Fooling a grid-tie inverter to provide power without grid.
off grid inverter..no demand no output grid tie inverter.generated as much power as available and assumes that the grid can use it all Grid tie..grid tie inverters must monitor the grid for 5 minutes and watch voltage and frequency. EDIT: and not output any power until the 5 minute clock is up. END EDIT.
Is there such thing as a "selfish" (non backfeeding) grid-tie inverter?
Yes, I know grid-tie inverters won''t backfeed when the grid goes down completely, but I want to avoid EVER sending power to the grid, even if the grid is up and working and I''m making more power than I need. Instead of going back to the grid, excess power generation should be automatically shed or otherwise somehow ''wasted''.
