Page 13: Product Overview
Product Overview Microinverter System Description A microinverter system is composed of PV grid-connnected microinverters, PV modules, and grid. Microinverter data are transmitted to SolaX monitoring platform SolaXCloud. Figure 2-1 System overview diagram X1-Microinverter 2 in 1 series The X1-Microinverter 2 in 1 series manages system energy. Microinverters convert the direct current power generated from the PV modules into grid-compatible AC current. - Page 14 Product Overview Tracking (MPPT). The X1-Microinverter 2 in 1 is integrated with MPPT, which means that even though a PV module runs abnormally or is shaded, other modules won't be affected and can operate the unshaded string at maximum efficiency point. This function plays an important role to improve the efficiency of a photovoltaic (PV) generation system.
