De (heel) oude electriciteitsmeters draaiden
in de regel meestal terug, behalve bepaalde types die het mechanisch beletten of op een andere analoge manier (blijkbaar vooral na 1995 ingevoerd in bepaalde landen, die er vroeg bij waren met PV). Ook met de '70-'80-meters kon men pech hebben of geluk...

#4 Re: Meter running backwards
Actually, my old Analog/mechanical meter (decades old) ran just fine backwards (and decremented the reading).
As the others have said--It all depends. They started placing one-way ratchets on older meters a decade or so ago when people started generating their own power...

... The old analog meters unwind just fine. It's the newer analog ones, 1995+ that have a one way gear in them.
#6 Re: Meter running backwards
My old meter was installed before I moved in, which was in 1982.
It definitely did not run the dials backwards. I watched and watched the disk spin backwards, but the kwH dial would not budge.
When I looked behind the facade and saw the gearing, I could then see why.
So...like all things, it's whether you are lucky or not!

Just one data point. Our house was built in 1974, and had the original meter when we first installed solar. It decremented just fine. Pacific Gas and Electric, California.
