1.According to the load type and power of the user to confirm the power of the  solar off grid inverter , the household load is generally divided into inductive load and resistance load. The load of the washing machine, air conditioner, refrigerator, pump, smoke pump and so on is inductive load, and the starting power of the motor is 5-7 times of the rated power. When calculating the power of the inverter, the starting power of these loads should be taken into account. The output power of the inverter is greater than that of the load. For monitoring stations, telecom stations and other stringent requirements, the output power is based on the sum of the load power. But for poor families in general, considering that all the loads can not be opened at the same time, in order to save cost, the sum of the load power can be multiplied by the coefficient of 0.7-0.9. 2.Confirm component power according to user’s daily power consumption. The design principle of the component is to meet t...

The main points of dust proof and waterproof design for  outdoor cabinet : mainly for three places to carry out sealing treatment, so that the environment and the outside environment in a certain degree of isolation, to achieve the final design purpose. First of all, there are good dustproof measures for the cabinet to ensure the normal operation of the equipment. We begin with the seams of the cabinet, the joint part, the line interface, the design of the air duct and the fastening parts of the fasteners, because the dust and water in various environments enter the cabinet by these ways. Main points of dust proof and waterproof design of cabinet 1.Air inlet and outlet: using maze structure and dustproof net to achieve dustproof and waterproof purposes. 2.The gap between the air duct joint: install the sealing strip or apply the sealant to achieve the purpose of protection. 3.Cabinet door: install sealing strip (EPDM) to achieve the purpose of dustproof and waterproof. 4.Lock ...

1.Natural heat dissipation The cooling method of natural heat dissipation of  solar inverter  refers to the purpose of realizing the temperature control of the local heating device to the surrounding environment without using any external auxiliary energy. It usually includes three main heat transfer modes, heat conduction, convection and radiation, in which the convection is dominated by natural convection. Natural heat dissipation or cooling is often applied to low power devices and components with low temperature control and heat flow density, and sealed or densely packed devices are not suitable for other cooling technologies. At present, the single-phase inverter and the three-phase inverter under 30kW, most of the manufacturers can achieve natural heat dissipation, and a few three phase inverters of 100kW can also achieve natural heat dissipation. 2.Forced heat dissipation The cooling method of forced cooling is mainly by means of fans and other forced devices around ...

High temperature is the main factor that causes the most likely failure of electronic devices including UPS. At high temperature, the leakage current of the device increases and the voltage decreases. According to Arrhenius’ law, when the ambient temperature is 25 degrees centigrade, the life of components or equipment is reduced by half at 10 degrees centigrade. When the temperature rises according to the arithmetic gradient of 10 degrees, the life of components or equipment will decrease which follow 1/ (n=1, 2, 3…) the law of geometric progression. And the temperature rise inside the machine comes from the power consumption of every circuit in the machine. Transformer is one of them. If there is no transformer, the power consumption can be reduced. So in this sense, because of the existence of transformer, to a certain extent, the reliability of the system is reduced. The mistake here is to confuse the mechanical stability and electrical performance of transformers. The stability...
