My ticket to Eco Build arrived today complete with a brochure with a picture of an Immersun.

Does anyone have any up to date information on the flicker problem? Has it been fixed with software revision?

I thought I might visit their stand and tweak their tails but before doing so, it would be useful to know the latest position.

I need to follow it up again with them.

To be clear though, this is unlikely to be a problem in the majority of cases, only in situations with particularly high grid impedance.

Right. Stupid question time:

The "flicker" issue is lights "flickering" when the immersun is dumping power.

This happens in the DAYTIME when the sun is shining brightly.

So here's the stupid question: WTF are your lights doing turned on, on a bright sunny day?

Or an understairs cupboard. Or the back of a garage. Or on a sewing machine for those with older eyes, or similarly reading a book. That's a few WTFs I have in my house.
Haven't yet installed my homebrew dump yet, so don't yet know if they will be issues. But part of the software has anti flicker capabilities for me to test.

I believe the mk2 ImmerSUN might also have a wireless sensor facility.

The famous Mk2 homebrew from another website will soon have an RF option too - no need for a wire between the fuseboard and the immersion (or other load).

Give it a couple of months...

I have been closely reading that other site, but my code is my own, and has far easier goals concerning accuracy to the last few watts.

Eco build likely to be the launch? The Wattson controller seems to offer wireless.
