This reference design implements single-phase inverter (DC/AC) control using a C2000TM microcontroller (MCU). The design supports two modes of operation for the inverter: a voltage source mode using an output LC filter, and a grid connected mode with an output. . 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 microinverter. . Events: grid-connected, unplanned islnding at 10 s, planned reconnection at 15 s, reconnect to the grid. Strategy II has slightly better transients in the output current. Rather than linking every solar panel in an installation to a central inverter, solar micro inverter-based. . Microchip's Grid-Connected Solar Microinverter Reference Design demonstrates the flexibility and power of SMPS dsPIC® Digital Signal Controllers in Grid-Connected Solar Microinverter systems.
