I recently worked on a Sunny Island/Sunny Boy system in a nearby island, that powered and protected a complete Home Automation system, including the airco system keeping it cool. I had to restart the Sunny Islands to sort out a COMS problem, which revealed some IT issues. It turns out the Sunny Island system had kept it all running smoothly for about four years without an issue so no-one had realized some of the firmware was crunched. I would get rid of the UPS altogether and that ends the problem.
