Microinverters are often used as an alternative to string inverters to perform the DC to AC power conversion at solar panel level in residential photovoltaic systems. A solar micro inverter helps maximize energy yield and mitigate problems related to partial shading, dirt or single PV panel failures. A microinverter is composed of a DC-DC converter implementing Maximum Power Point Tracking (MPPT) and a DC-AC inverter to shape current and voltage for injection into the AC grid. Data – including voltage, current and power generated - from all microinverters in the installation are collected and logged by a concentrator and then dispatched to a local or remote monitoring and control access point.
