I installed Sense a couple of weeks ago, but couldn’t install the Solar module as my solar feed is combined with the utility feed in my whole-house generator’s transfer switch panel on the outside of my house and I had to order an extension cord from Sense for the solar inductive pick-up clamps. I am using the main solar cut-off for firefighters, also on the outside of the house, to turn off the ganged inverters during set-up as it powers-down the two inverters (my 13.5 KWDC system was too large for one from SolarEdge at the time) as well as entirely breaking the feed from inverters to the merge point in the adjacent box.
Each of the five times I tried, I made certain that my PV system was steadily outputting. It’s the afternoon, but I still had from 1.5KWAC to 3.5KWAC. Each time I tried, I got the “Unknown Error” screen in the set-up dialog on my phone whilst the dialog was waiting to sense the solar feed dropping.
I then read these posts, went back outside, took the box apart and tried once again, this to make certain installing the barrier in the box wasn’t opening one of the inductive clamps and that the clamps were polarized properly, which they are. But still no luck. Does anyone have any ideas? I’ve already sent this as a tech support request, but I thought I’d ask here, anyhow, just in case.
