HOYMILES HMS-900-2T Microinverter 0.9kW 1PH

HOYMILES Microinverter HMS 900-2T (1-phase)

The output power reaching 900 VA positions the new Hoymiles microinverter series, HMS-900, at the forefront of 2-in-1 microinverters.
Each microinverter can connect up to 2 panels with independent MPPT and monitoring to maximize PV production in the installation.
The new solution based on a wireless network below 1 GHz enables more stable communication with the Hoymiles DTU gateway.

Features:
High-power 2-in-1 microinverter with an output power of up to 900 VA
Reactive power controller compliant with EN 50549-1:2019, VDE-AR-N 4105:2018, VFR2019, etc.
Increased safety for rooftop solar stations due to compliance with rapid shutdown standard and galvanically isolated transformer
Independent MPPT and monitoring for higher energy yield and easier maintenance
2-in-1 design allows for faster installation
Wireless solution based on a network below 1 GHz enables stable communication in commercial and industrial environments.
