Integrated Project Micro Inverter

What is a solar micro inverter?

Solar micro inverters are an emerging segment of the solar power industry. Rather than linking every solar panel in an installation to a central inverter, solar micro inverter-based installations link smaller, or “micro,” inverters individually to each solar panel.

What is a grid-connected solar microinverter system?

A high-level block diagram of a grid-connected solar microinverter system is shown in Figure 4. The term, “microinverter”, refers to a solar PV system comprised of a single low-power inverter module for each PV panel.

How much power does a solar microinverter support?

The solar microinverter is designed to support 215W out-put power at nominal input voltages (25 VDC-45 VDC). To ensure that the microinverter does not operate at an output power greater than 215W, a software clamp on the maximum allowable output current has been designed, based on the measured peak AC voltage.

What is a solar microinverter reference design?

The Solar Microinverter Reference Design implements an interleaved active clamp flyback converter. An inter-leaved topology shares the input/output current which results in lower copper and core losses. Also, the output diode conduction losses are reduced to help improve overall efficiency.
