Why is inverter marked with “surge power”?

Surge power is related to the demand for instantaneous high power when using electrical appliances. When you use an inverter, if you encounter a situation where you need to start a device with a motor, surge power can come into play.

What does surge power do?

First, we need to clarify the definition of surge power: surge power usually refers to the power required for a short period of time when a device is started, which is higher than the rated power of the device itself. For example, devices with motors, such as motors and compressors, have a large instantaneous current when starting, which may require several times the rated power. At this time, if the inverter can only provide rated power, it may not be able to start these devices, resulting in tripping or damage.

Why can the inverter support this surge?

In the circuit structure of the inverter, there may be capacitors or inductors to store energy and release it when needed to deal with surges. For example, capacitors are charged during normal times and discharged quickly when the device starts, providing additional current. This involves the design of the inverter, such as larger capacitors or more robust power components.Inverters are usually designed with overload protection mechanisms, and inverters that can support overload for a short period of time and have surge capabilities require a certain level of technology. VOLTWORKS inverter has a great technical advantage and can provide a two-second surge.

What application scenarios require surge power?

For example, in a home solar system, the inverter needs to drive the refrigerator, air conditioner, etc. These appliances have compressors inside, and a surge is required when they are started. And when you are working outdoors, using water pumps, power tools, etc. If the inverter does not have sufficient surge capacity, the system inside will be unstable and even damage the equipment.If you consistently have trouble starting your unit, there’s a good chance that your inverter doesn’t have enough surge capacity. While VOLTWORKS inverter has such surge capability. It’s very suitable for high-power inductive loads, such as air conditioning, double door refrigerators, water pumps, heaters, and other electric tools.

In general, the purpose of the inverter supporting surge power is to cope with the short-term high power demand generated by certain electrical equipment during startup or instantaneous load changes.
