[QUOTE="binky, post: 388473, member: 490"] no his owl is wired backwards - we had this on one of my early jobs, when the customer switched his hoover on the 'output fell' - PV is outputting but been seen by the clamps as flowing in rather than out. The most a PV system will add to the leccy bill is about 10watts overnight on standby. Modern didgital meters do not register the output to the grid, unless its an export meter. The installer should have supplied a remote display so the customer can see what is going on with his system, and utilise the energy generated effectively. I suspect if his bills are up, then it's becuase he thinks he's getting all his electric from the panels and has since switched on every appliance like it generated 4kW all day long, when the reality is that is PEAKS at 4 kW somewhere between 10am and 3pm it is possible that his meter is faulty, but Owls and variuos other devices like that use current clamps on the meter tails, which are cheap, and prone to misreading EMF from surrounding electrics [/QUOTE]
