The claim still stands: the Quad's dual-mode edition can generate its own AC waveform and carry a
critical load directly from solar during an outage, no battery required, while a standard grid-following
inverter has to disconnect entirely on loss of grid. Full wording and citations at /applications/towers/.
Grid-forming vs. anti-islanding
Cut the grid. One goes dark. One doesn't.
Same sun, same moment — a standard inverter has to disconnect completely, by design. The Quad's
dual-mode edition keeps generating its own AC straight off the panels.
The claim, from /applications/towers/, with its own citations there: "The mechanism behind that
claim, per Jio's own installer material for the tower-relevant product, is grid-forming operation rather
than simple anti-islanding: the inverter can generate the AC waveform itself and carry a critical load
directly from solar during an outage. A battery is not a precondition for that, the same material
describes an off-grid mode running a critical load from solar alone, with no battery in the loop."
Precision this piece holds onto. The off-grid output is the dual-mode edition's datasheet row
specifically — the grid-tied edition carries no off-grid section. And the standard inverter here isn't a
strawman: anti-islanding is a real, required safety behavior (it's in the Quad's own certifications too
— UL1741 SA, IEEE1547) so a de-energized line can't be re-energized under a lineworker. The difference
drawn here is that the dual-mode edition can also do more than that, not that the standard behavior is
wrong.
What's drawn, not measured. The waveform traces are illustrative sine curves, not oscilloscope
data — nobody published one for us to trace.
