The last item in the link I provided requires:
"All renewable energy systems that do not utilize a U.L. 1741 listed inverter to feed power to FPL require a manual, visual load break disconnect switch"
The UL 1741 specification describes inverters that do precisely that switching function (https://www.homepower.com/articles/solar-electricity/equipment-products/ask-experts-grid-tied-inverter-approval https://www.homepower.com/articles/solar-electricity/equipme...)
So basically, "You have to install a safe system that won't fry our workers when they're trying to restore power."
I support that.
- ortusdux 9y agoMy generator backup system has this. The generator is fed into the box and routed through a breaker. This breaker will only switch on if the mains is off. In addition to safety, it just make sense to not dump your generator's energy into the grid.
