Over voltage

[JohnD]

If grid voltage was too high, I think I'd like to see anything generated from the solar diverted to heating water or something.

Battery storage would be ideal.

Indeed - so would I.

However, I thought that grid-tied inverters shut down in the event of an 'overvoltage' of the grid supply - I would imagine primarily due to export problems?

Yes, mine does, but a few resistive loads pull down the in-house voltage a bit.

The iboost+ sounds a good idea, but the immersion heater is not deep enough in the tank, so it does not use as much as I would like, and if I ever do get paid for export, the figure for export is higher than the figure for buying off-peak, so not really worth doing.

..."Household" Solar Panels (EXPORTING energy) tend to push-up the voltage in the "local area".
This must be so, since the only way that such panels can "feed" into the (local) part of the "Grid" is to produce a higher voltage - to drive the current in - thus taking part of the "load" from the local "Grid" transformer...

In essence yes within reason but not quite correct, Kirchoffs law just about starts creeping in here.
