WZRELB Pure Sine Wave Inverter

1000 Watt WZRELB Pure Sine Wave Inverter

• High-Quality Pure Sine Wave Inverter: Equipped with premium filtering design and stable pure sine wave output technology, this inverter delivers 1000W continuous power and 2000W peak surge power. It supports DC input versions including 12v / 24v / 36v / 48v and is configured for 120VAC output at 60Hz, providing clean and reliable AC power for small RV systems, TVs, laptops, chargers, lighting, and light backup applications.
  
• Intuitive LED Display: Equipped with a clear digital LED display, this inverter allows you to monitor the input voltage in real time, helping you understand operating status more easily during travel, backup use, and off-grid applications.
  
• Soft Starter Technology: Designed with a built-in soft starter, this inverter supports a smoother rise of AC voltage at startup. This helps reduce inrush impact on connected appliances and improves operating stability.
  
• Compact and Durable Design: Measuring approximately 10.2 x 3.8 x 2.5 inches and weighing about 2.86 lbs, this inverter is designed for mobile and off-grid use. The all-aluminum shell helps improve heat dissipation and durability during operation.
  
• Practical Daily Use: This standard version is suitable for users who want a straightforward inverter setup for RV systems, backup power, off-grid use, and vehicle-based electrical applications without extra remote-control accessories.
  
• Note: Due to the high operating temperatures under heavy load, avoid touching the inverter housing while in use.
  

Attentions for resistive load applications:

If you need the inverter to run resistive loads such as laptops, TVs, electric cookers, lights, routers, and chargers, please choose an inverter with continuous power higher than the appliance's rated power. It is better to use about 80% of the rated power for daily operation and longer product life.

Attentions for inductive load applications:

If you use refrigerators, freezers, microwaves, water pumps, air conditioners and other appliances with compressors or motors, please choose the inverter whose continuous power is 3-7 times higher than your appliance's working power. Some compressor loads may require even higher startup margin.

Warranty: 12 Months for Non-artificial damage.

Choose your spec from the size options. Please confirm your battery voltage(  12v / 24v / 36v / 48v  ) before ordering.

This version is fixed at 120VAC output and 60Hz frequency. Please leave your message about the socket type you need when ordering.

Note: This inverter does not auto-sense input voltage. Please choose the correct battery system version before ordering.

Output specification for this version: 120VAC / 60Hz.

 

1. Can I add a fuse or circuit breaker between the input terminal of the inverter and the battery? If so, what specifications are recommended?

Yes, the following is the calculation of fuse ampere.

Continuous power of the inverter ÷ Lowest input voltage = Fuse ampere, e.g.

 1000W 12V version: recommend a 100Amp fuse (1000W÷10VDC=100Amp)

 1000W 24V version: recommend a 50Amp fuse (1000W÷20VDC=50Amp)

 1000W 36V version: recommend a 34Amp fuse (1000W÷30VDC=34Amp)

 1000W 48V version: recommend a 25Amp fuse (1000W÷40VDC=25Amp)

2. Why did sparks appear on the cable and the inverter terminal when connecting the battery to the inverter?

This is normal, and it does not mean the inverter is malfunctioning. The inverter has built-in capacitors, so when the battery cable is connected to the inverter input, a small spark may appear as part of the charging process.

3. Why does the inverter's output voltage keep dropping or even shut down automatically when running loads?

First, check whether the fuse or breaker size is correct. Second, make sure the battery cables are thick enough and all supplied cables are used correctly. Third, check whether the battery capacity is too small for the load. Thin cables, long cable runs, or weak battery systems can all cause voltage drop.

4. Why can't the inverter be turned on?

Please fully charge the battery before installing the inverter. When battery power is too low, the inverter may enter low-voltage protection or fail to start.

5. Why can't my inverter run the refrigerator?

Refrigerators use compressors, which are inductive loads and can require a startup surge many times higher than their running power. In many cases, you need an inverter with much higher surge margin than the refrigerator's working wattage.
