We have just had a solar PV system installed - the worst time of the year for the UK
I am looking to monitor generated power and currently consumed power by use of Hall effect transducers. In the summer months I am expecting to be generating more power than I am using in the daytime and want to switch on the immersion heater and heat up my hot water when there is spare generating capacity. How can I do this with X10 controllers? Will it need to be controlled by a computer and software- based solution or is there an off-the-shelf controller which could be programmed to do it for me?
TIA
