I had a 4kw system fitted last November with a Mastervolt 5500 inverter. As I understood it, all the electricity produced by the system is first used by my house with the rest not used being exported back to the grid. I understand that if my house is using 1kw and my system is producing 2kw then I will be exporting 1kw back to the grid and not drawing anything from my energy supplier. Conversely, if my house is using 2kw and my system is producing 1kw, then I would see a 1kw draw from my energy supplier.
My problem is this. If I understand the above correctly, then why does my energy fit monitor which monitors the electricity coming into the house from the national grid never show 0, i.e. even when I'm generating 2kw from my system, the incoming meter shows me still drawing generally about 800watts with most things off in the house? Is it that the (e.on) energy monitor is not that reliable or is something amiss? Before the system was fitted, my house would draw about 500w when at "idle", now I'm drawing generally a minumum of 800w according to the incoming meter.
I have asked the solar company if this is correct and they say yes, that ALL my electrcity is exported back to the grid and the energy company know how much I am using - all the research I did prior to taking the plunge on solar suggested different. Finally, does the energy meter that monitors the solar draw electricity from the mains supply?
Thanks in advance for you help
