How to take a comms connection back to battery storage system?

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......
