Hoymiles HMS-900-2T Microinverter Module Inverter

The HMS-900 (MPN: HMS-900-2T) from Hoymiles is the perfect micro inverter for your balcony power plant. The compact lightweight (only 3.2kg) is suitable for solar power production with up to two solar panels up to a power of 360 to 600+W each. Just like all other micro inverters from Hoymiles, it is suitable for long operating hours and wide PV panel application, as its start-up is very low (only 22V) and the DC input range of the operating voltage (16-60V) is extremely wide.

Compared to the previous model from the HM series, the HMS-900 offers more safety for rooftop solar power plants through quick shutdown and isolated transformer. The new sub-1G radio solution enables more stable communication with the Hoymiles gateway DTU.

• Complies with EN50549-1:2019, 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
• Optionally possible: Monitoring via S-Miles App or S-Miles Cloud
  A DTU Lite-S is required for system monitoring.
  To have the option of changing settings in addition to monitoring, a DTU Pro-S is required instead of the DTU Lite-S.

Optimum reliability

Micro-inverter systems are inherently more reliable than conventional inverters. The decentralised design of a microinverter system ensures that the entire PV system will not fail in the event of a malfunction. Hoymiles microinverters are designed to operate at full power in ambient temperatures up to +65°C (150°F). The micro-inverter housing is designed for outdoor installation and complies with protection class IP67.

Simple structure

PV systems with Hoymiles microinverters are very easy to plan. You do not need to install cumbersome conventional inverters. Each microinverter can be quickly mounted on the PV mounting rack or directly under the PV module. The PV module is connected to the microinverter directly on site, eliminating the risk of people being exposed to dangerously high DC voltage.
