Step wave solar powered inverter introduction

The waveform of the output of the solar powered inverter is step wave, and there are many kinds of different lines to output step wave, and the number of the output waveform is very different. The advantage of the step wave solar energy inverter is that the output waveform is significantly improved than the square wave, the higher harmonic content is reduced, and the modified sine wave can be realized when the step is more than 17. When there is no transformer output, the efficiency of the whole machine is very high. The disadvantage is that there are more power switches used in the step wave superposition circuit, and some of them are also required to have multiple sets of DC power input. These bring trouble to the grouping of the solar cell array and the balance charging of the wiring and the accumulator. In addition, the step wave voltage still have some high-frequency interference on the radio and some communications equipment

How to maximize the efficiency of your UPS

1.Use of AC voltage regulator After using  UPS power supply , there is no need to add AC voltage regulator. If it must be added, it should be added to the front level of UPS, that is, the mains power first passes through the AC voltage regulator, then through the ups, and then to the load. 2.Battery balanced charging skills At present, valve regulated lead-acid battery (VRLA) used in many ups power supply is called maintenance free battery from the beginning, which gives users a misunderstanding that it seems that this battery is durable and does not need maintenance at all. Under this kind of misleading, many users have not carried out maintenance and management since they installed the battery. When the battery in UPS power supply meets the following conditions, the battery shall be charged evenly: when the terminal voltage is lower than the specified calibration voltage due to excessive discharge. For 12 V small sealed lead-acid batteries, the discharge calibration voltage is 10.

On Oct 15th 2019, as one of the most important trade promotion platforms for Chinese enterprises to expand the global market, Canton Fair in Guangzhou focused on highlighting innovation driven, and “independent brand” became a high-frequency word of Canton Fair. Xu Bing, a spokesman for the Canton Fair and deputy director of the China Foreign Trade Center, said that the domestic and foreign environment faced by China’s foreign trade development this year is more complex and uncertain. The majority of exhibitors accelerated quality improvement and innovation, and continued to make efforts in technology research and development, product innovation, brand cultivation, etc., with high technology, high quality, high added value and independent brand products emerging. Many independent innovative R & D products are welcomed by the market. At the same time, purchasers are less sensitive to price and pay more attention to the technology, brand, quality and service of products. In

The development of China electric vehicle charging pile

Now in China, the charging station infrastructure construction is in peak, the attention of the government and enterprises in the charging station professional services is recharge or changing the power of choice, the China charging station integrated services have yet to be developed. 1, charging station successful operation case: China existing two largest most mature electric vehicle charging station is Beijing Olympic Games charging stations in the Shanghai World Expo and charging stations, the two charging stations at present is for electric city bus to provide fast battery replacement service, two charging stations are currently does not belong to the formal business operations, but governmental organizations under the pilot run. After two charging stations in common is dominated by a group of local bus operation, charging station founded and funded by a major national special fund and the place, running electric bus ownership bus group, Beijing Olympic charging station power
