Hoymiles has introduced the first plug-in solar microinverter in the U.S. designed to meet the new UL 3700 safety standard. Eight states currently have legislation enabling plug-in solar panels in the U.S., with more to follow. And now, there’s a legal and more affordable way to get some solar power flowing through an apartment or rental home. The Hoymiles HiFlow Pro is the first solar microinverter in the United States designed to meet UL 3700, North America’s new safety standard for plug-in solar panels, which are sometimes called balcony solar panels. Eight states—Colorado, Connecticut, Maryland, Maine, New Hampshire, Utah, Vermont, and Virginia—have legislation allowing the use of plug-in solar panels, but over two dozen have introduced legislation.
