Don't forget you need an export MPAN somewhere in that list of steps.

That was meant to be implicit in Step 3, and the reason why I said it might take some time; because people comment here that getting the export MPAN can take some time.

I prefer to be explicit about things. Oo-er. 

That way people can read up about MPANs as well as everything else.

However, the best solution would probably be to give up the fit export payments in favour of SEG export payments.

(Leaving fit generation payments in place, subject to no changes to the fit system or changes that are likely to be approved and pro-rated payments etc etc).


It's likely that more money could be earned that way. Obviously do your own calculations, but there are better tariffs when you have SEG and potentially exporting more too (unless the plan is to use and store as near to 100% of the solar as possible). 

I think that is a good response and I agree possibly the best move.

My earlier post really just thrown out there to input another idea!

Reed you are right that a separate system technically could be switched , it is just a similar situation to a switched backup system but with different ( or manual ) control logic.

I would disagree that it would  be a money wasting excercise. That really depends upon the export quantity. 

If exporting everything ( or a significant amount) then why not get paid for it and not waste that opportunity.  It could then be MWE as you say. 

However if you hardly export anything ( the holy grail if on FIT that many of us have aspired to ) I.e. use virtually  all solar generation oneself from the additional system the  then nothing is lost. 

That is except for the one off switching cost that really would be essential for when the sun generates insufficient and the batts are empty.

It would need good calculation and predictions of own consumption  s generation  taking seasonality into account. Most users would not use all the generation from the size the OP is hoping for.

Still a separate system with SEG  for the whole is much easier, less complex and, if instead, just combined with the best import export tarrifs with battery time shifting etc., very attractive both financially  and green.

I think you, Reed and Pete, are very much on the right track for the OP.
