Hi.
Now in to a second winter with my system consisting of 2x8 440w panel strings on a H1 G2 6KW.
Unfortunately I have some hard shading from neighbouring property at this time of year, but the system dealt with this admirably last year. MPPT adjustments kept output at decent levels and I saw voltages dropping down below 200v at times meaning shaded panels were bypassed.
Fast-forward to this year and numerous firmware updates (I'm on the latest) and the tracking is apalling. One of my strings is currently sitting at 298v with 0.6A going through it. There is one panel in a hard shadow so I'd expect to be seeing something like 2kw+ from this string, not 300w.
Any one else seeing crap low current MPPT tracking now? The lack of release notes makes it difficult to track when they might have broken this, and stepping back through firmware versions with support to get the system functioning correctly again is going to be a nightmare.
I've got lots of images of the shading, and screencaps of the PV details from the app, but unfortunately no notes on firmware versions.
