About Microinverter 
This system is composed of a group of microinverters that convert direct current (DC) into alternating current (AC) and feed the power to the public grid. The system is designed for 4-in-1 microinverters, i.e., one microinverter is connected with four PV modules. 
Each microinverter works independently so as to guarantee the maximum power generation of each PV module. 
This setup is highly flexible and reliable as the system enables direct control of the production of each PV module
Micro Inverter:
Hoymiles new microinverter HMS-2000 series are suitable for high-powered solar panels, which rank among the highest for 4-in-1 microinverters. 
Each microinverter can connect up to 4 panels, with independent MPPT and monitoring maximizing the power production of your installation. 
With a maximum DC voltage of 65 volts, Hoymiles microinverter is a PV Rapid Shutdown Equipment and conforms with NEC-2017 and NEC-2020 Article 690.12 and CEC-2021 Sec 64-218. 
The new Sub-1G wireless solution enables more stable communication with Hoymiles gateway DTU.




DTU:

Hoymiles gateway DTU-Pro-S is a data transfer unit which collects information and data of PV microinverter using Sub-1G wireless solution and sends them to S-Miles Cloud, Hoymiles Monitoring Platform, using different communication options such as Ethernet, Wi-Fi or 4G. With DTU-Pro-S, users can easily read module-level data and alarm, realize remote operation and maintenance of PV system at any time, from anywhere on S-Miles Cloud.
