4. Operating Instructions
4.1 Front Panel Indicators
The front panel of the LG1100 Inverter features LED indicators to display its operational status:
- Mains ON: Indicates that the inverter is receiving power from the main utility supply.
- Charging: Indicates that the battery is currently being charged.
- UPS ON: Indicates that the inverter is operating in UPS mode, providing power to connected appliances.
- Inverter ON/Overload/Short Circuit: Indicates the inverter is active. If combined with an alarm, it may signal an overload or short circuit condition.
- Low Battery: Indicates that the battery charge is low and requires recharging.
- Eco Mode: Indicates that the inverter is operating in ECO mode.
- Power ON: General power indicator for the unit.
- Power ON/OFF Switch: Used to turn the inverter unit on or off.
4.2 Mode Selection (UPS/ECO)
The inverter features a switch on the rear panel for selecting between UPS and ECO modes:
- UPS Mode: Provides a stable output voltage, ideal for sensitive electronic devices like computers, laptops, and LED TVs, preventing data loss or damage during power fluctuations.
- ECO Mode: Offers a wider input voltage range, which can be more energy-efficient in areas with frequent voltage fluctuations, but may not be suitable for highly sensitive electronics.
4.3 Battery Type Selection
A 4-mode selector switch on the rear panel allows you to optimize charging for different battery types:
- Flat Plate: For flat plate batteries.
- Tubular: For tubular batteries.
- SMF (Sealed Maintenance Free): For SMF batteries.
- LOCAL: For locally manufactured batteries or other specific types.
Ensure the correct battery type is selected to maximize battery life and performance.
4.4 Load Capacity Guidelines
The LG1100 Inverter has a peak load capacity of 780W. Refer to the table below for typical appliance wattage and the number of units the inverter can support. Always ensure the total connected load does not exceed the inverter's capacity.
Figure 4.1: Appliance load capacity for various Livguard inverter models, including LG1100.
| Appliance | Power Rating (Watts) | LG1100 (900 VA) |
|---|---|---|
| LED Bulb | 10 | 3 |
| LED Tube Light | 20 | 1 |
| WiFi Router | 20 | 1 |
| LED TV | 75 | 1 |
| Laptop | 65 | 1 |
| Ceiling Fan | 80 | 3 |
| Room Cooler | 120 | 1 |
| Fridge | 200 | 1 |
Note: Backup time depends on battery Ah and condition. Load of appliances depends on Inverter VA. Square wave inverters can power water pumps when the total load of connected devices, including the water pump, is within the peak load of the Inverter.
5. Maintenance
The Livguard LG1100 Inverter is designed for low maintenance. However, regular checks can ensure optimal performance and longevity:
- Keep Clean: Ensure the inverter and battery area are clean and free from dust and debris.
- Ventilation: Ensure proper airflow around the inverter to prevent overheating. Do not block ventilation openings.
- Battery Terminals: Periodically check battery terminals for corrosion. Clean them if necessary and ensure they are securely tightened.
- Battery Water Level (for non-SMF batteries): If using a non-SMF battery, regularly check the electrolyte level and top up with distilled water as needed.
- Avoid Overloading: Do not connect appliances that exceed the inverter's peak load capacity.
6. Troubleshooting
This section provides basic troubleshooting steps for common issues. For complex problems, please contact Livguard customer support.
| Problem | Possible Cause | Solution |
|---|---|---|
| Inverter not turning ON | No mains power, loose battery connection, low battery, or internal fault. | Check mains supply. Ensure battery terminals are secure and clean. Check battery charge level. If problem persists, contact service. |
| Overload indicator ON | Too many appliances connected, exceeding 780W peak load. | Disconnect some appliances to reduce the load. Press the reset button if available (refer to Figure 3.1 for Thermal Circuit Breaker/Reset SW). |
| Low Battery indicator ON frequently | Battery not charging properly, battery nearing end of life, or frequent/long power cuts. | Ensure mains power is stable for charging. Check battery water level (if applicable). Consider battery replacement if old. |
| No output from inverter | Inverter OFF, output fuse blown, or internal fault. | Ensure inverter is ON. Check for any tripped circuit breakers. Contact service if issue persists. |
