The installation personnel of the solar power generation system should carefully read and observe the manufacturer’s instructions. Therefore, when installing the  solar controller , the solar array should be covered with opaque cloth, and the load will be disconnected to protect the equipment and installation personnel, and the installation position should be well ventilated, so as to prevent the heat dissipation components from being too high. The solar inverter and the controller are much the same. But it should be noted that when it connects the DC cable to the inverter input terminal, we must pay attention to the polarity of the inverter and confirm that the positive and negative polarity have been accessed correctly. In addition, the specific wiring and debugging methods of the  solar MPPT charge controller  and inverter need to be detailed to refer to the technical instructions carried by the solar photovoltaic system. SOROTEC Solar MPPT Charge Controller ...

A safe and reliable DC switch The household power station is very complex, location is also relatively remote, once the component of short circuit grounding fault, the after-sale staff can’t arrive at once, may cause a fire or electric shock, this allows the owner to disconnect DC switch (which operation is very simple) to avoid further escalation of fault. Minimize the noise The household with  solar inverter  is installed in the home. If noise is produced in the operation, it will bring great inconvenience to people’s life. The inverter’s voice comes from the fan and inductor. The solar inverter should be designed without fan, and there is no fan inside and outside to eliminate the biggest noise source. The inductor is glued together and put into an aluminum case box separately, so as to reduce the current and the vibration sound of the inductor. Take a variety of display methods It need a LCD display, intuitive and convenient. It is suitable for some users without smar...

After decades of development, photovoltaic power generation have made some achievements. Photovoltaic grid connected power generation system is composed of photovoltaic array,  solar charge controller  and  grid connected inverter . It converts the direct current generated by  solar inverter  to grid connected inverter and converts it into a power generation system that meets the requirements of grid. Photovoltaic grid connected power generation system can supply power directly into the power grid, but the stability of the power generation process is poor, and it will also have a certain impact on the power grid. Photovoltaic grid connected power generation and load characteristics Photovoltaic power generation is greatly affected by the environment, and its power generation will increase with the increase of illumination. Generally, when the sunshine is shining, the power peak is generally at the strongest point of sunshine, which is about 10:00 ~ 14:00. Whe...

Under the outdoor working environment, the waterproof protection of  telecom power supply  is must, but if the product only satisfies the IPX3 (rain) protection level which is not enough, it need to prevent the invasion of rainstorm when it is raining or snowstorm. The waterproof protection only considers the prevention of rainwater, and the prevention of water immersion is not to be considered. In some areas which often occur flood and waterlogging, the platform for outdoor communication stations should be built above 2 meters or other highlands, so that the equipment of telecom stations will not be immersed in water during disasters. SHW48200 48VDC Outdoor Power Supply MPPT Off-Grid Telecom Station  Solar Hybrid System ■Adopt advanced MCU microprocessor control technology. ■Advanced MPPT Technology,High converting efficiency higher than 97% for minimizing energy loss. ■Reversed current protection at night, over voltage and reverse polarity protection. ■Capable of...

In the past 2017, there was less snow in our country, in addition to snow in the northeast and the northwest part of China, the amount of snow in other parts of the region is less. However, the weather situation had changed greatly at the beginning of the 2018. The Middle East of our country will have the largest and strongest rain and snow weather. Low temperature will bring about changes in the physical properties of electronic components, and this change tends to develop in a disadvantageous direction. Blizzard has great impact on photovoltaic power station. Too thick snow will cause excessive icing of components, affect the power generation and life of the system, resulting in the decline of power generation and even stop work. For hybrid off grid solar inverter , it is also a severe test. Severe cold climate conditions may make on grid off grid hybrid inverter work unstably, such as failure to start, frequent alarm, low power generation and so on. How to choose hybrid off...

Thank you for your support and trust in 2017,and congratulate you on the arrival of the New Year and to extend to you all my best wishes for your perfect health and lasting prosperity in 2018.

First, the demand for  UPS  energy saving and environmental protection is increasing. In the situation of international oil price volatility and global energy shortage, material recycling and no pollution to the environment, will become the future development direction of power supply products, with the continuous improvement of the level of information, and in the construction of the data center more emphasis on “green” concept. Especially in the UPS innovation technology and the application of air conditioning in the machine room, more and more modular design is adopted. The modular design of UPS and refrigeration system can avoid energy consumption. By modularized flexible expansion, we can reduce user’s investment in equipment and save energy. Secondly, the UPS distribution market still occupies the main position. The main body of the distribution market consists mainly of UPS dealers and industry agents, and the UPS dealers here include professional power suppliers and...

The  outdoor cabinet  is a closed iron box. When the cabinet is exposed to the summer sunshine, the solar radiation heat will be transmitted into the cabinet through the sun drying surface. The temperature inside the cabinet will rise, which will cause the  rectifier module  or  inverter  module of the product and UPS will be shutdown due to over temperature protection. At the same time, the temperature inside the cabinet is too high, which is very unfavorable to the battery. No matter the adsorption type or the colloid sealed lead acid battery will cause the loss of water in the battery medium due to the high temperature. When the battery medium is lack of water, the conversion efficiency of the battery will decrease, and the failure of the battery is not output.
