Inverter is a kind of equipment that converts direct current (DC) into alternating current (AC). Most electrical appliances use alternating current. Inverter allows you to power standard appliances directly from batteries or battery packs without using standard wall socket plugs. The purpose of this article is to help you find the most suitable inverter for your power needs.
You need to determine why you provide energy, and have a clear object. Because inverter wholesale on the market now has more than one plug, and some even have multiple USB ports, which can charge mobile phones and tablets. Therefore, it is very important to use inverters for which objects and whether to use multiple inverters at the same time.
You need to confirm the total power wattage required by the items used by the inverter. This specification information can usually be found on the product-related label, which should be on the product itself or the transformer. If you can't find this information, I suggest you visit the manufacturer's website of this product to see if this information is published in the general description or specification PDF of the product. Getting the correct wattage information will save you time, avoid possible troubles, and avoid the situation that the wattage does not meet the specification when purchasing other equipment in the future.
And surge power is the power used to start the equipment. For example, suppose you have a coffee machine that requires 300 watts of continuous power. When you turn on the coffee machine for the first time, it will probably consume at least twice the rated power consumption (600 watts) in a few seconds, and then reduce its power demand to the prescribed 300 watts. In most inverter descriptions and advertisements, surge power is usually shown as "peak power", and in most cases it is twice the normal output power of the inverter. When looking for a suitable inverter, you can use your total conventional power consumption and surge consumption as a reference point to compare different inverter models.
Pure sine wave:
Common items that require pure sine waves are medical equipment, oxygen concentrators, sleep ventilators, fax machines, high-resolution televisions and equipment with variable-speed motors.
Corrected sine wave:
Common items that use corrected sine waves are small household appliances, such as notebook computers, mobile phones, electric blankets, personal computers, coffee machines, most stereos, inkjet printers, refrigerators, most televisions and microwave ovens.
