Yes you are correct, everyone has their own goals. The problem with the inverter is that the control system is so complex that the effort/reward for the 'community' is too high and I don't think it would ever be used other than as an interesting talking point.
The generic controllers are great if you just want to connect up and run with whatever you have built, I have one running on a system with under floor heating and it seems to work fine. The downside is you have no control or possibility of extending/experimenting etc. but as a basic quick cheap solution they seem to work fine.
I've now got my own 'home made' controller up and running so for anyone who wants that level of control complete with web interface then that is also an option. I'll publish it in a separate thread.
