    Anytime know of a company supply and installing this for a reasonable price. I have the pv system installed since yesterday but my installer was looking for extortionate payments for it. Cheers

    How much is extortionate?

    The unit itself is 400 sterling then you have to buy ct clamps etc

    Get a used immersun, that's the unit they copied but the immersun had more features.

    That's pretty extortionate alright.


    Truth be hold, they look simple enough to install. You're essentially just connecting the immersion(s) to the output and then wiring the input up to the immersion power supply. I imagine any qualified electrician can do this in about 10 mins.


    What can make it tricky can be how you're controlling the immersion originally. If you're controlling it with a typical switch or mechanical timer, then the eddi basically replaces this as far as I can tell


    If you have a heat pump for example, this makes things a bit more complex as typically the heat pump will want to control the immersion as well. That'll require you to wire in the heat pump to the e-sense input of the eddi

    Can confirm it’s something on those lines.
    I’m not an electrician so forgive me if my wording is not perfect.

    I have the eddi in the hall beside my fuse board.
    It’s clamped using CT clamps and it detects when the PV array is sending power back to the grid. It reverses that and sends it to the immersion circuit.

    The old switch I had in the hot press upstairs to turn the immersion on/off is now gone as the eddi controls it.

    I can manually boost the immersion through the eddi unit though.

    Do you mind if I ask how much use you get out of the Eddi? Do you have a Zappi as well to charge an EV?


    I'm considering getting PV with batteries next year hopefully, and will be getting a Zappi for sure to charge my EV. I'm considering getting an Eddi as well for when there's a lot of excess solar and I'm not at home to charge the car
