4. Setup and Installation

4.1 Mounting the Inverter

Mount the inverter in a dry, well-ventilated area, away from direct sunlight and heat sources. Ensure there is sufficient clearance around the unit for airflow. The inverter can be wall-mounted using the integrated mounting brackets.

4.2 Wiring Connections

Follow the connection diagram carefully to ensure correct and safe installation. All wiring should be performed by a qualified individual.

4.4 Adjustable Charging Current

The maximum charging current can be adjusted from 0-35A. Setting the value to 0A will disable the charging function. This setting allows for optimization based on battery capacity and type.

5. Operating Modes

The OAE FT-2000W12V inverter offers five distinct operating modes to suit various power management needs:

1. AC/Line Priority Mode: In this mode, the inverter prioritizes AC utility power as the primary input. It provides AC output to loads and automatically charges the connected battery. If AC utility power fails, the inverter seamlessly switches to battery power.
2. Battery Priority Mode: This mode prioritizes battery power supply. The inverter will draw power from the battery to supply loads. Upon reaching a low voltage protection threshold, it will transfer to AC utility power. Once the battery is sufficiently recharged, it will revert to battery power.
3. ECO Mode: Designed for energy saving, the inverter enters a sleep state and stops output when the load is less than 10% of its capacity. When the load exceeds 10%, it automatically reactivates and resumes normal inversion.
4. Generator Mode: This mode is used when an unstable generator (120V) is connected to the inverter's AC input. The inverter's built-in AVR (Automatic Voltage Regulator) stabilizes the input, automatically matching 50Hz/60Hz frequency, and regulates the output voltage within the normal operating range.
5. Unattended Mode: When the battery voltage drops to a low level, the inverter enters a standby (power-saving) state. It will automatically restore normal inverter output once the battery voltage recovers to a user-defined value (e.g., through solar charging), enabling fully automatic operation without manual intervention.

6. Maintenance

Regular maintenance ensures the longevity and optimal performance of your inverter:

• Keep the inverter clean and free from dust. Use a dry cloth for cleaning.
• Ensure ventilation openings are not blocked.
• Periodically check all electrical connections for tightness and corrosion.
• Inspect battery terminals for corrosion and clean if necessary.
• Monitor the inverter's display for any error codes or warnings.

7. Troubleshooting

This section provides guidance for common issues. For problems not listed here, contact customer support.

Important: Do not overload the inverter. Ensure the total wattage of connected appliances does not exceed the inverter's rated capacity.
