What do I need to know before buying an inverter?

Have you encountered the following problems when choosing an inverter:

1. How to choose the inverter brand? 2. How to choose the inverter power, should I use high power or low power? 3. What should I do if the voltage is not enough? 4. Can the equipment run all day long? 5. Is the after-sale service good? Wait for a series of worries. Next, the editor of Baoweite will take you to choose the inverter power supply product that suits you normally. You don’t have to buy blindly anymore to understand this article.

Note for Xiaobai when choosing inverters:

Regardless of home, outdoor, vehicle-mounted inverters, single appliances: such as induction cookers, microwave ovens, washing machines, air conditioners and other equipment, you can choose 12/24V 300-3000w power. Most of the equipment is 110 or 220V current, so basically all electrical appliances need to provide energy through the inverter. Then this kind of household appliances can be satisfied by choosing a lower power. Please pay attention to the following points.

1. Confirm the power of your electrical appliances.

2.Determine its peak power.

3. Input voltage, current, frequency...

For 1 and 3 points, they are generally marked on electrical appliances. The most difficult to determine is the peak value, and this is the most important point to buy an inverter, because even if your inverter product has sufficient power, the peak value is not enough The same cannot be turned on.

What is peak power? Peak power refers to the power used by electrical appliances to turn on when you turn on the device. For example, a TV, an electric drill, you will hear a sound at the moment of turning on, and the phenomenon of voltage jumps is that the electrical appliance is turned on. The instantaneous impact phenomenon. Therefore, the peak power is different from the rated power. Generally speaking, resistive loads, such as light bulbs, do not have peak problems, but for inductive and capacitive electrical appliances, there are generally 3 It is 5 times the peak value. Therefore, we must pay attention to buying inverters, because inverters are double peak values. For example, TV sets have a nominal rated power of 75W, but the peak value is 5 times. Which peak value is 350W. In this way, you can't turn on a 100W inverter, because a 100W inverter has a peak value of 200W, so we have to use a 300W machine first, which has a peak value of 600W, and of course it can be turned on.

For the peak value of electrical appliances: bulbs, there is no peak value, 100W inverters can light up 100W bulbs, TVs, there are 3 to 5 times the peak value, 75W TVs, use more than 300W machine start, electric drill, 3 To double the peak value, computer monitors are generally 6 times or more. So it is still a bit difficult for a 300W machine to start. For a laptop computer, it is generally 70W, and a 150W inverter can start, because it is generally 3 times the peak value ( 210W peak value).For digital products such as mobile phone chargers and camcorders, a 100W inverter is generally sufficient.

In the market, there are many brands of inverters, but some are equivalent to the seller's OEM. In the OEM part, it is called high-power. Generally speaking, it calls 300W 500W. 500W is called 1000W, how do we determine it? Generally, we can determine it from its volume, weight, and peak value. Because the design principle of 99% of the inverters on the market is the same, so if the same kind of power is very small , The weight is very light, and the peak value is not enough, it can be said that it is called high-power selling.

Regarding the working time of the inverter, I mean how I can determine the working time of a battery when the load is set. Let me first explain the battery capacity, the battery is the standard capacity in ampere hour, unit: ampere hour (AH), ampere hour means: the maximum discharge capacity of the battery in one hour. For example, a battery is nominally 100AH, how can we say that it can continuously output a current of 100A in one hour. So, we can use This value is used to calculate the time it takes for a battery to drive a load.
