I'm LongbridgeAI, I can summarize articles.Hoymiles has launched the HiFlow Pro, the first plug-in solar microinverter in the U.S. certified under the new UL 3700 safety standard. Designed for balcony or rental use, it connects to a 120-volt outlet, offering an affordable, non-permanent solar solution. Currently legal in eight states, the system features built-in safety safeguards and Bluetooth/Wi-Fi connectivity, with kits priced from $499 to $700.

- Eight states currently have legislation enabling plug-in solar panels in the U.S., with more to follow.
Solar panels are great, especially in areas where the sun shines all year round. However, not everybody lives in a house or can afford costly setups, but that’s where plug-in systems come into play. 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 certified to meet UL 3700, North America’s new safety standard for plug-in solar panels, which are sometimes called balcony solar panels.
The microinverter takes power from a mobile solar panel and funnels it directly into a regular household socket, minimizing grid usage and lowering energy bills. This approach, however, raises some safety concerns, but there shouldn’t be any, as long as UL 3700 is enforced. That’s there are built-in safeguards that automatically cut power when there’s a grid outage, to protect line workers. The microinverter also cuts power to the exposed pins on the end of the cable to avoid the risk of electrical shock.
Hoymiles claims the output voltage drops to less than 34V within 1 second after disconnection. Furthermore, the enclosure is NEMA Type 6 and IP67-rated, allowing dwellers to install it outside in temperatures ranging from -40°F (-40°C) to 149°F (65°C).
All this being said, this is not the type of system that will keep the lights on all the time, no matter the weather. One microinverter is rated for 360 watts, with a 95.5% dynamic efficiency and a 99.8% static efficiency.

Up to four microinverters can be used in parallel, each plugged into a separate outlet, for a maximum input of 1,200W. The company says the units can be set up in just one minute, thanks to Bluetooth and Wi-Fi connectivity, and that the total annual energy production can go as high as 2,403 kilowatt-hours in ideal conditions, with a two-year return on investment.
Right now, the price for a 180W kit that includes one solar panel retails for $499, while the 360W kit goes for $700.
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.
This type of system is hugely popular in Europe, especially in Germany, and that trend is now moving toward the U.S., enabling more people to enjoy solar power wherever they live. What’s more, as balcony solar doesn’t require a permanent installation, the owner can just pack up the equipment and take it with them when they move.
