Utility Power metering on 120v plug and play Solar
I am looking at adding a EcoFlow STREAM Microinverter to my house, this is a plug and play solar system you just plug it into a north American standard 110-120v outlet and you are done.
I live in Utah one of the only states where this it legal to install plug and play solar. However without the smart meter any power I back feed to the grid I will be charged as if I consumed that power, and to add a cherry on top my power company has paused deploying smart meters at the moment. For the moment I am on an indefinite wait list.
This leads me to my question. I have Single Phase power at my house. Line 1 (120v) and Line 2 (120v). (Both lines together gives me the 240v) Standard stuff in North America. Does anyone know how the power companies' meter handles power back feeding from Line 1 but drawing from Line 2?
For example if the Inverter is plugged into an outlet on Line 1 and is producing 1000 watts (back feeding to the grid). But I have a load on line 2 that is consuming 1000 watts what will the utility meter see? Will it see 1000 watts on Line 1 and 1000 watts on Line 2 and charge me 2000 watts of consumption or will it see 1000 watts going out and 1000 watts coming in and equal out to 0 watts?
I use about 1kw constantly give or take 100 watt. And my inverter max is 1200 watts. (I am only plugging in 3 395 watt panels, I doubt I will hit 1,200 watts very often or very long. it should basically equal out or be close enough it shouldn't really matter. However if I can only off set Line 1 power and not Line 2 I will be in trouble.
I called my power company's net metering support line but I think I explained myself so poorly, I ended up confusing the representative. But I got the feeling they wouldn't have known the answer anyways.
