Renters Can Now Plug Into Solar Power!
21 Jul
Summary
- New microinverter allows solar power through household outlets.
- New safety standard UL 3700 adopted for plug-in solar systems.
- Expands solar potential to renters and apartment dwellers.
A significant advancement in alternative energy accessibility has been made with the release of the HiFlow Pro microinverter. This device permits the use of solar power directly through typical household electrical outlets, making solar energy more attainable for renters and apartment residents.
This plug-in solar technology is gaining traction, with several U.S. states enacting laws and proposing measures to allow its adoption. The Hoymiles HiFlow Pro is particularly noteworthy as the first in the U.S. to comply with the newly established national safety standard, UL 3700.
Adopted in December 2025, UL 3700 is the inaugural North American safety standard for plug-in photovoltaic energy systems, also known as "balcony solar." A key concern addressed by this standard is the risk of power backfeeding into the grid during outages, which could endanger utility crews.
UL 3700 standardizes safety features to prevent accidental overloads and other potential hazards. While not capable of powering an entire residence, this plug-in solar solution offers a means to lessen dependence on the main electric grid.
The establishment of a federal standard for these compact solar setups broadens the market for solar energy, including individuals in rental properties or apartments who are unable to install traditional rooftop solar panels.
