I have no idea what that figure is e.g. instant, hourly, daily etc. but not downloadable for scrutiny.

Has anyone used this facility?
Has anyone tried independently ( of any SEG scheme ), datalogging PV export. I'm trying to get a better picture of my PV export, not just the 50% deemed that is my FIT contract.]]> http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=17882&Focus=302195#Comment_302195 http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=17882&Focus=302195#Comment_302195 Wed, 28 Jun 2023 17:47:48 +0100 revor if i am correct if you have a smart meter then you should be able to get an export payment as well as your FIT. Your FIT is for generation and export for what you actually sent. There are those on this forum I think get this.]]> http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=17882&Focus=302197#Comment_302197 http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=17882&Focus=302197#Comment_302197 Wed, 28 Jun 2023 19:32:45 +0100 owlman http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=17882&Focus=302198#Comment_302198 http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=17882&Focus=302198#Comment_302198 Wed, 28 Jun 2023 19:55:12 +0100 revor Posted By: owlmanThanks revor, I think you can get PV generation and metered export, but I already receive the deemed 50% export. That's interesting regarding meter manufacturers to get meter access. Some sort of datalogging would be good too.

Do you have smets 1 or smets 2 Maybe you need a smets 2 for export payment.]]> http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=17882&Focus=302199#Comment_302199 http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=17882&Focus=302199#Comment_302199 Wed, 28 Jun 2023 20:16:07 +0100 owlman I wasn't intending to change the current FITs contract, simply to get a better understanding of my true export, vis-à-vis Grid import, say for the next year or so.]]> http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=17882&Focus=302203#Comment_302203 http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=17882&Focus=302203#Comment_302203 Wed, 28 Jun 2023 22:07:43 +0100 djh Posted By: owlmanHas anyone tried independently ( of any SEG scheme ), datalogging PV export. I'm trying to get a better picture of my PV export, not just the 50% deemed that is my FIT contract.I measure my generation at my generation meter and my consumption/export at my main meter. In both cases I use both an optical reader stuck to the meter and a CT on the cable. I feed both lots into my emoncms system that can draw pretty graphs or export CSV etc. I also record the meter readings by hand at least monthly (daily for generation) for true accuracy.

If/when I get a smart meter I expect I'll be able to get the export data directly. I'm currently thinking of switching to the Intelligent Octopus tariff which will require a smart meter.

edit: to add that my FIT contract is currently with Good Energy but they've made a real pig's ear of my account at the moment so I'm thinking of moving it.]]> http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=17882&Focus=302205#Comment_302205 http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=17882&Focus=302205#Comment_302205 Thu, 29 Jun 2023 09:35:13 +0100 Mikel
What I found to particularly useful is the power requirement display (kW) at any one time. You can also get the hourly grid import data. If you have a PV datalogger that shows current power generation, you can use all of this to optimise using very devices, washing machine, oven, dishwasher.

I have found that it is very difficult to get a zero grid import during the day as my PV doesn’t generate enough power.]]> http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=17882&Focus=302216#Comment_302216 http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=17882&Focus=302216#Comment_302216 Fri, 30 Jun 2023 12:56:03 +0100 owlman
