How is the vehicle in space powered?On April 16, 2022, China's Shenzhou XI-3 spacecraft completed its manned space station mission and landed in Inner Mongolia, China. Where did the three astronauts get the electricity for their 180-day mission? The spacecraft also has a "PV + energy storage" systemThat's right! A PV off-grid system, which we take for granted, is also being used in big space vehicles. The system requires solar cells and energy storage batteries. Solar cells in space are solar cell wings. As the aircraft orbits the Earth, when it reaches the sun's illumination area, the solar cell wings will convert the solar energy into electricity for the aircraft to use, while storing energy in the energy storage battery. When the vehicle orbits in the shadow of the Earth and the sun, the battery outputs electricity to power the vehicle."PV + energy storage" is the most important energy supply method for space explorationGenerally speaking, manned spacecraft can be powered by solar power, nuclear power, fuel cells and batteries. The choice depends on a number of factors, such as the power of a manned spacecraft and the length of time it will stay in space.Solar energy is always with us in the universe we have reached so far. The solar energy in the universe is 1.4 times that on earth. Compared with the danger of nuclear energy and the limitation of fuel cells and batteries, solar energy can be said to be the most perfect choice. We may never reach the boundary of the universe, but we must also start from scratch, from small to big, and boldly explore the mysteries of the universe. Fangpusun has been in the photovoltaic industry for more than ten years, and its solar controllers and inverters are sold well in more than 190 countries and regions. Maybe Fangpusun cannot provide services for human space exploration, but Fangpusun can provide excellent photovoltaic products for every person, every family and every company on the earth. Just like Fangpusun's Xtender series inverters can power any kind of battery and any scenario!   

Fangpusun's sales champion -- Flexmax seriesFangpusun has unknowingly passed its 10th year and we are now a full-fledged manufacturer of solar charge controllers and inverters. We have launched a series of solar controllers such as MPPT(Blue), MPTP-D, Flexmax and VarioTrack to the market. All of these solar charge controllers have achieved good market results, among which Flexmax is the sales champion. Why is Flexmax number one? Let's take a look at the user feedback below：Take another look at the actual scene that one of our dealers sent us：We can see that our Flexmax series solar charge controller is a reliable product in the eyes of dealers, which can bring good sales to dealers because of its low price and strong product strength. The Flexmax series charge controller can work normally in the range of - 40℃ to 60℃ and can be protected from moisture and dust. Fangpusun promises to replace and not repair the quality problem within the warranty period.In the hands of our end users, the Flexmax family is a solar charge controller that is easy to install and use. Flexmax products have an LCD display that allows you to view and set parameters. The built-in intelligent heat management system can effectively dissipate heat and ensure the long and stable operation of the controller. Low price and high quality are very attractive! 

The importance of fans in inverters and solar charge controller The fan is a cheap and easy to buy item, the fan in the inverter and solar charge controller is mainly to meet the cooling needs of the main power device. There are many factors affecting performance, but heat dissipation is the most important one. The temperature at which inverters and solar charge controllers operate affects stability and life.(Built-in fan of Fangpusun VarioTrack series solar charge controller)Cooling fan protection remains a problem. In photovoltaic practice, we often see many inverter/solar charge controller  fan blade dust, fan running noise increases, cooling down, and some fans even due to go into rain or dust accumulation is serious and the damage can't work, the serious influence/solar PV inverter/solar charge controller running status, shorten the service life of the inverter.The cooling fan increases the energy consumption and noise of the inverter/solar charge controller itself, and the high-speed operation of the cooling fan also shorts the service life of the fan. In order to solve these problems, the energy consumption caused by increasing the cooling fan is reduced as far as possible, and the stability of the inverter is improved. Fangpusun Xtender series inverter adopts intelligent air cooling operation technology for fans, automatically adjusts fan speed according to the internal temperature of the inverter, reduces noise, and achieves the purpose of good heat dissipation performance and low power consumption.(Built-in fan of Fangpusun Xtender series Inverter)Fangpusun's Xtender series inverters XTM, PSM, XTH and PSH have 3 built-in fans, while Flexmax and VarioTrack series solar charge controllers have 1 built-in fan respectively. While ensuring heat dissipation, the excellent internal design makes it easy to clean and maintain the fans. As fragile products, Fangpusun products are easy to replace and operate. Although this is only a small detail, it provides convenience for the operation and maintenance of the product heat dissipation system and even the whole system. I believe that the convenience of operation and maintenance can improve the life of the inverter and solar controller to a certain extent.

For the perfect birth of a off grid hybrid solar inverter, flexible and multiple high-quality raw materials are needed. Explained as substances used in the primary production of goods, they are often altered for use in various processes prior to being used in the manufacturing process. Sometimes, inevitable chemical reactions between different raw materials with various chemicals included may occur. This requires the workers of the manufacturing company to be equipped with proficient skills and the abilities to tackle emergencies. With accumulated rich experience, Wenzhou Xihe Electric Co.,LTD. is well-known for the integration of R&D, production, and sales of off grid hybrid solar inverter. Fangpusun is mainly engaged in the business of off grid hybrid solar inverter and other product series. It is extensively acclaimed in the market owing to stylish patterns and designs. The automatic load reconnection function makes it particularly appealing. Fangpusun is always here to offer a hand for design and installation for 48v inverter. It is renowned for excellent load adaptability.Our passion for the cause motivates us to fulfill our mission and pursue perfection of PROsine Inverter. Please contact.
