Watch the digits! Yes even in Smart meters, the Disk WILL go backwards, but the count will always go up. Even in Mechanical meters for the last 30 years, there is differential gear that will only push the count up no matter which way the disk goes.
I also did not take the time to watch the digits... and I paid for the kWh going backwards AND forwards. When my array was inspected tested and approved by the utility they scheduled the installation of a net meter three weeks away. So I tested it myself and noticed that the disk would go backwards when I was producing and so I figured I'd flipp the switch on till the meter came. About when the meter came, I got my electric bill and instead of a near zero bill, my routine $200 february monthly electric bill DOUBLED to $400 because the meter added both directions to kWh (and did not subtract during production like a NET meter does). I paid the bill and ate my hat. In the spring and fall and no one is home during the day, when only the refrigerator is running, it only runs half the time as it cycles on and off. And when off, the sum of all the phantom loads of my house is only about 200W or so (one solar panel). So when the 8 kW of solar panels (40 of them) are producing the meter is running backwards faster than I have ever seen it forward. So there simply is no way to play grid-tie of any value unless you have a net meter. Just get one and you are good for life. Then you can plug any source of energy into any outlet and back feed all you want without worry. Even air conditioners and heaters cycle on and off. My conclusion is that the most solar panels you can grid tie witout a net meter is only about TWO. Otherwise they will overproduce when no one is home when thigns have cycled off and you will just be paying the uti8lity instead of getting the advantage.
