That number of panels in one string would produce an over voltage for the 3000HF. You would have to wire for two strings to keep the voltage within the operational range. This can be done by wiring the two strings directly back to the two string inputs on the inverter (still only one MPPT...
I have used them about four times and they work a treat. There is a very useful feature in that the same limpet can be configured for horizontal or vertical rails very simply. The materials used are all certified, I believe, but have a look on their website and contact them if you want...
The Fronius 3.6TL has a USB socket and you can download data from the inverter. There is a piece of free software from Fronius called Solar.Access which can import the data from the USB stick and gives quite a nice display. It is obviously not real time but it is cheap and free.
I have used...
You could try using Enecsys micro inverters, one per panel. Dont know if your panels are compatable but give them a call. They are very helpful. You do need to pass a telephone interview with them to be able to buy any.
Sounds like voltage optimisation to me. Probably a VPHASE www.vphase.co.uk or VO4 Voltage http://vo4home.com/index.html. The technology has been around in industry for years. Basically smoothes out supply to 220v and saves you paying for higher voltages you don't necessarily need
