Hoymiles HMS-360-1WM-LV HiFlow Pro LV 1-in-1 series plug-in microinverter

The Hoymiles HMS-360-1WM-LV is a 360 VA plug-in microinverter from the HiFlow Pro LV 1-in-1 series, designed for balcony, terrace, patio, and garden solar. It connects to a single PV module and to a standard 120 V household outlet through the included plug-and-play cable, so there is no DC combiner, string wiring, or separate gateway to install.

A built-in Wi-Fi and Bluetooth module handles both commissioning and ongoing monitoring through the S-Miles Home app, which means no additional DTU is required to get the system online. The unit is fanless, outdoor-rated, and mounts directly to the PV module bracket.

Key Features

• 360 VA rated output — sized for a single module in the 280 to 470+ W range, so it pairs with most current residential-format panels without clipping the array.
• Built-in 2.4 GHz Wi-Fi and Bluetooth — commission locally over Bluetooth or remotely over Wi-Fi. No separate DTU gateway to purchase, mount, or wire.
• Included plug-and-play cable — 14 AWG cable with a standard Type B plug on one end and a Flex-S3 field connector on the other. 
• Single MPPT with a 16 to 60 V tracking range — a 22 V start-up voltage brings the unit online early in the day, and 99.8% nominal MPPT efficiency keeps tracking losses low across changing light.
• Galvanically isolated HF transformer topology with integrated rapid shutdown — isolation between the DC and AC sides is built into the unit rather than added as a separate device.
• NEMA 6 / IP67 enclosure, cooled by natural convection — no fans to fail, and a −40 to 149 °F operating range that covers most North American installations.
• Listed to UL 1741, UL 3700, and IEEE 1547 — the certifications utilities and inspectors typically ask for on grid-connected equipment.

The HMS-360-1WM-LV is a grid-tied unit with a 120 V nominal AC output and a 90 to 150 V operating range, running at 60 Hz nominal with a 55 to 65 Hz range. Power factor is greater than 0.99 by default and is adjustable from 0.8 leading to 0.8 lagging, with total harmonic distortion under 3% at nominal power. Rapid shutdown is integrated into the unit. Nominal voltage and frequency ranges can vary with local utility requirements, so confirm the settings your utility expects before commissioning.

Setup runs through the S-Miles Home app, available for both iOS and Android. The app supports two paths: a remote connection that registers the microinverter to your account and your home Wi-Fi network for cloud monitoring, and a direct Bluetooth connection to the unit for local commissioning or troubleshooting without a network. Record the serial number from the enclosure label before mounting — you'll need it to add the unit to a system in the app.

This is a single-module product for people who want real solar production without a roof array, a permit-heavy install, or a full system design: apartment and condo balconies, patio and terrace, garden and ground-mounted panels, and small starter installations where a homeowner wants to test the water before committing to something larger. It also suits renters and anyone in a situation where the array needs to come down and move.
