[QUOTE="johnb2713, post: 554140, member: 35153"] Assuming that you mean the CT when you say coil. The CT is used to detect current flow on the incoming grid supply, the inverter uses the information to increase it's voltage output (if import was taking place) or decrease it's output voltage (if export was taking place). The problem with CT's is that they generally operate around zero current (thats the aim) at zero current they have zero output, noise on the cables can have a significant affect on the inverter performance. My Victron inverter had a 2 metre cable on the CT that could be extended to 5 metres, I needed to go to 25 metres. I did some trials with screened twisted pair cable and there was little to no noise on the extended cables, the screen being connected at inverter end only. The other option which is probably a better solution is to use a generation meter instead of the CT. Looking at the manual for your inverter (assuming I found the correct model): [ATTACH type="full"]16608[/ATTACH] Being digital information, this would run nicely down your CAT 5 cables and be immune from interference.
