Microinverter is a type of photovoltaic inverter used to convert direct current (DC) generated by a single solar module to alternating current (AC). Unlike central inverters that manage output from multiple solar panels, micro inverters operate on a per-panel basis, enhancing energy harvest and providing real-time monitoring of individual panel performance. This technology mitigates the negative impact of partial shading, debris, and panel mismatch on system efficiency.
These devices incorporate sophisticated digital algorithms to maximise power point tracking (MPPT) for each module. By operating independently, they allow for more flexible installation and system design, improving potential locations for solar arrays on roofs with variable orientations or inclinations. The use of micro inverters can lead to increased system longevity and safety due to lower voltage systems. They also simplify the process of scaling systems, since new panels with micro inverters can be added without reconfiguring the entire array. Warranty periods for micro inverters typically exceed those of traditional string inverters, reflecting their durability and the manufacturers’ confidence in their performance.
