2. Safety Information
Observe the following safety precautions to prevent injury or damage to the inverter and connected devices:
- DO NOT exceed the inverter's rated power of 2000 Watts. Overloading can cause damage to the inverter and connected appliances.
- DO NOT leave the power inverter in the ON position while your vehicle's engine is off to prevent battery drain.
- Always disconnect the positive battery terminal before performing any wiring or maintenance on the inverter.
- Install the inverter in a cool, dry environment, away from direct sunlight, moisture, and flammable materials.
- Ensure proper ventilation around the inverter to prevent overheating. Do not block cooling fan vents.
- This inverter is designed for 12V DC input. Connecting to other voltage sources may cause severe damage.
3. Setup and Installation
3.1 Connecting to a Battery
- Ensure the inverter's power switch is in the OFF position.
- Connect the red battery cable to the positive (+) terminal of your 12V battery.
- Connect the other end of the red battery cable to the positive (+) input terminal on the inverter.
- Connect the black battery cable to the negative (-) terminal of your 12V battery.
- Connect the other end of the black battery cable to the negative (-) input terminal on the inverter.
- Ensure all connections are tight and secure.
- Connect the included earth wire to the ground terminal on the inverter and to a suitable ground point.
Note: For optimal performance and safety, use a 12V battery with a capacity of 400 Ah or above. Always use the provided cables or cables of equivalent gauge suitable for 2000W applications.
3.2 Remote Controller Installation
The remote controller allows for convenient monitoring and control of the inverter from a distance.
- Locate the RJ10 port on the inverter.
- Connect one end of the 15ft remote controller cable to the RJ10 port on the inverter.
- Connect the other end of the cable to the remote controller unit.
The inverter can also be turned on/off using the power switch directly on the unit if the remote controller is not connected or desired.

4. Operation
4.1 Powering On the Inverter
- After ensuring all connections are secure, switch the inverter's power button to the ON position.
- The LCD display on the inverter (or remote controller) will illuminate, showing input voltage, output wattage, and battery status.
4.2 Connecting AC Devices
The LEESKY 2000W inverter provides clean, stable pure sine wave electricity, suitable for sensitive electronics.
- Plug your AC devices into the two 110-120V AC GFCI outlets.
- For charging USB devices, use the two 2.4A USB ports.
- Ensure the total wattage of all connected devices does not exceed 2000W.

4.3 LCD Display and Remote Control
The LCD display provides critical operational data:
- Input Voltage: Displays the current DC voltage from the battery.
- Output Wattage: Shows the real-time power consumption of connected AC devices.
- Battery Status: Indicates the battery charge level.
- Protection Code: Displays error codes if a protection mechanism is triggered.
- Temperature: Shows the internal temperature of the inverter.
The remote controller mirrors this information and allows for convenient power control. It also features a backlight switch for visibility in various lighting conditions.

5. Protection Features and Troubleshooting
The LEESKY 2000W inverter incorporates multiple protection mechanisms to ensure safe operation and prevent damage to the unit and connected devices. The LCD display will show warning symbols and protection codes when an issue occurs.
5.1 Built-in Protections:
- Overload Protection: Activates when output power exceeds 2000W-2200W. The inverter will shut down to prevent damage.
- Over-temperature Protection: Engages if the internal temperature reaches approximately 149℉ (65℃). The intelligent cooling fan runs automatically when the temperature reaches 104℉ (40℃) or load power exceeds 40% of rated power.
- Low-input Voltage Protection: Triggers an alarm at 9.8V±0.5VDC and shuts down at 9.5V±0.5VDC to protect the battery from over-discharge.
- High-input Voltage Protection: Shuts down the inverter if input voltage exceeds 16V±0.5VDC.
- Short-circuit Protection: Automatically protects against output short circuits.
- Reverse Polarity Protection: Prevents damage from incorrect battery terminal connections.
- Input/Output Isolated Design: Enhances safety by electrically separating input and output circuits.

5.2 Troubleshooting Common Issues:
| Problem | Possible Cause | Solution |
|---|---|---|
| Inverter does not turn on. | Loose battery connections, low battery voltage, inverter switch off. | Check battery connections, charge battery, ensure inverter switch is ON. |
| No AC output. | Overload, short circuit, high/low input voltage, GFCI tripped. | Reduce load, check for short circuits, verify battery voltage, reset GFCI. |
| Inverter shuts down. | Overload, overheating, low/high input voltage. | Reduce load, allow inverter to cool, check battery voltage. |
| Fan runs constantly or loudly. | High internal temperature, heavy load. | Ensure adequate ventilation, reduce load. This is normal operation under certain conditions. |
6. Maintenance
Regular maintenance ensures the longevity and reliable performance of your LEESKY inverter.
- Cleaning: Periodically clean the exterior of the inverter with a dry, soft cloth. Do not use liquid cleaners or solvents.
- Ventilation: Ensure the cooling vents are free from dust and debris. Blocked vents can lead to overheating.
- Connections: Regularly check all battery and output connections to ensure they are tight and free from corrosion.
- Storage: If storing the inverter for an extended period, disconnect it from the battery and store it in a cool, dry place.
