ABOUT THIS MANUAL

Purpose
This manual describes the operation and troubleshooting of this unit. Please read this manual carefully before operations. Keep this manual for future reference.
Scope
This manual provides safety guidelines as well as information on tools and wiring.

SAFETY INSTRUCTIONS

WARNING: This chapter contains important safety and operating instructions. Read and keep this manual for future reference.

1. Before operating your Pure Sine Wave Inverter, please review the safety precautions outlined in this manual to ensure safe and trouble-free operation. It is essential to follow these guidelines to prevent accidents and protect yourself and others from harm.
2. Do not disassemble the unit. Take it to a qualified service center when service or repair is required. Incorrect re-assembly may result in a risk of electric shock or fire.
3. The inverter should be installed in a dry, well ventilated environment.
4. Do not expose the inverter to the heat, moisture, flammable, explosive, corrosive environment, dry cloth cleaning, and avoid water.
5. CAUTION – Only qualified personnel can install this device with battery.
6. Fuse/MCB is provided as over-current protection for the AC Mains supply.
7. GROUNDING INSTRUCTIONS -This inverter/charger should be connected to a permanent grounded wiring system. Be sure to comply with local requirements and regulations to install this inverter.
8. NEVER cause AC output and DC input short circuited. Do NOT connect to the mains when DC input short circuits.
9. Warning!! Only qualified service persons are able to service this device. If errors still persist after following the troubleshooting table, please send this inverter back to the local dealer or service center for maintenance.

WARNING: FIRE HAZARD
Even if the inverter is switched off, there might be a spark when connected to a battery (powerful 1000W-2000W inverters create a strong spark). This is normal and caused by capacitors in the inverter circuit which require initial charging at connection. Once
charged, reconnection of the inverter within a short time frame should not cause a spark again.

INTRODUCTION

Welcome to the user manual for your “LiGEN Power” Pure Sine Wave Inverter! This manual is designed to provide you with all the necessary information to effectively and safely operate your inverter. Whether you’re using it for backup power during outages, in off-grid locations, or for any other application, this inverter offers reliable and high-quality power conversion with portable size.

Starting Operation

• Connect the male and female XT 60/90 connectors on the back panel of the inverter. Plug the AC male top into the AC mains supply. Connect a load to the female socket located on the back panel of the Inverter.
• After connecting the XT 60/90 connector, a beep sound comes from the buzzer, and the status of the inverter starts to appear on the LCD.
• Press the power button or switch on the front control panel of the inverter unit to turn it ON. Once powered ON, the inverter will perform a self-check routine to ensure proper operation.
• Observe the LCD display on the control panel of the inverter unit. The LCD display provides valuable information about the operating status of the inverter, including power status, battery voltage, AC input and output status, charging current, load wattage, temperature (in Celsius), overload conditions, over-temperature conditions, and fault notifications.
• After powering ON, this system can run a load solely on battery power in the event of a power outage. When AC mains power is available, the inverter automatically switches to Normal mode without interrupting the load, simultaneously charging the  battery. This transition is indicated by a clicking sound as the internal transfer relay changes position, and the LCD display shows the current status of the inverter
• When AC mains power is available, input power is directly transferred to the output. It doesn’t matter if the power button is on or off. The power button is only for turning the inverter on or off during a power outage
• The system will begin to draw power from the batteries and use it to supply power to the load. The load will continue to operate uninterrupted in case of a power failure, provided the inverter power button is turned on. Otherwise, the load will be interrupted.
• Manual Bypass (Only for above 600VA model)
• Use the bypass mode as a temporary solution while addressing the inverter malfunction. Once the inverter is repaired or replaced, switch back to normal operation mode to utilize its full functionality.
• The above steps will complete the functional test of the Inverter. If all areas pass the system is ready for use. If something fails, figure out the reason before proceeding or contact the service center.

Note: When powerful appliances are connected to the inverter, the battery voltage drops more quickly, triggering a low battery shutdown sooner. This means that even after shutdown, there may still be power remaining in the battery. Conversely, lighter loads allow for deeper battery discharge before shutdown. It’s important to consider connected appliance power requirements to optimize battery usage.
