Dual charging and dual protection solar inverter

What is a dual-input power converter?

The dual-input power converter provides stable power to the full-bridge inverter, ensuring high-quality output for the load. Fig. 3 illustrates the operation of the dual-input power converter in a standalone solar power system.

Can a 200 watt solar system be expanded into a microinverter?

The system can be expanded into a plug-and-play microinverter. This study presents the development of a 200 W standalone solar power generation system. The system incorporates a simple dual-input power converter, utilizing a 200 W photovoltaic (PV) panel and a battery set as primary energy sources.

What does a solar inverter do?

In a solar power system, the inverter plays a crucial role in converting the DC power generated by solar panels into AC, which is required for residential or industrial use. Depending on the system design, inverters can be either grid-tied or off-grid [12, 13].

How efficient is a 200 W PV system with a dual-input power converter?

A 200 w standalone PV system with a dual-input power converter is proposed. The proposed global MPPT algorithm achieves an efficiency of up to 99 %. The proposed inverter control strategy reduces THD to below 0.087 %. The system can be expanded into a plug-and-play microinverter.
