Inverters must be certified to UL 1741 (anti-islanding per IEEE 1547).
Passed both chambers unanimously and became the national blueprint — every later state bill references it.

Safety basics (everywhere)

Regardless of your state's law, use a kit with a UL 1741 (or UL 3700) certified microinverter, plug into a GFCI-protected outlet on a dedicated circuit, and don't exceed the circuit's rating. These are the same safety rules the new state laws are built around.
