HOYMILES HM-400 Microinverter 0.4kW 1PH


HOYMILES Microinverter HM-400 (Single-Phase)

Hoymiles microinverters are designed to work with 1, 2, or 4 PV panels. With independent operation of each module, the solar installation achieves the highest possible efficiency.
A characteristic feature is the ability to install the modules directly under the PV panels.

Device features:

IP67 waterproof rating
Low startup voltage of only 22VDC
High surge protection
Module-level MPPT
Control capability through a free application.
Additionally, each inverter can be connected to a web server where the status of the PV installation can be monitored in real-time.
The installation can be expanded in a modular way by adding additional PV panels equipped with microinverters.

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