Hoymiles HiFlow Pro LV 360W Plug-In Microinverter

1-in-1 120V Microinverter with Built-In Wi-Fi & Bluetooth | HMS-360-1WM-LV

Simple plug-in solar with built-in monitoring. The Hoymiles HMS-360-1WM-LV is a 360VA, 1-in-1 plug-in microinverter designed for small residential solar installations. It combines a single PV input and MPPT with 120V nominal AC output, built-in Wi-Fi and Bluetooth, and S-Miles Home app connectivity without requiring an additional DTU.

The Hoymiles HiFlow Pro LV HMS-360-1WM-LV provides a compact way to convert power from a single compatible solar module into 120V AC. Hoymiles designed the HiFlow Pro LV series for residential applications including balconies, terraces and gardens, with a plug-and-play architecture intended to simplify system installation.

Built-in 2.4 GHz Wi-Fi and Bluetooth allow local and remote commissioning and direct communication without a separate DTU. The microinverter works with the S-Miles Home app for system monitoring and smart home solar system customization.

Designed for One Solar Panel

The HMS-360-1WM-LV features one independent MPPT and one PV input, making it a straightforward microinverter option for single-panel plug-in solar installations.

Hoymiles specifies a commonly used solar module power range of 280W to 470W+ for the HMS-360-1WM-LV. The inverter supports a maximum DC input voltage of 60V, a 16V to 60V MPPT voltage range and a maximum input current of 14A.

Its 360VA rated AC output makes it particularly suited to compact solar installations where a full-size multi-panel microinverter is unnecessary.

Built-In Wi-Fi & Bluetooth

Unlike systems that require a separate communications gateway or DTU, the HiFlow Pro LV incorporates Wi-Fi and Bluetooth directly into the microinverter.

This enables direct communication and commissioning while providing access through the S-Miles Home app. Hoymiles specifically designed this functionality to simplify setup and allow users to monitor and customize their smart home solar system.

Plug-In AC Connection

The HMS-360-1WM-LV is part of Hoymiles' HiFlow Pro LV plug-in microinverter family. The manufacturer specifies a Type B plug  (standard North American 3-prong grounded plug used with common 120V receptacles) and Flex-S3 field connector with 14 AWG cable.

Important: Plug-in solar requirements vary by state, utility, and local authority. A plug-in connection should not be assumed to be permitted simply because the inverter is equipped for plug-in operation. Verify all applicable electrical code, permitting, utility, interconnection and circuit requirements before installation.

Product Specifications

Safety & Outdoor Design

The HMS-360-1WM-LV uses a galvanically isolated high-frequency transformer and includes integrated rapid shutdown. Hoymiles states that the isolated transformer and rapid shutdown functionality improve system safety and help eliminate arc-fault risk.

The enclosure carries a NEMA 6 / IP67 outdoor rating and is designed to operate across temperatures from -40°F to 149°F. Fanless natural-convection cooling eliminates the need for mechanical cooling fans.

Compliance

According to the Hoymiles North American specification sheet, the HMS-360-1WM-LV is listed as compliant with:

• UL 1741
• UL 3700
• IEEE 1547

The HiFlow Pro LV series also meets ETSI EN 303 645 cybersecurity standards for enhanced privacy protection.
