Overview

Affordable price 24 volt 300 watt pure sine wave inverter for home use, high efficiency, compact design, lightweight, output frequency 50Hz or 60Hz can be selected, AC output 110V, 120V, 220V, 230V and 240V are optional. This capacity of true sine wave inverter is suitable for running various small electronic devices, appliances, or tools with a combined power consumption not exceeding 300 watt.

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 powerful should a pure sine wave inverter be to drive 300W household appliances?

To drive 300W household appliances, you must use a true sine wave inverter with a power rating exceeding 300W. It is advisable to choose an inverter with a higher power rating, such as 500W, to ensure reliable performance and account for any potential surges in power demand. The key considerations are as follows:

Inverter Power Rating: Ensure the inverter's continuous power rating is higher than the total power consumption of all connected appliances. Account for the peak power ratings of individual appliances, especially those with motors or compressors, which may have significantly more power at startup.
Input Voltage: Common input voltages for inverters include 12V, 24V, 36V, and 48V. Select the appropriate input voltage based on your power source and system configuration.
Output Voltage and Waveform Quality: Ensure the inverter provides a stable and high-quality output waveform. Pure sine wave inverters offer the best compatibility and efficiency for sensitive electronics and household appliances.
Conversion Efficiency: Look for inverters with high conversion efficiency to maximize the effective use of your power source and minimize energy loss during the inversion process.
Compatibility and Load Management: Sum the power requirements of all appliances you intend to power simultaneously to ensure the total load does not exceed the continuous power rating of the inverter. Consider the peak or surge power requirements of appliances, particularly those that may have higher startup power demands.

By carefully selecting an inverter with appropriate power ratings and considering the factors mentioned above, you can ensure the safe and efficient operation of your household appliances.

300w pure sine wave inverter does a good job

This pure sine wave inverter does a good job for the ability to power my refrigerator. Easy to connect, robust, and very quiet. We have connected electronic devices to the inverter and they have all worked perfectly. It is a good choice to use this as a generator for power outages.
