2. Product Introduction
2.1 Photovoltaic On-Grid System
The on-grid system diagram of HYX-M500-SW series microinverter is as follows:
A textual description of the diagram shows a PV module connected to a microinverter. The microinverter is connected to a meter, which is then connected to the grid. A load is also shown connected to the grid. The microinverter has connections for PV module, AC branch connector, and antenna. The diagram also indicates the cable used for the miniature inverter with color coding: PE (Green-yellow), N (Blue), L (Brown).
2.2 Microinverter
HYX-M300-SW, HYX-M400-SW, HYX-M500-SW series are 1-in-1 microinverters, which can connect one photovoltaic module. They are module-level photovoltaic inverters with module-level monitoring function.
The whole system consists of two parts: photovoltaic on-grid power generation system and photovoltaic monitoring system. The photovoltaic on-grid power generation system includes photovoltaic modules, microinverter, AC cable, and other accessories. The microinverter is the core product of the 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 the photovoltaic system, regardless of 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.
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.
2.3 1-in-1 Microinverter System
The DC side can choose a microinverter series according to the number of connected photovoltaic modules. As shown below:
Diagrams illustrate 1-in-1, 2-in-1, and 4-in-1 configurations. The manual focuses on the 1-in-1 series.
This series of HYX-M500-SW has outstanding performance in the 1-in-1 series, with an output power up to 500VA. Each microinverter can be connected to one photovoltaic module. It has independent MPPT and module-level data monitoring functions, high power generation, and easy and convenient maintenance features.
2.4 Communication Technology
HYX-M500-SW microinverter series adopts a new Wi-Fi wireless communication solution. Wi-Fi communication solution: It operates in the 2.4GHz frequency band, and the transmission distance is weaker than the Sub-1G frequency band. It does not need additional communication equipment and can directly communicate with Hyxi Cloud.
2.5 Product Features
- Maximum output power 500W.
- Module-level MPPT, the peak conversion efficiency reaches 96.7%.
- IP67 enclosure, 6000V surge protection for higher reliability.
2.6 Inverter Size and Terminal Instruction
A diagram shows the dimensions of the microinverter: Width 188mm, Height 255mm, Depth 178mm. It also indicates connection points: A: AC Branch Connector, B: Antenna, C: DC terminal. The overall dimensions including the cable are shown as 557mm.
3. Installation
Each microinverter is installed on a mount just below the solar module panel. The low-voltage DC line on the panel side of the solar module can be directly connected to the microinverter, but it must be protected from direct sunlight, rain, snow, ultraviolet rays, etc. A clearance of at least 20mm should be left around the microinverter enclosure to ensure ventilation and heat dissipation.
