Microinverter HMS-900-2T 1F Hoymiles

Hoymiles HMS-900-2T photovoltaic microinverter

is an advanced solution designed for superior performance and reliability in photovoltaic systems. The device features a maximum output power of up to 900 watts, placing it among the best 2:1 microinverters on the market. Each HMS-900-2T microinverter has two independent MPPT inputs, allowing two PV modules to be connected, ensuring optimal energy management and maximum efficiency under different weather conditions.

Independent monitoring of each PV module by the Hoymiles system, using Sub-1G wireless technology, ensures stable and secure communication, regardless of the installation environment. The Reactive Power Control system in the HMS-900-2T microinverter meets international standards such as EN50549-1:2019, VDE-AR-N 4105:2018, Ul1741, confirming its compliance with safety and efficiency requirements.

The HMS-900-2T microinverter is distinguished by a maximum efficiency of 99.8%, which minimizes energy losses during operation. The device operates over a wide input voltage range of 16 to 60 volts, allowing flexible adaptation to different photovoltaic module configurations. The robust design, measuring 261 x 223 x 31 mm and meeting IP67 standards, guarantees protection from adverse weather conditions and ensures long-term reliability.

The HMS-900-2T microinverter is mounted directly under the photovoltaic panels for space-saving, quick and easy installation. Passive fanless cooling increases the life of the device, eliminating the risk of failures related to mechanical components. An adjustable power factor and an LED on the housing indicating the unit’s status are additional features that make it easy to use and monitor system operation.
