RBQ Series Pure Sine Wave Inverter

2000 Watt Pure Sine Wave Inverter

• True Pure Sine Wave Output: This RBQ series inverter converts DC power to clean AC power for household equipment with continuous 2000W output and surge power of 4000W. It supports 110VAC or 120VAC output and 50Hz or 60Hz frequency according to customer requirement, making it suitable for home backup, RV use, truck power, solar systems, and off-grid installations.
  
• USB and PD Charging Ports: Equipped with a 2.4A 5V USB port for phones and tablets, plus a 60W PD port, this inverter supports both AC appliance use and convenient charging for small digital devices.
  
• Low Interference and Low Idle Power Draw: Designed with low interference technology and low idle power consumption, it helps improve the performance of televisions, audio equipment, communication devices, and other sensitive loads while reducing unnecessary circuit loss.
  
• RS485 Communication Port: The inverter includes an RS485 port for communication with solar systems. If you need the communication protocol, customer service confirmation is required before use.
  
• Stable Cooling and Full Protection: Intelligent temperature-controlled dual cooling fans help maintain long-term stability. The inverter also includes over-voltage and under-voltage shut down, audible alarm and LED indicator for abnormal voltage, overload protection, short-circuit shut down, and over-temperature protection.
  
• Off-Grid and Emergency Use: This inverter is suitable for off-grid and emergency use with fully charged batteries. It can be used in solar and wind systems together with a solar charge controller, giving users a practical plug-and-play backup power solution.
  
• Compact Metal Housing: Machine size is approximately 30 x 22.5 x 8 cm and net weight is about 3.06 kg (6.7 lbs). The metal housing and dual-fan design support durability and heat dissipation during extended 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 the inverter with continuous power higher than the appliance's rated power. For daily use, it is better to use about 80% of the rated power for improved stability and longer service 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 the appliance's working power. Some motor loads may require even higher surge margin during startup.

Warranty: 12 Months for Non-artificial damage.

Choose your spec from the size options. Please confirm your battery voltage, AC output voltage (110VAC or 120VAC), and frequency (50Hz or 60Hz) before ordering.

This inverter does not auto-sense input or output voltage. Please choose one battery system version, one output voltage, and one frequency when ordering. If you need a specific socket type, please leave your message before shipment.

Note: This inverter is single-phase. Please confirm the exact output specification before ordering.

 

1. Can I add a fuse or circuit breaker between the input terminal of the inverter and the battery?

Yes. The common calculation method is: continuous power ÷ lowest input voltage = recommended fuse ampere. The exact fuse size still depends on the battery system version and cable design, so final confirmation before shipment is recommended.

2. Can this inverter work with a solar system?

Yes. This RBQ series inverter can be used in solar and wind systems together with a suitable solar charge controller and properly matched battery bank.

3. Why did sparks appear when connecting the battery cable?

This is usually normal. The inverter has internal capacitors, so a small spark may appear when the battery cable is first connected.

4. Why does the inverter shut down under load?

Please check whether the battery capacity is sufficient, whether the battery voltage is dropping too much under load, and whether the cable size and fuse size are correct. Long or thin cables can create noticeable voltage drop.

5. What is included in the package?

Standard packing includes:

1x 2000 W pure sine wave inverter,
1x fuse replacement,
1x battery cables,
1x manual.
