Micro Converter (DC-Optimizer) System

The micro converters are used in lower power applications and installed on each PV panel. This approach provides the advantage of individual optimized MPPT (hence this configuration is also called DC-optimizers). The DC-DC converter converts the PV panel output DC voltage up or down and it is then fed to a "central" DC-AC inverter stage.

Distributed Maximum Power Point Tracking System (D-MPPT)

In low power (190W~500W) distributed-MPPT systems, such as the micro inverter and micro converter architectures, the MPPT is performed at each PV module. These low power systems can be integrated into the frame of the PV module. The micro inverter is often called an "AC-module" and the micro converter is often called a "DC-Optimizer."
