United States — Ekhbary News Agency
Hoymiles recently launched its HiFlow Pro microinverter, introducing the first UL 3700-compliant plug-in solar device to the U.S. market. This innovation makes alternative energy more accessible for apartment dwellers and renters, allowing solar power to be drawn directly through standard household outlets. Several states have already enacted legislation permitting this "balcony solar" technology, with others considering similar measures.
New Safety Standard Bolsters Plug-in Solar Adoption
The microinverter's compliance with UL 3700 is a critical milestone. Adopted in December 2025, this national safety standard addresses a key concern: the risk of electricity flowing back into the grid during power outages, which could endanger utility crews. UL 3700 standardizes features to prevent accidental overloads and other safety hazards, effectively paving the way for wider acceptance of these small-scale photovoltaic systems. For what it's worth, this federal standard provides a necessary framework.

Expanding Solar Access Beyond Rooftop Installations
While plug-in solar panels may not power an entire home, they significantly reduce reliance on existing electrical grids without requiring extensive rooftop installations. This development expands the consumer base for solar energy, offering a practical solution for individuals in apartments or rental properties who previously lacked options for adopting renewable power. It represents a tangible step towards democratizing solar energy.
