Try running it along the route more or less as you intend later on for a test run. When you stretch out the cable you turn it into a long antenna. It may or may not become an issue. Also shielding the cable may help, or using an old coax cable (TV antenna cable, or audio cable, for the cheap version). I'm not really sure though, since the "twistiness" of the TP cable should counteract noise (all increased voltage on the brown at a point in the cable should also be added to the brown/white, so the differential between the two should stay the same).
Working in IT you might have access to shielded network cable, that will help with noise. connect only one end of the shield to battery negative. some single pair phone cable is also shielded. a long cable would lean more towards a lower frequency antenna, and it is dealing with 50Hz mains so could pick up mains hum from power lines in the area, hopefully they are not parallel with you CT clamp cable. you could try a capacitor say a few picofarad across the end closest to the inverter. Just ideas and its working quite well as it is so might not be worth it.
in the handbook it says you can have the clamp upto 30m away. i just used some thin speaker wire that was 30m, its working sweet as, but what i want to know is how do you run 2 or more units at the same time all set to limit oO do i have to run 2x the cable or could i just splice the cable i have and have one clamp feeding all inverters
Hi , great video , thank you . do you have link or list for those parts you used ? and is there a way to connect two sensors instead of one ? in the usa we have two wires each has 120v , so boh need to be monitored and each need a ct clamp . ? thank you
Is it possible to have 2 of these inverters running.. example: one for a pool pump (ct clamp on pump braker) and the other on the house main box? Is that doable? (Pity you can't adjust in menu for the cable length gain).
By chance, would you know the inside diameter of the sensor clamp ? I've looked high and low on-line and even asked the question to an ebay seller - without results--- (I've heard they are celebrating the Chinese New Year) I want to be sure it will go around my incoming wires from the meter (which are huge)
Very ture but i ended up buying it anyways as my CT cable was 20m and i was getting about 90% rather than say 100% if i had a short CT cable. Eg if the house load was 200watts the grid-tie with limter and 20m CT cable read it as 150watts ish so the 50w came from the grid, depending on the house load eg the fridge it would be out by more. However at higher loads it was better just the very low loads it couldnt read well. I will be doing a video of the External unit soon so stay turned :)
