running firmware v2.53.


Our device is acting as the DHCP server in this case, and the MAC address we see in the arp table for the CCGX changes back and forth between two addresses. Sometimes the MAC appears correctly, with a prefix of 'c4:f3:12' which matches the value reported on the console display and by ifconfig on the CCGX for the eth0 interface. However, sometimes we are seeing what appears to be a random address (changing on reboot), for example with a prefix of '56:e8:21'.

This second value corresponds with the MAC shown on the link-local (ll-eth0) MAC address shown by ifconfig on the CCGX. Which looks like it was added as part of this issue: https://github.com/victronenergy/venus/issues/361

My guess as to why we're seeing the other MAC is that the CCGX is sending packets out over this link-local interface, even though it has a valid DHCP IP address. Do you have any suggestions? We would ideally like to see only the 'real' eth0 MAC address once it has a DHCP IP so we can easily identify it.
