How to choose pure sine wave inverter for car

Power selection

For ordinary family cars, it is enough to buy an inverter with a maximum power limit below 200W. According to Jiangyin Synovi , the insurance used by the 12V power supply of most household cars is less than or equal to 20A, and the maximum allowable electrical appliances are about 230W. For some older models, the maximum current allowed by the insurance is only 10A, so choose and buy The on-board inverter cannot only covet high power and choose the optimum one with the appropriate power. For some outdoor workers, those who need to use high-power electrical appliances can purchase an inverter directly connected to the battery. This inverter can be used for 500W or higher electrical appliances, and can drive small motors and some photographic soft boxes of 1000W.

Output interface

After the power is selected, it is necessary to look at the output interface of the inverter itself. At present, many electrical appliances use three-pin plugs, which requires a three-hole interface on the inverter. In addition, the USB interface is also useful, so it is best to choose an inverter with three interfaces.


Output waveform

According to the different output current waveform, the vehicle inverter is divided into pure sine wave inverter and modified sine wave inverter. Among them, the pure sine wave inverter has stable power supply and can basically drive common electrical appliances well, but the price is higher, and the quality of the 220V AC output by some high-end inverters is even higher than that of daily electricity. The modified sine wave is actually closer to the square wave, and the quality of the output current is poor, but the stability can be guaranteed in most cases, which is suitable for ordinary consumers to buy.

Protection function

Jiangyin Synovi recommends that when purchasing a vehicle inverter, be sure to confirm whether it has functions such as overvoltage shutdown, undervoltage shutdown, overtemperature protection, overcurrent protection and short circuit protection. These functions can not only affect the inverter itself Provide protection, and more importantly, avoid damage to electrical equipment.
