WZRELB Modified Sine Wave Inverter

1500 Watt 12V/24V Auto-Detected Modified Sine Wave Inverter

• 12V/24V Auto-Detected Input: This inverter automatically detects 12VDC or 24VDC battery input, making installation easier and reducing wiring mistakes. It delivers stable 1500W continuous modified sine wave AC power with 3000W surge power for mobile, backup, and everyday off-grid applications.
  
• Cost-Effective Modified Sine Wave Output: Provides reliable AC power for many common loads such as lights, fans, simple tools, chargers, TVs, and other standard appliances. It is a practical solution for general-purpose battery power applications.
  
• LED Status Display: Equipped with a clear display for basic real-time monitoring, helping you check operating condition and system status during use.
  
• Intelligent Cooling System: Built with temperature-controlled cooling and durable housing for effective heat dissipation, helping the inverter remain stable during long-time operation.
  
• Comprehensive Protection: Built-in protections include overcurrent protection, overvoltage protection, undervoltage protection, overload protection, short circuit protection, over temperature protection, and reverse polarity protection for safer operation.
  
• Practical for Mobile and Field Use: Suitable for trucks, vans, RVs, worksites, emergency backup, and outdoor power use where dependable modified sine wave output is needed from 12V or 24V battery systems.
  
• Note: Modified sine wave inverters are suitable for many common appliances, but they are not ideal for some sensitive electronics, precision equipment, or certain appliances with high startup requirements.

Attentions for resistive load applications:

If you need the inverter to run resistive loads such as lights, simple heaters, fans, chargers, and common appliances, please choose the inverter with continuous power higher than the appliance's rated power. For this 1500W inverter, it is better to use about 70% to 80% of the rated power for long-time operation.

Attentions for inductive load applications:

If you use refrigerators, pumps, air compressors, air conditioners and other appliances with motors or compressors, please choose the inverter carefully because startup surge power is much higher than running power. For these loads, a higher power inverter is usually required.

Warranty: 1 Year limited warranty.

Choose your Spec from the size options. Please confirm your required AC output voltage and frequency when ordering.

This inverter automatically detects only the DC input voltage between 12VDC and 24VDC. There is no auto-sense of the AC output voltage or frequency. Please confirm your needed AC output voltage and frequency when ordering.

Note: Modified sine wave inverters are more suitable for general-purpose loads than highly sensitive electronic equipment.

Do not connect the inverter directly to the utility grid, and do not use it in a sealed space without ventilation.

1. How does the 12V/24V auto-detected function work?

The inverter automatically identifies whether the connected battery system is 12VDC or 24VDC at startup, making installation easier and reducing input voltage mismatch.

2. What kind of appliances is this modified sine wave inverter suitable for?

It is suitable for many common loads such as lights, fans, chargers, simple tools, pumps, and general appliances. It is not the best choice for some highly sensitive electronics or precision equipment.

3. Why does the inverter shut down when running loads?

Common reasons include overload, low battery voltage, high battery voltage, poor cable connection, or over temperature protection. Please check the battery condition, cable size, cable connection, and ventilation around the inverter.

4. Can I run refrigerators or compressors with it?

Some inductive loads may require much higher startup surge power than their running power. Please allow enough surge margin when selecting the inverter.

5. Can I use it for long-time operation?

Yes. For better durability and thermal performance, it is recommended to use about 70% to 80% of the rated power during extended operation.
