Hi all, I am aware that there have been several threads regarding using pv to power the immersion and how to control the turning on of the same when the system is producing sufficient surplus output.
I have had a 3.84kw system installed for several weeks now and like everyone else want to make use of as much of the generated power as possible.
I have almost no knowledge or background in electrics so it may be that my idea is not possible or the components that I require do not exist.
what I was proposing to do is to mount a small solar panel,say 50w or 80w on a seperate roof, but with the same orientation as the main system and use the output from this trigger what I assume would be a relay in the curcuit and hence turn on the immersion. If I could adjust or source this relay to trigger at 50% of the panels output then the main pv system would be producing about 2Kwh. Obviously this method does not take into account what power is being used by other electical equipment in the house.
Elsewhere on here members have sourced 1Kw elements so thst is not a problem but is such a relay available that is adjustable with regards to the current required to trigger it.
Thanks in advance.
