Hey guys,
New around here but I found a thread from last year talking about some of the wiring for the CT sensors but it didn’t quite answer all of my questions.
I have 3 of the latest generation inverters, 2 - 2000w that will be connecting to 5500w worth of panels and a 1000w that’s connected to my 200ah 48v battery bank powered by 2000w of panels.
I’m not an electrical engineer by any means but I do a fair bit of electrical at my day job (industrial maintenance) so I have a decent level of understanding.
1. Can I use the same 2 CT sensors for 3 outputs? I’ve seen many people do 2 outputs but not 3.
2. How should I wire these? Parallel or Series ? (I’m using the CT sensors that came with the inverters)
3. Can someone post a picture of how they wired theirs together?
4. With two sensors reading both L1/L2, assuming they aren’t balanced, what should the inverter be displaying? Should it be reading the total incoming from both lines or should it read the lower/higher of the two or an average? For instance say L1 is 1000 watts and L2 is 2500 watts, what should I be seeing on the inverter as the read out?
5. I was playing around last night and two would read a negative number and the other would read a positive number, if I flipped sensor 2 would read positive and one would read negative. Are the inverters wired different internally? I know I can swap the wires around and get them all reading positive but then the reading doesn’t match what my Sense power monitor / smart meter says I’m pulling from the grid.
6. Is there any issues having two sets of the CT sensors next to each other on the incoming main? I have my Sense monitor, plus the two for the inverters. Will that cause interference or anything?
That’s all I’ve got for now, I’m just trying to gain more knowledge on how these sensors and inverters work so I can ensure that I don’t backfeed into the grid.
I appreciate any help/information you guys can give me!
