Principle one: DC voltage to be consistent Each inverter will be marked with an access DC voltage value on its device, such as 12 volts, 24 volts, and so on. This requires people to have the option of the corresponding battery voltage when using it. In general, a 12-volt inverter must be fitted with a 12-volt battery. If the 12-volt inverter selects a 24-volt battery, it is possible to burn down the relevant parts of the inverter and reduce the cycle of its use.
Principle two: The output power must be higher than the electrical power used Inverter output power is greater than the use of electrical power, otherwise there will be a variety of use failures. In particular, many of the current household appliances need the power is very large. Also to ensure that the output power is greater than the use of electrical power, then can make the electrical appliances into a normal state of use, otherwise it will not be able to work because of insufficient power.
Principle three: Positive and negative poles must be correct and then Many people do not look at the positive and negative poles shown by the wires when connecting the wires of the inverter. In fact, this is not right, because as long as the answer to the positive and negative poles, then the inverter can work properly, otherwise it will not provide effective electrical energy, electrical products can not enter the work. When this happens, many people still think that the electrical products are broken and carry out various repairs. Therefore, when connecting the positive and negative electrode wires, it is important to distinguish them clearly from the positive and negative poles.
