I do have a zero report inverter. I also have a separate circuit panel for my main and my secondary. Both panels are powered when the grid is up, even when all of my power is coming from solar. But when the grid is down my secondary panel gets no power because it’s tied directly to the grid. My inverter won’t power those circuits (to protect the line workers) unless I flip a manual switch to connect the two panels, flip another switch to disconnect from the grid, and put my inverter in full off grid mode.
Thank you, I’m looking at installing a small zero-net system.
I installed wattmeters on L1 and L2 incoming electric mains to track my usage, the average is 20.1 kW total per 24 hr
The daylight average is less than 1kW per hour even in the heating season.
My wife and I installed heated floors in our 100-year-old house, the gas boiler and 2 small pumps use less than 300 Watts but will run 24/7 when the temperature is less than 10 degrees.
Thinking, I installed the AC around 1990!!! Still runs well!
Because we have some large beautiful trees, we seldom use the AC.
When we do turn the AC on, the meter spins so fast, you can use it for a meat slicer.
So far the numbers point to a small system of about 1kW, and if needed I can add more panels.
