5. Installation and Setup
Follow these steps for proper installation of your inverter:
5.1 Site Selection
- Choose a cool, dry, and well-ventilated location.
- Ensure sufficient clearance around the inverter for air circulation.
- Avoid areas with direct sunlight, high humidity, or corrosive gases.
- Place the inverter on a flat, stable surface.
5.2 Battery Connection
- Ensure the inverter is switched OFF and disconnected from the AC mains.
- Connect the red cable from the inverter's +VE terminal to the positive terminal of the 12V battery.
- Connect the black cable from the inverter's -VE terminal to the negative terminal of the 12V battery.
- Double-check all connections for tightness and correct polarity.
- The inverter is compatible with 1 x (12V) battery with capacity between 80 Ah and 220 Ah (Flat Plate, Tubular, SMF types).

Figure 5.2: Home Inverter Battery Buying Guide
This guide provides recommendations for battery capacity based on your home size and typical appliance usage, helping you select the appropriate battery for your inverter system.
5.3 AC Mains Connection
- Plug the inverter's AC input cord into a grounded wall socket.
- Ensure the wall socket provides a stable 110V AC input.
5.4 Appliance Connection
- Connect your appliances (e.g., CFLs, tube lights, ceiling fans, bulbs, LED TVs, refrigerators) to the output socket on the rear panel of the inverter.
- Ensure the total load does not exceed the inverter's peak load capacity of 352 Watts. Recommended running load should be at 75% of peak load.

Figure 5.4: Recommended Appliances and Wattage
This image illustrates the typical wattage consumption of common household appliances, helping you manage the load on your inverter. For example, an LED bulb consumes 9W, a 40" LED TV 75W, a 1200mm fan 80W, and an LED tubelight 18W.
6. Operation
6.1 Powering On/Off
- To power on the inverter, press the On/Off switch on the front panel. The relevant LEDs will illuminate.
- To power off the inverter, press the On/Off switch again.
6.2 Operating Modes (ECO & UPS)
The inverter offers two operating modes, selectable via a switch on the rear panel:
- UPS Mode: In this mode, the output voltage is maintained within a narrow range (180V to 260V) to ensure the safety of sensitive appliances like computers. This mode provides stable power, but may switch to battery backup more frequently during minor voltage fluctuations.
- Eco Mode: In Eco Mode, the voltage range is extended, allowing the inverter to tolerate wider input voltage fluctuations before switching to battery power. This reduces battery usage and extends battery life, making it suitable for less sensitive appliances.
6.3 LED Indicators
Monitor the front panel LEDs for the inverter's status:
- Mains: Green light indicates AC mains power is available and the inverter is charging the battery.
- Charging: Yellow light indicates the battery is currently being charged.
- Eco Mode: Blue light indicates the inverter is operating in Eco Mode.
- UPS Mode: Green light indicates the inverter is operating in UPS Mode.
- Low Battery: Red light indicates the battery charge is critically low. The inverter will soon shut down to protect the battery.
- Overload: Red light indicates that the connected load exceeds the inverter's capacity. Disconnect some appliances immediately.
7. Maintenance
Regular maintenance ensures optimal performance and longevity of your inverter and battery.
7.1 General Cleaning
- Keep the inverter clean and free from dust. Use a soft, dry cloth to wipe the exterior.
- Ensure ventilation openings are not blocked.
7.2 Battery Maintenance
- For tubular or flat plate batteries, regularly check the electrolyte level and top up with distilled water if necessary.
- Keep battery terminals clean and free from corrosion. Apply petroleum jelly to prevent corrosion.
- Ensure the battery is fully charged periodically, especially if not used for extended periods. The inverter's three-stage smart charging helps maintain battery health.
7.3 Fuse Replacement
- If the inverter stops providing output power and the fuse appears blown, disconnect the inverter from both AC mains and the battery.
- Carefully replace the fuse on the rear panel with a fuse of the same rating. Refer to the specifications for the correct fuse rating.
- If fuses blow frequently, contact customer support as there may be an underlying issue.
