I understand the OP wasn't in PR....I brought that up only to let you know that things work a bit differently here. Our version of 'modern' might have been outdated 25 years ago in the states.
That was a good explanation of the 'backfeeding the gen and why you can't do it' topic. Thanks for that. I was wondering why someone would even think about doing such a thing? Spinning the motor backwards sounds like something a bunch of 8th graders would try to do to one of their dad's generators just to see what happens! More likely you'd fry something in the gen electronics since it isn't expecting input at the outputs.
I watch with great curiosity the operation of the Tesla system and what it seems to be doing, since there's no grid to unload the excess juice to (in my case) once the PW is charged then it just throttles down the panels with a Hz shift up to where it just equals the demand from the house, if there's sun. If not much sun, it blends the PW output with the PV output to supply the house, switching instantly to 'top off' the PW when there's a burst of sunlight. Wash, rinse, repeat until sundown. Pretty clever and it works silently. We like that part a lot, especially after living on our gen for 4 months after hurricane María 3 years ago. Thanks for your input - you always shed some light on the topic.
