Overview

A 48V 500W pure sine wave inverter is a device used to convert DC (direct current) power from a 48-volt battery source into AC (alternating current) power with a clean and smooth sine wave output. Power inverter adopts with intelligent temperature control, output frequency 50Hz or 60Hz, low noise, easy to operate.

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.

Details:

Aluminium Alloy housing

Aluminium's excellent thermal conductivity facilitates efficient heat dissipation, enhancing the inverter's performance and lifespan. its corrosion resistance ensures longevity even in harsh environments. Thermal efficiency, and environmental friendliness, making it an optimal choice for sine wave power inverter.

Single Intellengent Cooling Fan

Optimize energy consumption by adjusting fan speed based on temperature, enhancing efficiency. Intelligent cooling fan in 48V pure sine wave inverter ensures quieter operation compared to traditional fan, enhancing user comfort. It contributes to environmental sustainability by reducing energy waste and emissions.

Screw Terminal

Screw terminals provide a secure and reliable connection, minimizing the risk of loose wiring and electrical faults. Their robust design ensures efficient power transfer, reducing energy loss and enhancing overall system performance. Screw terminals optimize the functionality and reliability of 500W pure sine power inverter.

FAQ

I want to buy an inverter for my refrigerator. What is the best inverter to buy?

When selecting an inverter for your refrigerator, it is essential to consider several factors such as reliability, efficiency, and compatibility. Here are some key points to help you make an informed decision:

Type of Inverter: Choose a pure sine wave inverter. This type of inverter provides clean and stable power, which is crucial for protecting your refrigerator's sensitive electronic components from potential damage caused by power fluctuations.
Power Capacity: Ensure the inverter has enough power capacity to handle the initial surge of your refrigerator. Refrigerators typically have a starting surge that is 2-3 times their running wattage. For a refrigerator with a running wattage of around 200W, you should look for an inverter with a minimum capacity of 500 watts to accommodate the higher starting current.
Efficiency and Reliability: Opt for inverters from reputable brands known for their efficiency and reliability. Check for customer reviews and ratings to gauge the performance and durability of the inverter.
Additional Features: Consider inverters with additional features such as overload protection, low battery alarm, and automatic shut-off. These features can enhance the safety and longevity of both the inverter and your refrigerator.

By taking these factors into account, you can choose an inverter that not only meets the power requirements of your refrigerator but also ensures its safe and efficient operation.
