Install a changeover switch it would allow you to power your intallation from supplier or PV but never allow both to be connected.
You might, others wouldn't. Presumably your public liabilty insurer would cover an amateur installation.
As a matter on interest, how would such an interlock work?
You can not conect a DIY system to the grid !!!!! It is dangerous to line workers & ileagal. (Heavy fine & disconection + posible prison if some one gets hurt )
Solar isn't viable without the FITs, end of.

An install like this isn't rocket science, I would get the info on what was necessary to comply with regulations and job done.
The interlock is a purpose designed relay device that isolates the invertor when it senses grid power failure.
I wouldn't intend to just lash this up, it would comply with all the necessary requirements.
There are many that would disagree with your comment on viability.
A self installed system wouldn't get FIT but would cost signicantly less so the saving on energy bills alone would provide pay back in much less time.
Also, I would remove it if or actually, when I move, so the benefit would be transferred. It's a given that energy prices will rise so the more they do the quicker it pays for itself. And as panel prices come down I could add to the capacity of the system.
Well it's either this or my Lister CS startomatic !

I know thats a more difficult aspect to assess as it depends on how long the batteries useful life is. I have access to some decommisioned UPS batteries though !! 250 AH !!

thats what i been thinking about with mineIf batteries are too expensive the excess would always be used to heat water. Chances are you'll always use it for something.
Not my figure or assessment, it its that of the Royal Institute of Chartered Surveyors.
78 years, great......
so they just stop working in 25 years on the dot do they....and a max life of 25 years ( with fairly severe degredation of teh panels in later years....)

you said itdo be sensible
