Are they available in a wearable version?Teenage repellers….. haaaaaaaaaaaaaa ?

I checked the Tigo app. Every single Tigo optimizer is producing. Any issue with a single optimizer would have shown up on the Tigo app display.You need to isolate this problem to either Growatt or Tigo. Try connecting another array to that MPPT input.
I saw this comment from a Growatt user.....
"Love everything about it except it generates RFI and EMI (radio and electromagnet frequency interference) . So if you care about radio reception or polluting the electromagnet spectrum, do not buy this. Do some research on MPPT chargers and RFI/EMI. I wish I had not bought and installed. I leave it off almost all the time because of the noise it generates."
In addition, I would bypass all Tigos to make sure faulty MPPT does not damage them. Verify that noise is gone then reconnect Tigos.Connect known good array to that MPPT input, do not connect this problematic array to another MPPT since that risks damaging another MPPT input in case your problem is with this higher voltage array.
Wrong sort of "noise", RFI and EMI is definitely not audible.
I appreciate all the responses. I waited to proceed with the troubleshooting steps due to doubts about proper inverter settings. See the response I just posted.Suggestions on troubleshooting have been given.
If you don't intend to attempt finding the issue. I'm not sure how we can help any further.
"Basically all the mppts were trying to match voltage causing the current to be significantly skewed for your higher voltage strings (PV2 and 3).
It didnt't throw an error because all values were still within the inverter's range."
Volume lolDid the tech say which settings they adjusted??
No. He just allowed full voltage/current flow.Did the tech say which settings they adjusted??
