Introduction to Micro Inverters
Micro inverters are small, individual inverters that are installed on each solar panel in a photovoltaic (PV) system. Unlike traditional central inverters, which convert the DC power from an entire array of solar panels into AC power at a single location, micro inverters perform this conversion at the panel - level. This offers several advantages, such as increased energy harvest due to the ability to mitigate the effects of shading, panel mismatch, and soiling on individual panels. Micro inverters also enhance system safety, as they operate at lower DC voltages, reducing the risk of electrical shock and fire hazards. Additionally, they provide real - time monitoring of each panel's performance, enabling easier system maintenance and troubleshooting.
