Hoymiles has officially launched the HiFlow Pro, the first microinverter in the US to earn UL 3700 certification. This safety standard is the missing link for plug-in balcony solar setups, which are gaining legal traction across various states.

WHY THIS MATTERSThis tech lowers the barrier to entry for renters who want to offset their electricity bills without permanent modifications to their unit. If your state laws are evolving to allow balcony solar, this hardware is the bridge to actually getting it done safely and legally.
