Many High-power Inverters Choose 24V, Because A 24V Battery With The Same Capacity Provides A Larger Output Current Than A 12V Battery.

Aug 12, 2020

Many high-power inverters choose 24V, because a 24V battery with the same capacity provides a larger output current than a 12V battery.

The 12V voltage is very safe for household use and is not prone to accidents. However, the inverter efficiency is relatively low and the loss is large.

48V voltage, home safety is almost impossible, people may accidentally be electrocuted. However, the inverter efficiency is relatively high and the loss is small.

Inverters for households and cars generally do not exceed 5000W. Most of the inverters on the market are 12V and 24V.

In addition, 36, 48, 60 and other high input voltage inverters are suitable for connecting electric bicycle batteries or other special applications.

12V, 24V, 48V carefully read the delivery instructions, after comparison and actual measurement, whether it is 12V or 24V, under the same power, the output current and loss are almost the same. This is a relatively small power inverter (within 2000W). But many high-power inverters choose 24V, because a 24V battery with the same capacity provides a larger output current than a 12V battery.

Especially electrical appliances with air conditioners or high-power inductive loads require a large current output at the moment of startup. Below 2000W I suggest you choose 12V, so it is convenient to choose the battery. For inverters above 2000W, 24V inverters are recommended.

No matter what kind of inverter you choose, be sure to ask the store about their actual power (sustainable power). Many businesses use peak power to mark. For example, if the actual power is 1000W, some brands will mark it as 2500W, then you buy In fact, it can only drive 1000W electrical appliances. When the inverter is fully loaded, the conversion efficiency of 12V DC to 220V AC can only reach about 85%. Don’t believe the Internet, they say it can reach 95% or more. Up to 95% are high-power inverters only when there is no load. If you buy a 1000W pure sine wave inverter, as long as the power does not exceed 1000W, it is basically no problem. Similarly, if the 1000W is a square wave (modified sine wave) inverter, it will not There is a certain amount of trouble, and there will be noise with induced load. It is recommended to spend more money to buy a pure sine wave inverter. In this way, you can basically use it regardless of the electrical equipment, as long as the power is not higher than the inverter.
