## Small-Scale Solar Energy

Hoymiles' HiFlow Pro microinverter enables solar power usage through standard household outlets. This technology makes alternative energy more accessible, especially for renters.

## UL 3700 Standards

Adopted in December 2025, UL 3700 is North America's first safety standard for plug-in photovoltaic energy systems. It ensures the safe use of small-scale solar panels.

## Safety Measures

UL 3700 prevents electricity from being drawn into the grid during outages, ensuring the safety of service crews. This is a critical measure to avoid accidents.

## Legal Regulations

Some US states have passed laws permitting this plug-in solar technology. Others are considering similar measures.

## Consumer Base

Federal standards expand access to solar energy, offering new opportunities for renters and apartment dwellers who cannot install rooftop systems.

## Step Towards the Future

Hoymiles' innovation paves the way for the widespread adoption of small-scale solar energy systems. This is a significant step towards sustainable energy transition.
