Renewable Energy - Solar Energy

Renewable energy is defined as energy that is derived from renewable resources that are renewed naturally on a human timescale and may be harvested. It encompasses a variety of energy sources such as solar, wind, tides, waves, and geothermal etc. To cover requirements of renewable energy, the IEA predicts that renewable energy will account for over 30% of global power generation by 2030, with solar PV accounting for 10%. Over 50% (solar PV: 20%) by 2040, and over 80% (solar PV: 60%) by the end of this century.

Among all the renewable energy resources, solar PV power has risen to become the dominant alternative energy source because it is a cost-competitive, reliable, and environmentally friendly source of electricity. Throughout the day, the sun provides significantly more energy than humans require powering everything on the planet. It generates more than enough energy to supply the demands of the entire world's population, and, unlike fossil fuels, it is not expected to run out very soon.

Solar photovoltaic directly converts sunlight into electrical energy. A photovoltaic (PV) cell is made of semiconductor materials, and a photovoltaic panel is built by connecting these photovoltaic cells. When the sun's rays strike the surface of a solar PV cell/module, they are converted into electricity.

MORNSUN has launched the PV Series products with two families of DC-DC converters with extremely wide input ranges because it is possible to save a significant amount of money by connecting arrays in series (lower copper losses). The PV Series has input ranges ranging from 100 to 1000 volts direct current (PVxx-27BxxR2) and 200 to 1500 volts direct current (PVxx-29xx), it has been designed primarily for use in photovoltaic array combination units.

The MORNSUN PVxx-29Bxx series of ultra-wide input DC-DC converters has been awarded the prestigious Aspencore World Electronics Achieved Award for the best power management/voltage converter of the year. These converters work normally in harsh environments with operating temperatures ranging from -40°C to +85°C and at altitudes of up to 5000m. Furthermore, the PVx-29Bxx series includes a variety of protections to improve system safety, including input under-voltage, reverse voltage, output short-circuit, overcurrent, and over-voltage protection.

DC/DC converter series are widely used in both domestic and international markets. Until now, the PV series products have ranges of 100 to 1,000V or 200 to 1,500V and output powers of up to 350 Watts.

The wide input voltage range of 300-1500VDC from high-voltage Strings BUS substantially simplifies power system design and there is no need for extra PV panels, more efficient electricity generation, and better economics

The PV series' wide input operating voltage makes them ideal for use as controllers in combiner boxes (which connect multiple pa series to reduce cable diameters and costs), actuator position control, and telemetry systems.

The PV series' applications are not limited to the solar industry (typical applications are PV combiner box and PV inverter). With the addition of a bridge rectifier and a small smoothing cap, you can create a converter that can operate on both single and two-phase systems.
