What is inverter inverter? It is a converter that converts direct current (battery, storage battery) to constant frequency, constant voltage or frequency modulated alternating current (usually 220V, 50Hz sine wave). It consists of inverter bridge, control logic and filter circuit. It is widely used in air conditioners, home cinemas, electric grinding wheels, electric tools, sewing machines, DVDs, VCDs, computers, televisions, washing machines, range hoods, refrigerators, video recorders, massagers, electric fans, lighting, etc. Due to the high popularity of automobiles abroad, inverters can be used to connect batteries and drive electrical appliances and various tools when working or traveling. The on-board inverter output through the cigarette lighter has 20W, 40W, 80W, 120W to 150W power specifications. More inverter power should be connected to the battery through the connecting line. By connecting the household appliances to the output end of the power converter, various appliances can be used in the car. The electrical appliances that can be used include mobile phones, laptops, digital cameras, cameras, lights, electric razors, CD players, game consoles, handheld computers, electric tools, car refrigerators, and inverters for various travel, camping, and medical first aid appliances, which consume a part of electric energy when working, so their input power is greater than their output power. The efficiency of inverter is the ratio of output power and input power of inverter, that is, the efficiency of inverter is the ratio of output power and input power. If the inverter inputs 100 W DC and outputs 90 W AC, its efficiency is 90%. 2、 Common faults of inverter (I) Use elimination method for low insulation impedance. Unplug all strings on the input side of the inverter and connect them one by one. Use the function of the frequency converter to check the insulation resistance to detect the problem string. After finding the problem string, check whether the DC connector has a short circuit bracket immersed in water. Or wire and short-circuit bracket. In addition, you can also check whether the component itself has black spots and the edges are scorched, causing the component to leak to the ground grid through the frame. （2） Low bus voltage is a normal problem if it occurs in the morning and at night, because the inverter is trying to limit power generation conditions. If it occurs under normal sunlight, the detection method is still the elimination method, and the detection method is the same as Item 1. （3） Leakage current fault If the leakage current is large, remove the input terminal of the photovoltaic array, and then check the external AC power grid. When all DC and AC terminals are disconnected, the inverter will be powered off for 30 minutes. If it can be restored, please continue to use it. If it cannot be recovered, please continue to use.
