The whole system consists of two parts, photovoltaic on-grid power generation system and photovoltaic monitoring system. photovoltaic on-grid power generation system includes photovoltaic modules, Data Management Unit( DMU）, microinverter AC cable and other accessories. Microinverter is the core product of photovoltaic power generation system, and it has independent maximum power point tracking (MPPT) control, which can maximize the energy output of the whole solar array and maximize the power generation performance of photovoltaic system no matter how the array is arranged or when it encounters unsatisfactory conditions such as shadow occlusion, dirt accumulation, illumination deviation or mismatch in practical application.

In addition, microinverters do not require the consistency of photovoltaic modules like central and series inverters. Each microinverter transformer can be easily mounted on the rack below the panel. The panel-side low-voltage DC line can be directly connected to the microinverter, eliminating the danger of high-voltage DC voltage.

Data Management Unit( DMU):
Microinverter system power generation information transfer station, which communicates with the microinverter through the Sub-1G communication module, collects real-time operating data of the microinverter, and transmits the collected operating data of the microinverter through various communication methods to the Hyxipower monitoring service system.

Remote monitoring platform:
The operating data and working status of the inverter are transmitted through the wireless router, and the user is provided with module-level monitoring through the Web or App application to realize remote operation and maintenance.

2-in-1 Microinverter System
The DC side can choose a micro-inverter series according to the number of connected photovoltaic modules. As shown below:

This manual mainly introduces Hyxipower 2-in-1 microinverter series.

It has independent MPPT and module-level data monitoring functions, high power generation, easy and convenient maintenance features.

Communication Technology
2-in-1 Sub-1G version series microinverters adopt a new Sub-1GHz wireless communication solution.

Sub-1GHz communication scheme:
The technology has a long transmission distance and stronger anti- interference, and operates in the 868 MHz or 433 MHz frequency band.

Product Features
