Good day.
A grid-tied solar inverter senses the electric utility presence, its voltage and frequency in order to work and inject energy back into the grid... I think.
It shuts-off when the utility mains has a problem or ceases working.
If entirely disconnected from the grid, a grid-tied inverter is fed by an oscillator faking the mains; would it be tricked to operate and supply power as an standalone off-grid inverter to a non-grid load ?
Or,
If a small 1:1 transformer powered by a working mains provides a voltage and frequency just to trick the inverter the mains is normally present; would the grid tied inverter work normally providing energy to a not-grid connected load ?
Does an off-grid inverter uses some internal oscillator to make 50 or 60Hz and regulate the (240VAC) outputted ?
