Hi,
We want to buy a Powervault Battery/Inverter/charger storage system.

The Powervault must be able to read a current transformer, clipped on to the incoming mains line next to the consumer unit. This current transformer module has an ethernet connection.

The following Powervault datasheet says that the current transformer should be no further than 25m away from the Powervault (at least that's what i think it means?)......
Supposing the Powervault is indeed 25m away from the current clamp at the consumer unit. How would you then wire the current transformer back to the Powervault?...
1...Use a long ethernet cable and somehow weave it through the house?
2....Use "TP links" so that the household mains wiring could be used to carry the current measurement signal back to the powervault?
-------______-----_____---------------------------------
The following video shows the Powervault, and at 13 seconds, you can see the current clamp ethernet cable going into the powervault, its marked "GRID". At 39 seconds, you can see the current transformer module......

It is interesting to have a current transformer with an ethernet connection. Is that a coaxial cable or a 8-pin cat-6 or so cable?

The 25m limitation is not placed by the ethernet interface. The coax has some restrictions but that is less and less common these days.Most of the ethernet networks are now based on twisted pairs.

I am not so sure but I suppose the ethernet link on the gadget is for you to monitor the battery status from your hotel room or the conference room of the board meeting. They will certainly have an app for that!

But anyway, you did not say what is the actual distance you have measured. If it is 26m, perhaps you are safe.

How you are planning to mount the gadget? If you want to mount it on (or close to a wall) how you plan to leave 20cm gap around the perimeter?
