Hoymiles HMS-300-1T Microinverter Module Inverter

The Hoymiles HMS-300 (MPN: HMS-300-1T) is the ideal microinverter for your balcony power plant. Its light, compact weight (only 1.75 kg) is suitable for producing solar energy from 240 to 405+W each. Like all Hoymiles microinverters, it is suitable for long operating hours and a wide application of PV modules, because the start-up is very low (only 22V) and the DC input voltage range (16-60V) is very wide.

Compared with the previous model in the HM series, the HMS-300 is now 0.23 kg lighter and offers greater safety for rooftop solar power plants thanks to its quick disconnection and insulated transformer. The new sub-1G radio solution ensures more stable communication with the Hoymiles DTU gateway.

• Simple installation
• Long service life
• Compliant with EN 50549-1 : 2019, VDE-AR-N 4105 : 2018, VFR2019, IEC/EN 62109-1/-2, IEC/EN 61000-6-1/-2/-3/-4, IEC/EN 61000-3-2/-3
• Optional: monitoring via S-Miles App or S-Miles Cloud.
  A Lite-S DTU is required for system monitoring.
  To be able to modify parameters in addition to monitoring, a DTU Pro-S is required instead of a DTU Lite.

Optimum reliability

Microinverter systems are intrinsically more reliable than conventional inverters. The decentralised design of a microinverter system ensures that the entire photovoltaic system will not fail in the event of a fault. Hoymiles microinverters are designed to operate at full power in ambient temperatures of up to +65°C (150°F). The microinverter housing is designed for outdoor installation and meets IP67 protection class.

Simple structure

Photovoltaic systems equipped with Hoymiles microinverters are very easy to plan. There is no need to install bulky conventional inverters. Each microinverter can be quickly mounted on the PV mounting frame or directly under the PV module. The PV module is connected to the microinverter directly on site, so there is no risk of people being exposed to dangerously high DC voltage.
