I only tested it myself for a few days but can't say I noticed any flicker or anything. Like I said a 1000W immersion element and a timer or indeed something smarter could be a good low cost compromise solution. Plenty of inverters and cheap monitoring systems with good reporting nowadays that could be used to switch a WiFi controller on once production or export reached a threshold.

All quite doable and with a higher reward than water heating, but even less practical than an immersion diverter as it would involve having to use my granny cable, not my normal dedicated and secured EVSE charger and of course having to plug the car in all the time. Meh. I'll just force myself to be patient and wait for a FIT. And build a big fook off battery

I am getting 2.86 for Sep so far. Note the numbers in my initial post were guesstimates reading off a chart. I got the actual numbers for this post.

It's a bit of a trial really as I'm fitting it on my garage roof where I do get a bit of shadow. I've paid the extra and gone for Optimisers, iBoost+ and Buddy so excess electricity can go to the Immersion heater. The 'Buddy' will tell the wife, who's at home most of the day, when we're exporting so she can go around the house turning all the lights on (oh, she does that already!). I'll get to the point. I'm quite hands on but would like to get a look around someone else's system for various pointers and tricks so I don't look at it for the next 20 years thinking how differently I wished I'd installed it. I'm Donegal Town based and would love to have a look at another install as locally as possible. Many thanks to all in anticipation. Bren.
