- I'm allowed to connect it to the grid without requiring
authorisation, as long as the equipment conforms to grid connection
standard 'G83/1' and I inform my electricity supplier

I wouldn`t like to say on that one, but I thought it was something
like G58 protection. Its not the easiest thing to google for though -
i`ve tried !

Specialist metering may well be required, and speaking as someone
within the industry, I can tell you for certain that Scottish Power's
metering dept. have not come across this type of installation yet, and
have no metering capable of handling the export.

This has been the case for at least ~18 months or so from when I first
heard about the Whispergen (and the other one, for which I forget its
name), before any had been installed in the UK.

I believe United Utilities and one site in the Newcastle area may now
have had these installed in an estate as a trial, but it was with
specialist metering IIRC.
