Description
Hoymiles HMS-350-1T 350W Single-Module MLPE Microinverter
The Hoymiles HMS-350-1T is a single-module (1-in-1) module-level power electronics (MLPE) microinverter designed for panel-level power conversion across commercial and residential solar arrays. Engineered to support high-powered PV modules ranging from 280W to 470W+, the hoymiles hms-350-1t handles continuous input currents up to 13A (with a 20A short-circuit current rating), making it compatible with modern high-efficiency PV panels.
Operating over Sub-1G sub-gigahertz wireless communication, the hoymiles hms-350-1t pairs with Hoymiles DTU-Pro-S monitoring gateways to provide module-level telemetry via the S-Miles Cloud platform. Encapsulated in a fanless NEMA 6 (IP67) outdoor enclosure, it satisfies NEC 2017/2020 690.12 rapid shutdown compliance, UL 1741 SB certification, and California Rule 21 grid standards.
