2. Safety Instructions
Always observe the following safety precautions to prevent injury or damage to the inverter and connected devices:
- Do not open the inverter casing. High voltage is present inside.
- Ensure proper ventilation. Do not block ventilation openings.
- Keep away from water and moisture. This inverter is not waterproof.
- Avoid flammable materials. Do not operate near gasoline, propane, or other flammable liquids or gases.
- Connect to a 36V DC power source only. Connecting to other voltages will damage the inverter.
- Do not exceed the rated output power of 1800W. Overloading can cause damage or fire.
- Ensure correct polarity. Reverse polarity connection will cause immediate damage.
- Ground the inverter properly. Follow local electrical codes.

5. Setup and Installation
Follow these steps for safe and correct installation:
- Choose a suitable location: Install the inverter in a dry, well-ventilated area, away from direct sunlight, heat sources, and flammable materials. Ensure adequate space around the inverter for air circulation.
- Prepare the battery: Ensure your battery system is 36V DC. Turn off all loads connected to the battery.
- Connect Negative Cable: Connect the negative (-) cable from your 36V battery bank (in parallel or series configuration) to the negative (-) terminal on the inverter. Tighten securely.
- Spark-Proof Screw Contact (for safety): Briefly contact the positive (+) battery terminal with the spark-proof screw on the inverter's positive (+) terminal for 3-5 seconds. This pre-charges the inverter's capacitors and prevents sparks during final connection.
- Connect Positive Cable: Connect the positive (+) cable from your 36V battery bank to the positive (+) terminal on the inverter. Tighten securely.
- Grounding: Connect the inverter's grounding terminal to a proper earth ground.
- Verify Connections: Double-check all connections for tightness and correct polarity.

6. Operating Instructions
To operate your WZRELB inverter:
- Power On: After ensuring all connections are secure, press the ON/OFF switch on the inverter. The LED display will illuminate, showing the input DC voltage.
- Connect Appliances: Plug your AC appliances into the inverter's AC outlets. Ensure the total wattage of all connected appliances does not exceed 1800W.
- Monitor Display: The LED display shows the current input voltage. Monitor this to ensure your battery voltage remains within a safe operating range.
- Soft Start Feature: The inverter incorporates a soft start design, which gradually increases AC voltage upon startup. This reduces inrush current, protecting both the inverter and your connected appliances.
- Power Off: When finished, first turn off all connected AC appliances, then press the ON/OFF switch on the inverter to power it down.

7. Maintenance
Regular maintenance ensures optimal performance and longevity of your inverter:
- Keep Clean: Periodically clean the exterior of the inverter with a dry, soft cloth. Ensure ventilation openings are free from dust and debris.
- Check Connections: Regularly inspect all DC input and AC output connections for tightness. Loose connections can cause overheating and power loss.
- Battery Maintenance: Ensure your 36V battery bank is properly maintained and charged according to its manufacturer's recommendations.
- Storage: If storing the inverter for an extended period, disconnect it from the battery and store it in a cool, dry place.
8. Troubleshooting
Refer to the table below for common issues and their solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| No AC output, LED display off | Inverter not powered on; No DC input; Loose battery connections | Press power switch; Check battery voltage; Tighten DC cables |
| No AC output, LED display shows low voltage | Battery voltage too low | Recharge or replace battery |
| Inverter shuts down, LED display shows high voltage | Input voltage too high | Verify battery system is 36V; Disconnect from charging source if overcharging |
| Inverter shuts down, LED display shows overload | Connected load exceeds 1800W | Reduce connected load; Use appliances within inverter's rated power |
| Inverter shuts down, LED display shows over-temperature | Poor ventilation; High ambient temperature; Overload | Improve ventilation; Move to cooler environment; Reduce load |
| Fan runs constantly or loudly | High internal temperature; Dust in fan | Ensure proper ventilation; Clean fan vents; Reduce load |
