Solar Immersion Controller

[EWP]

Hi Guys,

Lots of rummors around do these things atcually work.

Well here is a little U-Tube video i made ealier of a SOLiC 200 in action in my home today.

SOLiC 200 stops Electricity Meter Disk dead. - YouTube

I might be the company making the SOLiC 200, but i think a picture (in this case a Video) speaks 1000 words!

Enjoy watching an old style electric meter disk stopped dead in its tracks. :laugh3:

Watched it and it looks great, thought you might be the supplier though.

Are you aware that if your meter is running backwards though that you have a legal obligation to contact your energy provider?

 

[EWP]

Yes I am the manufacturer with my partner.

What you seeing is an R&D set up with the SOLiC 200.

And yes i have told the Electric company about the backward meter, so i guess they will change it in due course.

Thank you for the comment in the meantime.

So are these things only for immersions or could they be used for other loads? I have a combi boiler so don't have an immersion and at the moment hardly use any if the power I produce, so, I was looking for a device which could monitor and then control something like electric heating or an air source heat pump. Will be keeping an eye on this post

Hi Steve, no pics yet?

From what i understand here that video showed an export of 1600W? Now if you put that into something like an immersion that was say 3KW it would get it warm, but not hot though, however a Heatpump needs a specific amount of power for it to work at all.

Think of it as a 12v light, put 2v in and it would be very dim, put 6v in and it would be brighter, put in the full 12v and there you go you can see with it now.
I know this should be watts not volts, but can you see the correlation?

There are not many items you can operate that will work on an amount of power that is less than they need, and because PV can have such a variable export what can you choose?

This is why people tend to use an immersion heater, you could use an oil filled heater too maybe, but when you are exporting the most you will not need the heater on.

I hope this helps.

Spot on Earthstore. Although in our experience even with very small loads the water gets hot in the Immersion tank, just takes a lot longer.

Remember every degree you raise it saves you heating it another way.

1600 was the generation amount not the export, you have to take the house existing electrical load to take off first, hence the sensor sits on the mains cable and measures when electricity is being exported.

Soz Kevin, have been flat out changing my MG engine ( never a dull moment! ). Have taken a few pics, will make some time and get them off to you.
How you've explained it makes sense now

 

[Earthstore]

Is that the B series 1800? The one that started life as a 1500cc in the 1950's maybe in the Austin A 50?

 

[Steve_rutland]

No it's the slightly more modern ( 2004 ) MG TF. Is the old K series engine though. Lil project I picked up last October

 

[Earthstore]

Superceded the A series, but the Head gasket fails because of inherent design fault.
Sorry to digress chaps.

watts is watts though, and it makes no odds whether you input 3kWh in a single hour or 2 hours, or 10 hours it will still provide the same level of heating capacity to the water in the tank (other than the thermal losses from the tank etc)

will it charge my new electric car?

 

[EWP]

Should do yes, as it just provides power to any circuit, when available.

What is the best solar immersion controller out in the market does anyone know?????
i been reading about ABSwitch solar utiliser SU001 and the IMMERSUN but dont know which ones are the best to monitor the extra electricity your PV generates will be used in the house for heating your hot water and not using electricity off the grid.

Can anyone tell me please about this??????

 

[Dee]

Also is there an immersion controller that could monitor the electricity produce from the 4kw pv system to the house i.e how much is being used in the house together with monitoring how much is being used from the grid to your house.


Some one please tell me thank you.
