A 220V inverter is a device that converts 12 or 24V direct current into 220V alternating current. This is the voltage used in the homes of Ukrainians.
Current inverters have some properties that affect their use and the price of the product. Main types of inverters:
- With an irregular sine wave - has a square sine shape - suitable mainly for devices that do not have a transformer and an electric motor.
- With an approximated sine wave - it has a square sine shape close to the correct one - it works better with transformers and power supplies, but it can make a noise similar to cracking, it also does not work for engines
- With a clean sinus - this is the best and safest option for pulling out - it has the correct shape of the sinus - the same as in the network - so it fits absolutely all equipment.
The operating voltage is 12V and 24V, depending on the type of battery, and 12V is the most popular, since everyone has such a battery from a car. But you need to understand that 12V power is more than 1000W, it is better not to use it because of the large current, about 100A, if you need 1000W or more, use 24V inverters.
The principle of operation of the inverter is as follows - we connect the battery to the terminals (carefully do not confuse the plus and minus wires, because this way the inverter will fail). Wires are selected depending on the power of the inverter:
- for 300 W - 4-6 mm copper,
- for 600 W - 6-12 mm copper,
- for 1000 W - 16-25 mm copper,
After connecting the battery, press the power button and wait for the inverter to turn on - it usually beeps after turning on. After that, you can connect the devices to the inverter and use them. But do not overload the inverter, as a rule, all inverters are equipped with overload protection - and will automatically turn off. Also, "plug-plug" cables are often used in order to power the whole house - you should be careful with such things, exclude the possibility of reverse current in the inverter so as not to burn it.
And most importantly, there are very often manufacturers who overestimate the power of their inverters by 3-4 times, that is, a 2600W inverter has a rated power of only 600-800W. Be careful when choosing such inverters because your equipment is more expensive and may fail due to the poor quality of the inverter.
