5. Setup Instructions
Follow these steps to set up your sump pump battery backup system:
- Choose a Location: Select a dry, well-ventilated area near your sump pump and a 120V AC outlet. Ensure there is at least 2 inches of clear space around the inverter for proper cooling.
- Connect the Battery:
- Ensure the inverter's power switch is in the 'OFF' position.
- Connect the red battery cable to the positive (+) terminal of your 12V deep cycle battery and the positive (+) terminal on the inverter.
- Connect the black battery cable to the negative (-) terminal of your 12V deep cycle battery and the negative (-) terminal on the inverter.
- Ensure all connections are tight and secure.
- Connect the Sump Pump: Plug your primary sump pump(s) into the AC outlets on the front of the inverter. The inverter can power two primary sump pumps simultaneously.
- Connect to AC Power: Plug the inverter's AC power cord into a standard 120V AC wall outlet. The inverter will begin charging the connected battery.
- Power On: Flip the power switch on the inverter to the 'ON' position. The LCD display will illuminate, showing the system status.

6. Operating Instructions
Once properly set up, the SOLAR SPORTS 1500W Sump Pump Battery Backup Inverter operates largely automatically.
- Normal Operation: When AC power is available, the inverter will pass through AC power to the connected sump pump(s) and simultaneously charge the backup battery. The LCD display will show charging status and current AC output.
- Power Outage: In the event of an AC power failure, the inverter will automatically and instantly switch to battery power, providing continuous electricity to your sump pump(s). The LCD display will indicate battery discharge and DC voltage.
- Power Restoration: When AC power is restored, the inverter will automatically switch back to AC power and resume charging the battery.
- LCD Display: Monitor the LCD display for information on input/output voltage, frequency, and battery charge level. A green indicator light signifies normal operation, while a red fault indicator signals an issue.
- USB Port: The USB port can be used to charge compatible devices during normal operation or during a power outage.

7. Maintenance
Regular maintenance ensures the longevity and reliability of your inverter system.
- Keep Vents Clear: Periodically check that the cooling fan vents are free from dust and obstructions. Proper airflow is crucial for preventing overheating.
- Battery Care: The inverter's built-in charger maintains a 'trickle charge' to keep the battery fully powered. However, it is recommended to periodically check the battery terminals for corrosion and ensure they are clean and tight.
- Regular Testing: Test the system monthly by temporarily unplugging the inverter from the AC wall outlet to simulate a power outage. Verify that the sump pump operates correctly on battery power. Reconnect to AC power after testing.
- Cleaning: Clean the exterior of the inverter with a dry, soft cloth. Do not use liquid cleaners or solvents.

8. Troubleshooting
If you encounter issues with your inverter, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Inverter does not power on / No output | Loose battery connections, discharged battery, inverter switch off, internal fault. | Check battery cable connections. Ensure battery is charged. Turn inverter switch ON. If problem persists, contact support. |
| Red fault indicator is lit | Overload, short circuit, over-voltage, under-voltage, over-temperature. | Reduce load. Check for short circuits in connected devices. Verify battery voltage. Ensure proper ventilation. Turn off and restart the inverter. |
| Sump pump does not run during power outage | Battery not charged, faulty sump pump, inverter not switching. | Ensure battery is fully charged. Test sump pump directly with AC power. Verify inverter is ON and functioning. |
| Fans are noisy and run continuously | Normal operation, high ambient temperature, heavy load. | The fans are designed to run to maintain optimal temperature. Ensure adequate ventilation. This is often normal behavior. |
If troubleshooting steps do not resolve the issue, please contact SOLAR SPORTS customer support.
