HOYMILES HMS-350-1T Microinverter 0.35kW 1PH


HOYMILES Microinverter HMS 350-1T (1-phase)

With an output power of up to 350VA, the new Hoymiles HMS-350 microinverter ranks among the top 1-to-1 microinverters.
Each microinverter can be connected to a single PV module with independent MPPT and monitoring, enabling greater energy efficiency and ease of use.

The new Sub-1G wireless solution allows for stable communication in installations in any environment.

Sub-1G wireless solution enables stable communication in commercial and industrial installations
Excellent flexibility, fast installation, and good adaptability to different module configurations
High-power 1-to-1 microinverter, achieving up to 500 VA of output power
Reactive Power Control system meets the requirements of EN50549-1:2019, VDE-AR-N 4105:2018, UL1741, etc.
Safe for rooftop solar stations equipped with an isolated transformer resistant to sudden interruptions.

For each installation built with microinverters, a Hoymiles monitoring module - MI-PRO DTU Module with RS485 port - should be selected (required for connection to the network).

Additionally, each inverter can be connected to a web server for real-time monitoring of the PV installation's status.
The installation can be expanded modularly by adding additional PV panels equipped with microinverters.
