Product Overview

This chapter mainly introduces the DMU appearance, packaging accessories, technical parameters, etc.
1.1 Product introduction
PV microinverter system
1.1.1 Microinverter
Microinverter (hereinafter referred to as microinverter) converts the DC output of PV panels into AC power that meets the requirements of the grid and transmits it in the power grid, the DMU continuously collects the operating data of each microinverter port and sends it to the monitoring platform, which constitutes the module-level monitoring of the microinverter system hardware base.
1.1.2 Data management unit ( DMU )
The DMU data management unit is a key component of the microinverter system. It is the power generation information transfer station of the microinverter system, which communicates through the Sub-1 communication module with the microinverter, collects the real-time operation data of the microinverter, and sends the collected microinverter operation data through Ethernet to Hyxi monitoring service system.
A single DMU data management unit can communicate up to 400 PV modules, i.e. it can communicate up to 400 1-in-1 series of microinverters or 200 2-in-1 series of microinverters or 100 4-in-1 series of microinverters. If the DMU data management unit is installed in a place with poor communication signal the environment may cause signal attenuation, resulting in the reduction of communication devices.

• If the DMU is required to monitor as many photovoltaic modules as possible, the onsite installation of the DMU and the microinverter should follow the requirements in the user manual. The execution is performed, and the distance between the microinverter and the DMU is as close as possible to reduce obstruction.

1.2 Product model
This article mainly involves the following product models:

• HYX-DMU-W
• HYX- DMU-4G

1.3 Monitoring System
The monitoring system collects the operating data and status of each microinverter in the system through the DMU data management unit, and uses the PC or APP to provide users with module-level monitoring to realize remote operation and maintenance. It is mainly composed of components, microinverters, DMU data management unit and other devices.
