I'm running the FLEXmax 60 near its maximum voltage and the cooling fans would go on early in the morning. The noise from the fans didn't bother me as much as the heat buildup in the controller. So, I removed the bottom cover plate from the controller. At the bottom, I utilized the existing screw hole to mount an L bracket, attached a 3" computer fan to the other end of the bracket and bent the bracket upwards slightly so the air would blow inside the controller. There is a 12V AUX connection inside the controller you could use for a 12VDC fan, although I did not do so. Now, the controller fans never go on and the units run MUCH cooler.

jnh, thanks for the photo. The high pitch audio noise is only there when the cooling fan is running. I am almost convinced it is the horizontal grill, which causes the sound.

But right now, we are still not running the equipment, we still don't have permission by the utility, Southern California Edison, to interconnect. We are trying several channels at the Public Utilities Commission. Our original complaint at the PUC was returned with an explanation from Edison why we can not interconnect. The PUC just accepted Edison's answer and did no own investigation. Interesting enough, one of the documents Edison quotes does, according to the California Energy Commission, not apply to our system. The second document, Edison's Net Metering document, is full of errors, and the paragraph they refer to has nothing about batteries. My husband and I weeded through both documents and submitted an appeal with new evidence, and additional letters from one of Outback's presidents and our installer. Sadly, it looks like neither Edison, nor the Public Utilities Commission nor the Energy Commission has people who understand PV systems with battery backup. Edison "defines" batteries to be "generators", and therefore they are non-renewable and more equal to a coal-fired or nuclear power plant!!!! The lack of understanding of the equipment at the Public Utilities and the Energy Commission does not help to solve the confusion, and we are paying taxes to pay their salaries!
Our installer went to Intersolar conference last week and spread the news quite successfully. Our group of frustrated customers and installers created a flyer which caught people's attention. Outback, Schneider and SMA were going to send representatives to a hearing at the PUC today. We have not heard back yet. Our installer also met one of the policy makers, who was involved in the creation of the net metering arrangements. He was very interested in the recent development and offered his help. There are roughly 100 installed PV systems in limbo right now. What a waste!
In the meantime, there is a big push by PG&E, another California utility, and Southern California Edison to end the current net metering program. As it looks right now, it could go away as early as 2015.
