Off-grid photovoltaic system become popular

發布時間：2022-7-15 文章來源：陳雪薇 Vela Chan

In the past year, the epidemic has repeated and the world's energy has become increasingly tense. As a new type of clean energy, photovoltaic systems are gradually becoming popular and developing around the world. Since 2022, orders from Europe and the United States have grown significantly, and photovoltaic solar systems of 5KW to 50KW are very popular.

Multifit Solar participated in major online new energy exhibitions this year, and carried out a series of solar system design and guidance for customers.

At present, Multifit Solar is mainly engaged in off-grid solar power generation systems. It is mainly composed of solar cell components, solar inverters, solar controllers and batteries.

The solar panel is the core part of the solar power system. The function of the solar panel is to convert the solar energy from the sun into electrical energy, and then output the direct current and store it in the battery. Solar panels on the market are divided into monocrystalline and polycrystalline.

If the current generated by the solar panel is directly charged into the battery or directly supplies power to the load, it will easily cause damage to the battery and the load, which will seriously shorten their lifespan. Based on the above situation, a controller will be added to the solar power system, and its function is to charge and discharge.

After the controller we will connect the battery. Batteries are divided into storage battery and lithium battery. The function of the battery is to store the electrical energy emitted by the solar panel when there is light, and release it when needed. Generally speaking, when charging during the day, a part of the solar power system will be used for the load, and the other part will be temporarily stored in the battery, and then released at night to continue to supply power. It can be said that in an off-grid solar system, the battery is also an integral part.

After the battery is connected to the inverter. Inverter is an essential part of solar photovoltaic system.With an inverter, direct current (battery, switching power supply, fuel cell, etc.) can be converted into alternating current to provide stable and reliable power supply for electrical appliances, such as notebook computers, mobile phones, handheld PCs, digital cameras, and various instruments; Inverters can also be used with generators, which can effectively save fuel and reduce noise; in the fields of wind energy and solar energy, inverters are even more essential. Small inverters can also provide AC power in the field by using cars, ships, and portable power supply equipment.
