if you have solar pv and want to use unused power that would be exported, to heat your hotwater or heater ect.
but dont want to use imported leccy when you are using more than you are producing ie.
say you are exporting 1.5kw- 4kw and want to use it say running a heater when you are out
light switch or current switch will turn on your heater but if you turn on say a kettle you will now be using imported leccy (not good)
this system turns off the heater if you are using more leccy than your production so if its a bright day your heater turns on untill a cloud comes over or you turn on a kettle or tumble dryer
then when kettle has boiled the heater turns back on again
you can build the device for around £15 if you are good at diy
if you want to know more about it message me and ill try and explain better
update:
if you have your leccy meter a long way from your heater and if you dont want to run a wire to the controller this can be done with a transmitter and reciever for an extra £12ish

Hi, just wondering why you don't want this discussed publicly. There will be a lot of interest in something you can build for that price, and you can rest assured the community here will find ways round problems, or even come up with ideas to make the thing easier or cheaper or more reliable..
You can reply by PM if you prefer.0 -
hi kernel
if you take a look at my past posts i dont mind discussed publicly
but there a few on here that like to think they are always right
and dont like other people having some thing they cannot have.
if i can help anyone for free i will,
this device is not for everyone only people who have solar pv and are good at diy its not easy to explain thats why i sayed message me so i can tell them where to buy the parts and how to build it
if it can save you money for £15 ish then if they are intrested then ask and ill do my best to help
ive only put it on here after recieving a pm from a member asking me about it and he called me today after buying the parts from a local shop and said i should tell everyone and share the info.
but like i say its not for everyone.
i'll share any money saving ideas i have ive even got a system in place to save £500 of my water bill that has been running now for last 4 years0 -
