The output of 87GW in China increased by 34.3%. The global…

Matters needing attention when installing solar controller and inverter in solar system

图片
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.

What should be paid attention to the selection of solar inverter for home

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 smart phones. Physica…

What is the impact of PV grid connected power generation on the power grid

图片
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. When PV grid connected to large capa…

Waterproof protection of telecom power supply

图片
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.
