5. Operating Instructions
5.1 Powering On/Off
- To power on the system, press and hold the power button until the LCD screen illuminates.
- To power off, press and hold the power button again until the LCD screen turns off.
5.2 Automatic Transfer Function
When connected to both AC power and a battery, the system operates in standby mode, charging the battery. In the event of a power outage, the system will automatically detect the loss of AC power and seamlessly switch to battery power, providing uninterrupted operation for your connected sump pump(s).
5.3 LCD Display Monitoring
The high-definition LCD display provides real-time information about the system's status:
- Input Voltage: Displays the incoming AC voltage.
- Output Voltage: Shows the AC output voltage supplied to the sump pumps.
- Power (Watts): Indicates the current power consumption of connected devices.
- Battery Level: Shows the remaining charge in the connected battery.
- Frequency: Displays the output frequency (e.g., 60Hz).
- Protection Indicators: Icons for Over Voltage (OV), Low Voltage (LV), Over Temperature (OT), Overload (OL), Short Circuit (SC), and Grid Input (GRD) will illuminate if a protection event occurs.

6. Maintenance
Regular maintenance ensures optimal performance and longevity of your battery backup system.
- Battery Inspection: Periodically check battery terminals for corrosion. Clean with a wire brush if necessary. Ensure battery fluid levels are adequate for flooded lead-acid batteries.
- System Cleaning: Keep the inverter's ventilation openings clear of dust and debris to prevent overheating. Use a dry cloth to wipe the exterior.
- Functionality Test: It is recommended to periodically test the system by simulating a power outage (e.g., by temporarily unplugging the AC input) to ensure the automatic transfer function is working correctly.
- Fuse Replacement: If a fuse blows, replace it with a fuse of the same rating (50A). Refer to the unit's labeling for fuse locations.
7. Troubleshooting
