Hoymiles launches first UL 3700-compliant plug-in solar microinverter in the US
Hoymiles has released the HiFlow Pro, the first UL 3700-compliant plug-in solar microinverter in the US. This product allows renters to utilize solar power via standard household outlets, promoting wider adoption of small-scale solar energy solutions.
Key points
- Hoymiles introduced the HiFlow Pro microinverter for US markets.
- It complies with UL 3700, the first national safety standard.
- Designed for use with plug-in photovoltaic systems.
- Expands solar access for renters and apartment dwellers.
Introduction of HiFlow Pro Microinverter
Hoymiles has launched the HiFlow Pro, marking the first UL 3700-compliant plug-in solar microinverter available in the United States. This innovation allows users to harness solar energy through standard household outlets, making solar power more accessible to a broader audience, particularly renters.
Adoption of UL 3700 Safety Standards
The UL 3700 standard, adopted in December 2025, is the first national safety guideline for plug-in photovoltaic energy systems, colloquially known as 'balcony solar.' This standard addresses critical safety concerns, such as preventing overloads during electrical outages when energy could inadvertently be sent into the grid, posing risks to repair crews.
Impact on Solar Energy Accessibility
The introduction of the HiFlow Pro microinverter signifies a shift towards more accessible solar energy solutions. While it cannot power an entire apartment, it provides an alternative for reducing dependency on the electric grid. This development is particularly beneficial for those unable to install traditional rooftop solar panels.
Legislative Support for Plug-In Solar Technology
Several states have approved laws to facilitate the use of this plug-in solar technology, with additional measures under consideration. This legal support could drive further interest and adoption of microinvereters like those from Hoymiles, encouraging a broader societal move towards renewable energy sources among renters.
