How accurate will a mains "house" type meter be whilst running on a pure sine inverter?
(and a genny come to that)

If its accurate our power consumption is quite a bit LESS than I have calculated it to be.

Hi Justme,

I'm no electrician but I have three proper mains ones in my system, one for the house, one for the genny and one for a chalet that I let. The one that meters the chalet also has a cheap digital one in the line and it reads the same as the 'pukka' one (less a watt or so for driving the wheel) so it seems unlikely that they're both inaccurate to the same degree. Well it does to a numpty like me :-)

Cheers, Paul
