Overview

Built with advanced protection systems, this 48V 400W pure sine wave inverter prevents over voltage, low voltage, overload, short circuit, and over temperature. The aluminum alloy housing enhances heat dissipation and durability, while the quiet cooling fan keeps the unit running efficiently. Whether you're camping, traveling, or preparing for a power outage, this pure sine inverter provides reliable and quiet performance to keep your essential devices powered at all times.

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

How safe is a 48V pure sine wave inverter for indoor use?

A 48V pure sine wave inverter is generally considered safe for indoor use when proper precautions are taken. Pure sine wave inverters produce clean, stable AC power, making them suitable for sensitive electronics like computers, televisions, and medical devices. The primary safety concern with any inverter is electrical hazards, particularly the risk of short circuits, overloading, or improper wiring. Additionally, it is important to ensure that the inverter is connected to a well-ventilated area, as inverters can generate heat during operation. Maintaining clear airflow around the device prevents overheating. Many modern 48 volt pure sine wave inverters also come with built-in protections such as over-voltage, under-voltage, over-temperature, and short-circuit protection, enhancing the safety of indoor use.
