Eon incorrect solar inverter installed advice sought

If the system is expanded e.g. more panels, FIT generation can be paid on a proportion of the generation - e.g. if you doubled the kWp, FIT generation payments would be pay half a unit for every unit generated. 

So yes, you can add more panels,  But no, you can't get paid for the electricity they generate.  So as I think I understand your current situation, you should not have seen any increase in your FIT payments.

I'm sorry to be asking a stupid question but assume the smart meter you refer to isn't the one our energy supplier gave us 

No the smart meter I refer to IS the one your energy supplier gave you.  It should give you a reading of what electricity you have exported (since the meter was installed).  And if you apply to be paid for actual export it is changes in that reading that tell your provider what you have exported and how much to pay you.  My smart meter shows me, Date, Time, Import, Export in sequence but I believe on some meters you might have to press some buttons.

One or both of your inverters should measure the instantaneous power you are exporting and it can use those readings to give you a good estimate of what energy you have exported but this is not deemed to be accurate enough to get you any payment.  If you don't have an energy-supplier-smart-meter you can't get paid for actual export and you will lose out.

I think you can add a battery to an existing solar system without affecting the FIT.  But you cannot add more solar panels unless they are part of a completely separate system.  It sounds as if that is what you have done, although you don't make it completely clear.  

       

As pete explained, you can add more panels to an existing FiT system, you can also replace panels with more powerful ones.

I'm not entirely sure how this myth about not being able to amend a FiT system started, but I have tried to push back against it for a decade or so.

For more info you can review this thread.

It's not so much that you can't amend it but that it will be proportional and when I looked at that it wouldn't be worth it. We have replaced the inverter but that was a like for like change. Maybe it's also come from the declaration with every FIT meter reading that there have been no system changes.

Thanks for your responses, sorry for radio silence I've not been well.  

Well eon and installers after rnuch mucking about have finally fitted the correct Inverter. I've asked for a detailed line drawing to show how the battery and system works with the existing system (is it totally independent) so I can register this info with our fit supplier and make sure it's all above board.  Can you claim fits on original and seg on new system then?

One other minor thing the solar edge ap now shows both systems but since the engineer put the new inverter in the daily bar graphs have disappeared off the ap only since the install date.....is this something I should get in touch with solar edge directly about as it's an app problem or is it because of the new inverter which should be the installers/eon? (I have been in touch with the latter but seeing how slow they move I wonder if I should be going down the solar edge support route).

Not exactly.  Provided you can measure the generated energy from just your old system you can continue to claim the generation component of the FIT-scheme payment.

You can then either claim an SEG payment for all your exported electricity and forego the deemed export part of your FIT-scheme payment.

Or you can continue to claim your deemed export payment under the FIT-scheme and forego any payments for electricity exported by your new system.
