Journalistic ignorance of solar

Articles like this are annoying.  I know where the reporter got the initial idea (the requirement for a disconnect on Florida grid tie systems) but then he leapt to some completely unsupported conclusions. 

================
More egregious, FPL mandates that if the power goes out, your solar-power system must power down along with the rest of the grid, robbing potentially needy people of power during major outages.

"Renewable generator systems connected to the grid without batteries are not a standby power source during an FPL outage," the company's solar-connection rules state. "The system must shut down when FPL's grid shuts down in order to prevent dangerous back feed on FPL's grid. This is required to protect FPL employees who may be working on the grid."

Astoundingly, state rules also mandate that solar customers include a switch that cleanly disconnects their panels from FPL's system while keeping the rest of a home's power lines connected. But during a disaster like the aftermath of Hurricane Irma, FPL customers aren't allowed to simply flip that switch and keep their panels going.

    If they were formally educated on the subject like I was then they wouldn't be working as a reporter.

    Which begs the question, how many of you have tried to force a grid-tied inverter to fire up without the grid?

    I suspect it depends a lot on the inverter.
    Off-grid.

    And depends on what the psudo grid is.
