Price does not look to bad, developer does knows his onions not HAH related but i know a lot of you "do" this.
the intresting bit for me is the clamp goes "one way round" and can detect if feeding or drawing from grid.

i-GEN Solar Boiler. Heat your
i-GEN Solar Boiler. Heat your DHW with excess PV..... that's what it might become!
I'm at the beta test stage of my own implementation of this type of kit - I've got 15 PCB's left waiting to be populated, so if you're a dab hand with a soldering gun you can have one to test for the price of the parts (about £175 - £250 depending on what you want)... send me a PM and I'll reply with more details....
Also, this system interfaces directly with a CC EnviR and gives 3 Wattage readings (Usage, Generation, Feed to Boiler) which you can see in near to real-time on your HAHub and post onto Pachube.... take a look at http://cosm.com/feeds/34982 on ID's 15, 2 and 18.
Here's some teaser photos....

Yup...and nope!The kit
Yup...and nope!
The kit includes the case and all the bits including matched CT coils..... but you're right, the build costs are what moves the price up into the 'commercially available' price range.... having seen the build quality of the others I think we're above par! And if you build it yourself - no additional cost!!!
I've been told CE approval isn't required on 5V systems - eg wallwarts and low power stuff! - but we can pass part 15 on application and we're opto-isolated from the mains side, but it'd still require a full-fat electrician to install....
Also, some tweaks and enhacements and the availability of 'cheaper' bits might bring the parts cost down.. If I was buying in large qtys that'd definitely be the case!
I'll let you know how it pans out.... but the offer still stands - if you want to roll your own, I can provide the bits....

electrician?
Its a <3kw heater in the tank, so long as you have a socket on your solar output then I suspect it could legally be plug in.
If you could find an immersion heater with a kettle plug you are away.

Awesome-ness.Now that I'm
Awesome-ness.
Now that I'm relocated back down under Solar installation are everywhere! Its like a blight on peoples rooftop there is just so many installations, not suprising that we average 300 days of sunhine a year. Even winter here is blue skies and sunshine. After being in the UK for so long its seem so wrong to see so much sun?!
I'm itching to find a house that either already has a setup or will be installing my own VERY soon and I know just the thing to monitor it :)

Cool did you have to change
Cool did you have to change your immersion down to a lower wattage? How much did it cost for the unit and installation?
Using an Arduino to phase control 220V AC mains power.

basically an adjustable solar energy dump.
