Features & Benefits

420W of Solar Generation

Generate renewable electricity with two high-efficiency 210W flexible solar panels, providing 420 watts of total solar panel capacity.

The dual-panel configuration captures more sunlight than a single-panel setup while maintaining a compact footprint suitable for balconies, patios, and other space-conscious installations.

Ultra-Thin & Lightweight Flexible Panels

The panels feature a frameless, all-black design with an ultra-thin 3mm profile.

Weighing just 3.6kg (7.94 lbs) per panel, their lightweight construction offers greater installation flexibility compared to traditional rigid solar panels.

Smart Hoymiles Microinverter

The included Hoymiles HMS-420-1WM-LV HiFlow Pro microinverter converts the DC electricity generated by your solar panels into grid-compatible AC electricity.

With a rated output of 420VA, this advanced microinverter is designed for compact residential solar applications.

Plug & Play Installation

Designed around a simplified installation approach, the Hoymiles microinverter includes a plug-and-play AC cable for convenient connection to a compatible electrical outlet.

The compact system makes residential solar generation more accessible without requiring a traditional rooftop solar installation.

Smart Energy Monitoring

Built-in Wi-Fi and Bluetooth connectivity allow you to monitor your solar system's performance using the Hoymiles S-Miles Home app.

Track energy production and access system performance information directly from your smartphone without requiring an additional communication gateway.

Advanced Safety & Weather Protection

The Hoymiles HiFlow Pro microinverter features an outdoor-rated IP67 enclosure, integrated rapid shutdown, and galvanically isolated transformer technology.

Its fanless construction uses natural convection cooling for reliable operation across a wide range of environmental conditions.

Please Note

Actual solar energy production and electricity savings vary depending on sunlight exposure, geographic location, installation orientation, shading, and local electricity rates.

The Hoymiles HMS-420-1WM-LV is a 120V grid-connected microinverter. Installation and grid interconnection requirements vary by state, local utility, and authority having jurisdiction. Always verify applicable electrical codes, utility approval, permitting, and installation requirements before installing a grid-connected solar system.

Panel and microinverter compatibility, including the approved connection configuration, must be verified against manufacturer instructions before installation. This kit is intended for use with the two included 210W solar panels.
