    Posted By: WillInAberdeenRequirements are in G98.

    You mean para 10.1.10? I confess I'm still confused because elsewhere it says that systems with a single connection that use multiple inverters are to be considered as a single microgenerator. So I'm not clear whether 10.1.10 applies or not.

    It's all angels on a pin stuff though, since G98 is too new and doesn't apply to my installation.

    Another confusing aspect is that current Enphase products are different to what I have installed and can do all the things you suggest. I don't know what mine do!

    Quote jms452 "Hi All,

    Next step in transferring deemed FiT export to metered fit export.

    Octopus require confirmation that the DNO has been fully notified by the installer - This is what I received from the DNO (uk power networks):

    'We have checked our records and cannot find any reference to your property address. It is possible that the installer did not notify us at the time of installation. This installation should have been notified to UK Power Networks using the EREC G59 form as the capacity is above 3.68kW, whereas if these panels were installed today, the EREC G99 form would be required. Therefore an application cannot be made using either the older G59 form (now obsolete) or G99 forms.

    Given that your PV Installation has been connected to our network for over 8 years, UK Power Networks are agreeable to it remaining connected to our network but cannot provide retrospective approval.'

    The the thing I'm confused by is that while we have 4kWp panels our inverter is 3.6kWp so I'm not convinced the DNO is correct. What is the capacity of a PV installation the total rating of the panels or the rating of the inverter (i.e. the maximum the system can ever provide to the grid)?"



    I had exactly the same issue, there was no record of our notification, I contacted the installer who gave me a copy of the original notification and I sent that to the DNO who then confirmed receipt. I was advised that early on they didn't always keep copies of the notifications. Below 3.6kWp the DNO only has to be notified above that they must preapprove the installation.

    thanks Nigel

    It looks like octopus have accepted the uk power networks agreement (so far anyway).

    I'll see what the installer says just in case it's easy to sort.

    While waiting for an export meter just looked up the outgoing agile price (when it's not windy) compared to the 5.5p flat rate.
