Overview

Lowest price 24V 500 watt pure sine inverter with USB output port, light weight, AC output can select 240V, 220V, 110V, 230V, 100V, 50/60Hz frequency. Device powered by pure sine wave power inverter is less likely to experience interference, overheating, or damage compared to those powered by modified sine wave inverter.

Note: If the load is a refrigerator or similar to a refrigerator with a compressor, it is recommended that the power of the inverter is more than 10 times the power of the load.

Features:

Intelligent integrated circuit control. Unique front and rear dual soft start technology, CPU core, SPWM pulse width control technology, special constant power technology, anti-reverse diode technology.
Pure sine wave. 100% pure sine wave output, low distortion, waveform and main power line AC waveform are basically the same, equipment accuracy is small, low interference, low noise, strong load capacity, can meet any type of AC load, without damaging the load.
Imported parts. The pure sine wave inverter materials are imported components, and the panel uses double-sided circuit boards to ensure high quality and high performance of the products, and to match the excellent quality of the detailed molds.
Working instructions intuitive working state. When the sine wave inverter undervoltage/overvoltage, overload, overtemperature, short circuit, the LED indicator lights.
Fault warning/buzzer alarm reminder. When the inverter high voltage, low voltage, over temperature, overload protection function is turned on, once the protection of the inverter is triggered, the inverter disconnects the power supply and the load enters the protection mode for the first time, and issues an alarm through the buzzer alarm device. Make your use more secure.

FAQ

What are the types of pure sine wave inverters?

In the realm of inverters, there are two primary categories: pure sine wave inverters and modified sine wave (often referred to as square wave) inverters. Here's a detailed comparison:

Pure Sine Wave Inverters: Pure sine wave inverters produce a clean, smooth, and consistent sinusoidal current (AC), closely replicating the power from the grid. These inverters do not introduce electromagnetic interference, ensuring stable and interference-free operation of sensitive electronics. Ideal for all types of loads, including sensitive electronics, medical equipment, and inductive loads such as refrigerators and air conditioners. Provides superior performance and reliability, maintaining the integrity and lifespan of the connected devices.
Modified Sine Wave (Square Wave) Inverters: Modified sine wave inverters produce a waveform that approximates a sine wave but is not smooth, resulting in a less consistent power supply. These inverters can introduce electromagnetic interference, potentially affecting the performance of sensitive devices. Not suitable for all types of loads, particularly sensitive electronics and inductive loads. Their load capacity is typically between 40-60% of the rated load. The abrupt transition from positive to negative maximum values can cause instability and inefficiency. High harmonic distortion can lead to increased capacitive currents, potentially damaging load filter capacitors and other components in connected devices.

When choosing an inverter, consider the specific requirements of your devices. For sensitive and high-demand applications, pure sine wave inverters are recommended. For less demanding applications, a modified sine wave inverter might suffice.

Responded by inverter.com

When the 24V 500W pure sine wave inverter is not in use, it is best to cut off its input power and do not place the inverter in the sun or near the outlet of the heater.
