The inverter is a device that converts DC power into AC power (generally 220V, 50Hz sine wave). It is the opposite of a rectifier, which converts AC electrical energy into DC electrical energy. Inverter consists of inverter bridge, control unit and filter circuit. It is widely used in air conditioners, power tools, computers, TVs, washing machines, refrigerators,, massagers and other electrical appliances.
Inverter in the selection and use must pay attention to the following points:
1) DC voltage must match;
Each inverter has a nominal voltage, such as 12V, 24V, etc.
Requirement to select the battery voltage must be the same as the nominal DC input voltage of the inverter. Such as 12V inverter must choose 12V battery.
2) The output power of the inverter must be greater than the maximum power of the electrical appliances;
especially for some devices with large start-up energy demand, such as motors, air conditioners, etc., additional power margins are required.
3) Positive and negative poles must be wired correctly
The DC voltage connected to the inverter is labeled with positive and negative poles. Generally red for positive (+), black for negative (-), the battery is also labeled positive and negative, red for positive (+), black for negative (-), the connection must be positive to positive (red to red), negative to negative (black to black). The diameter of the connecting wire must be thick enough, and the length of the connecting wire should be minimized as much as possible.
4) The charging process and the inverter process can not be carried out at the same time, in order to avoid damage to the equipment, resulting in failure.
5) The inverter shell should be properly grounded to avoid personal injury due to leakage.
6) To avoid electric shock injury, non-professionals are strictly prohibited from disassembling, repairing, or modifying the inverter.
