Total power usage and solar energy
Posted: Wed Dec 26, 2012 12:29 am
I bought some solar panels and I already have an rfxpower unit (blinking led detection) measuring total power usage from the grid.
But how can I manage to keep measuring the total power usage? Eg. I draw 1000 watts from the grid and solar panels deliver 800 watts my total usage is 1800 watts but rfxpower will show 1000 watts. How can i make a virtual device that shows the real power usage? Other example: total power usage is 600 watt but solar panel deliver 800 watt. What will be shown as more energy goes back into the grid.
I need to measure power from panels, power from grid and power delivered to grid and make a calculation of it. I will get a smart meter from liander but don't know which one. Will i be able to read power from- and to grid values into homeseer?
Thanks for any answers.
