WZRELB Pure Sine Wave Inverter
1800 Watt Pure Sine Wave Inverter with Wireless Remote - 24V
- PURE SINE WAVE POWER: Provides 1800W continuous power and 3600W peak surge power, delivering clean 120VAC / 60Hz electricity for appliances, electronics, tools, RVs, vehicles, backup power, and off-grid use.
- WIRELESS REMOTE CONTROL: RC version supports wireless on/off control for easier daily operation. Remote range is about 100ft indoors with walls and doors or 150ft in open area. Battery is not included; 23A 12V alkaline battery is recommended.
- LED DISPLAY & SOFT START: Digital LED display helps monitor input voltage at a glance, while soft start technology supports smoother startup and helps reduce inrush impact on connected appliances.
- MULTIPLE PROTECTION FEATURES: Built-in low voltage alarm, low voltage shutdown, over voltage shutdown, overload protection, and over heat protection help improve operating safety and protect connected equipment.
- DURABLE ALUMINUM DESIGN: Compact aluminum housing supports heat dissipation and durability for mobile, vehicle, backup, and off-grid applications. Please choose the correct DC input voltage version before use.







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.
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.

- 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.
1800W 24V version: recommend a 90Amp fuse (1800W÷20VDC=90Amp)
- 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.
- 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.
- 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.
- 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.
