Jay:
Here is a link <https://millersolar.com/MillerSolar/case_studies/36_SIFortress/36_SunnyIslandFortressIntegration.html> to the study. The web page needs to be updated with this information: There are two settings to be changed in the Sunny Boy Inverters: Backup mode and Default. See Below: I had set the default to OFF_Grid but I had not set the Backup Mode to On All. It was in Off. There is a possibility changing the Backup Mode setting may fix the Frequency Shift Power Control problem that is the root of this dilemma. There have not been enough sunny days to see the PV bring SOC up to the level of near 100% where the problem exhibits. As soon as the weather gets sunnier and the days get longer I will see what happens and report back.

There have been issues, I am sure many of them self-induced. Fortress has been overall very responsive. There have been a few days where I could not get through to technical support but with persistence I always manage. Fortress has offered truck–roll compensation at a reasonable rate as well.

While I see the comments on SunPower and the challenges, are any of you having similar issues with Fortress? Their bms boards from the early classics have not held up and even after replacement there are still issues ( parallel batteries and stand alone not showing accurate #’s, ). While support has been, well supportive, the issues persist. Any thoughts or fixes you have come up with?? I just had a customer unplug the coms cable from their sol-ark and bring their readings to volts VS %% and it is starting to work a bit better. Any and all help or ideas appreciated.
