1. Introduction
The WZRELB 2000W Pure Sine Wave Inverter is designed to convert 12V DC battery power into 120V AC household power at a 60Hz frequency. This device provides clean, stable power suitable for a wide range of electronic devices and appliances, making it ideal for off-grid systems, RVs, boats, and emergency power backup.
2. Safety Information
- Proper Ventilation: Ensure the inverter is installed in a well-ventilated area to prevent overheating. Avoid placing flammable materials near the unit.
- Correct Wiring Sequence: Always connect the positive (+) battery cable first, then the negative (-) battery cable. When disconnecting, remove the negative cable first.
- Sparking: It is normal to observe a small spark when connecting the negative battery cable. Ensure connections are secure and in a well-ventilated space.
- Cable Gauge: Use appropriate gauge cables for the power rating to prevent overheating and potential damage. The product includes standard battery cables.
- Avoid Continuous Loops: If integrating with an RV's existing electrical system, ensure the inverter's output does not feed back into the RV's built-in inverter/charger circuit to prevent a continuous loop. This typically involves switching off the circuit breaker for the built-in charger.
- Grounding: Ensure the inverter is properly grounded to prevent electrical hazards.
- Battery Capacity: For optimal performance and to avoid insufficient battery capacity issues, it is recommended to use a battery system of at least 210AH for a 2000W 12VDC inverter.
- Safety Gloves: Always wear safety gloves when handling batteries and making electrical connections.

5. Setup and Installation
Follow these steps for proper installation of your WZRELB 2000W Pure Sine Wave Inverter:
- Mounting: Securely mount the inverter in a well-ventilated area. The inverter features mounting brackets for easy installation.
- DC Connection: Connect the provided battery cables to the inverter's DC input terminals and your 12V battery. Ensure all four cables (two positive, two negative) are used for optimal performance, especially for the 2000W model. Always connect the red (positive) cable first, then the black (negative) cable. Tighten all connections securely. A small spark when connecting the negative cable is normal.
- Grounding: Connect the inverter to a proper earth ground using the designated grounding terminal.
- AC Output: The inverter features dual US standard AC outlets for connecting your appliances. For RV integration, an external plug can be used to connect the RV's main power cord to the inverter's output.
- Circuit Management (for RVs): If integrating with an RV's existing electrical system, ensure you disable or switch off the circuit breaker for the RV's built-in inverter/charger to prevent a continuous power loop.

6. Operating Instructions
Once properly installed, operating the WZRELB 2000W Inverter is straightforward:
- Power On: Use the power switch on the inverter's front panel to turn the unit on. The digital LED display will illuminate.
- Monitoring: The digital LED display provides real-time information on the DC input voltage (from your battery) and the AC output voltage.
- Connecting Appliances: Plug your 120V AC appliances into the dual US outlets. Ensure the total wattage of connected appliances does not exceed the inverter's continuous power rating of 2000W.
- Cooling Fan: The intelligent temperature-controlled cooling fan will activate automatically when needed to maintain optimal operating temperature.

7. Maintenance
Regular maintenance ensures the longevity and reliable operation of your inverter:
- Connection Checks: Periodically inspect all battery and output connections to ensure they remain tight and free from corrosion. Loose connections can lead to overheating and power loss.
- Ventilation: Keep the inverter's ventilation openings clear of dust and debris to ensure proper airflow for cooling.
- Fuse Replacement: The inverter is equipped with internal fuses for protection. If an overload occurs and the inverter stops functioning, check and replace any blown fuses with spare fuses provided or suitable replacements.
- Cleaning: Keep the exterior of the inverter clean and dry. Use a soft, dry cloth for cleaning.
8. Troubleshooting
If you encounter issues with your WZRELB 2000W Inverter, refer to the following common problems and solutions:
- No Power Output / Inverter Off:
- Check battery connections for tightness and corrosion.
- Verify battery voltage is within the operating range (10V-15V DC).
- Check for blown fuses and replace if necessary.
- Ensure the inverter is not in an overload or overheating protection state (check LED indicators).
- Voltage Fluctuations (e.g., 110V to 130V AC): While some minor fluctuation may occur, significant and unstable output voltage can indicate an issue. Ensure proper battery capacity and stable DC input.
- Inverter Shuts Down Without Load: Some inverters may shut down if there is no load or a very low load for an extended period. This can be a design feature. If this is problematic for specific appliances (e.g., refrigerators with cycling compressors), consider adding a small continuous load or using a different inverter model.
- Overheating: Ensure adequate ventilation around the inverter. Reduce the load if the inverter is consistently overheating. The intelligent cooling fan should activate to manage temperature.
- Low Voltage Alarm: This indicates the battery voltage has dropped below the low voltage alarm threshold (9.5V-10.5V). Recharge or replace the battery.
- Overload Warning: This indicates the connected load exceeds the inverter's capacity. Reduce the load immediately.
