The sine wave inverter is an electric energy conversion device that converts direct current into alternating current. It completes the inverter task by turning on and off power semiconductor devices according to a specific law.
Modern inverter technology is a science that studies the theory and application of inverter circuit and design methods. It is based on industrial electronics technology, semiconductor device technology, modern control technology, modern power electronics technology, pulse width modulation technology, semiconductor converter technology and A practical technology based on science such as magnetic materials, so the application of sine wave inverters runs through the matching between the output characteristics of solar panels in many areas of society and life.
The first is the choice of inverter and power supply. For the use of a sine wave inverter, we must provide the corresponding power supply through a battery or some other equipment. For example, in daily life, we can also use a car cigarette lighter to power the sine wave inverter. Of course, the car cigarette lighter can only be connected to low-power devices. If the power is too large, the appliance cannot directly receive power through the inverter.
Generally, electrical appliances with a power of less than 300W can be connected to the cigarette lighter part of the car to get electricity. This type of inverter is usually called an on-board inverter. equipment. For electrical appliances with relatively high power, we need to use clamping wires. The thickness of the wire clamp is related to the power of the inverter. It is directly proportional to this relationship. The clamp wire is directly connected to the battery terminal to turn on the power. For different electrical appliances, we can use different models of pure sine wave inverters.
Pure sine wave inverters can drive induction appliances(pure sine wave inverter: off-grid inverter). When choosing an inverter, the power of the pure sine wave inverter should be slightly larger than the power of the appliance according to the power of the appliance, so that the inverter will not be overloaded. To ensure the normal use of inverters and electrical appliances. Induction devices such as refrigerators, air conditioners, pumps, etc. need pure sine wave inverters or power frequency inverters to drive.
The second step is to connect the inverter to our power supply; before proceeding, we must first confirm that the inverter and all machine switches are turned off, that is, they are all turned off. First, we need to connect the negative terminal of the battery to the negative terminal of the sine wave inverter. The positive terminal of the battery is connected to the positive terminal of the sine wave inverter, and then the electrical device is connected to the inverter, and then the inverter is turned on. With this switch, you can power the device.
