There are two main requirements for solar inverter systems: harvest available energy from the PV panel and inject a sinusoidal current into the grid in phase with the grid voltage. In order to harvest the energy out of the PV panel, a Maximum Power Point Tracking (MPPT) algorithm is required.
The micro-inverter employs a single inverter for each PV module, thereby providing increased control capability and fault resilience. Micro-inverters are typically deployed for systems where each PV module is rated up to 500W.
The term, “microinverter”, refers to a solar PV system comprised of a single low-power inverter module for each PV panel. These systems are becoming more and more popular as they reduce overall installation costs, improve safety and better maximize the solar energy harvest. Other advantages of a solar microinverter system include:
The experimental results for the power of 217.8W show the inverter's efficiency of 97.5% and total harmonic content of less than 3%. However, there is no isolation between the inverter and the utility grid.
