Overview
The Hoymiles HMS-300-1T is a single-phase 1-in-1 microinverter for one module of 240-405+ Wp, with 1 independent MPPT and a rated output of 300 VA. Each input takes a maximum of 60 V and 12 A (short-circuit current 20 A); the MPPT range is 16-60 V and the start-up voltage 22 V. Peak efficiency is 96.7% and nominal MPPT efficiency 99.8%; rated output current is 1.30 A at 230 V.
Read the full description
Hoymiles specifies a maximum of 19 units per AC branch on 2.5 mm², 26 on 4 mm² and 30 on 6 mm² cable; always check local requirements. The microinverter communicates over Sub-1G with a Hoymiles DTU (DTU-Pro-S, DTU-Lite-S or, for systems of up to four modules, DTU-WLite-S) and is monitored in S-Miles Cloud. AC cabling uses the Flex-S3 cable system (formerly the HMS cable system) with connection cables, trunk connectors, sealing cap and disconnect tool.
Enclosure 182 x 164 x 30 mm (W x H x D), 1.75 kg, IP67 for outdoor mounting, natural convection without fans and an ambient range of -40 to +65 °C. Galvanically isolated HF transformer, compliant with EN 50549-1:2019, VDE-AR-N 4105:2018 and VFR 2019. Hoymiles provides a 12-year warranty under its EU warranty terms for microinverters.
