Product Introduction 2.1 Photovoltaic On-Grid System The on-grid system diagram of HYX-M2000-SW series microinverter is as follows:

2.2 Microinverter HYX-M1600-SW, HYX-M1800-SW, HYX-M2000-SW series are 4-in-1 microinverters, which can connect four photovoltaic modules. 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. photovoltaic on-grid power generation system includes photovoltaic modules, 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. 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. 4 HYX-M1600/1800/2000-SW User Manual 2.
