Could someone please cast your eyes over this schematic. Im trying to switch FIT providers and Octopus are asking for one. The original 3.68kW FIT array has been supplemented by a new 16.83kW solar array and a DC coupled battery. Obviously the FIT generation meter only measures the output from the FIT array. Have I made any stupid mistakes please 🙂

We had a nightmare trying to switch out FIT to Octopus and gave up.

I don't see anything obviously wrong. You got a good G99 though!

@etchedpixels Thanks, this is actually for a nursing home Im helping. I found Octopus fine when I did my house, and I now get paid in days compared to several weeks with OVO 🙂

The diagram looks fine to me. When I had my export approved by Octopus (after the DNO approved it), I may have provided something showing the consumer units, isolators, etc. They also asked me for an electrical certificate and/or Building control, I cannot remember all the details.

But I posted a bit about it here, hope that helps. At the time this raised a few concerns in the forum, but, in the end, I just made sure the electrician applied a few more safety and warning stickers, etc. I never lost any sleep over it, we are all able adults in our household..

@batpred Thanks. Im hoping the installer will provide one soon, but if not I might try my luck with this one and see what happens. 🙂
