Net Metering Mystery Solved

Here's what happens when you generate enough electricity to run your electric meter backwards to zero. It doesn't stop at zero, it resets to the meaningless number: 99999. No doubt that's the highest number the meter can display.

Now for more fun... if I use enough electricity in the future (after using the credits I've racked up) will I get another chance to see the meter read zero?

I didn't get to see it switch from zero to 999999...maybe I can catch it as it changes from 999999 to zero...?
