More Solar PV Immersion Questions...

Just thought I'd post some progress on here. Have searched the forums and can't see any mention of these products so some members might not be aware of them.

Many people have been looking to divert the excess power from their solar PV arrays to the immersion heater in their homes to save on current costs. There are plenty of "home made" ideas out there but by the end of the month there will be two versions made by companies and sold commercially.

The first of these is called Immersun, you can see some general information here.

This is due to cost around £500-£600 fully installed and available through installers, who you can find on their website. Just put your postcode in and it will recommend the nearest.

The second option is available toward the end of the month and will be advertised on the website below.

At present the mark II version is the latest model but they are working on a mark III version which will have intelligence and divert all excess generated electricity to the immersion. The price of this should come under the £300 mark but you'd need to find your own installer, by the sound of it.

Both have phase sensitive sensors, so you only need one clip on sensor to monitor.
Both are proportional so if you're only generating an excess of 200w then that's what goes to the immersion.
Both utilise the existing immersion element so no need to change.
Both will have a timer so if the water doesn't hit the right temparature you can can it a boost by importing electricity.

The more expensive one has a LCD screen which tells you how many kWh's you've saved and could be used on bigger set ups including a commercial setting.

Hope that helps!

It might be a little more helpful if instead of posting the same thing in multiple threads, you just made one posting (to which people can reply) and then cross-post in other relevant threads to direct people to your new posting. That way the pro's and con's can be discussed in one thread instead of 4!
