3. Setup and Installation

3.1 Choosing a Location

Select a location that is:

• Dry and protected from moisture.
• Well-ventilated to allow for heat dissipation.
• Cool, away from direct sunlight or heat sources.
• Secure, to prevent accidental movement or damage.

3.2 Battery Connection

Connect the inverter directly to a 12V DC battery bank. Ensure the battery cables are securely fastened to the inverter terminals and battery terminals. Use the provided red cable for the positive (+) connection and the black cable for the negative (-) connection.

• Connect the RED battery cable to the inverter's positive (+) terminal and then to the battery's positive (+) terminal.
• Connect the BLACK battery cable to the inverter's negative (-) terminal and then to the battery's negative (-) terminal.
• Ensure all connections are tight to prevent arcing and overheating.

3.3 AC Output Connection

Plug your 120V AC appliances directly into the two AC outlets on the inverter. Do not exceed the inverter's continuous power rating of 2500W.

Figure 3.2: The inverter provides 2 AC outlets, a USB port, and a Type-C port for connecting various devices.

3.4 Remote Controller Connection

Connect the remote controller cable to the designated port on the inverter. The remote controller allows you to monitor and control the inverter from a convenient location.

3.5 Shore Power Connection (for ATS Function)

For automatic transfer switch functionality, connect an external 120V AC shore power source to the inverter's dedicated shore power input. The inverter will automatically switch to shore power when detected, prioritizing it over battery power.

4. Operating Instructions

4.1 Powering On/Off

To power on the inverter, press and hold the power button on the main unit or the remote controller until the display illuminates. To power off, press and hold the power button again.

4.2 Understanding the LCD Display

The remote controller's LCD display provides critical information about the inverter's operation:

• Battery Voltage (DC Input): Shows the current voltage of your 12V battery bank.
• AC Output Voltage: Displays the 120V AC output voltage.
• Power Output (Watts): Indicates the current power consumption of connected devices.
• Battery Level Indicator: Visual representation of battery charge (100%, 80%, 60%, 40%, 20%).
• Status Indicators: Symbols for High/Low Battery, Overheat, Overload, and other fault conditions.

Figure 4.1: The LCD display provides comprehensive information on battery status, AC output, power consumption, and fault indicators.

4.3 Automatic Transfer Switch (ATS) Function

When both battery power and shore power are connected, the inverter will automatically detect the presence of shore power. If shore power is stable, the inverter will switch to draw power from the shore power source, preserving your battery charge. If shore power is disconnected or unstable, the inverter will seamlessly switch back to battery power. This transition typically occurs within 12 milliseconds, ensuring uninterrupted power supply.

4.4 Connecting Appliances

The inverter can power a wide range of 120V AC appliances and devices, including but not limited to:

• Smartphones, tablets, laptops (via USB, Type-C, or AC outlets)
• LED lights, fans
• Small kitchen appliances (coffee grinders, toasters, microwaves within wattage limits)
• Televisions, entertainment devices
• Electric drills, small power tools
• Refrigerators, freezers (ensure starting wattage is within peak power capacity)

Always ensure the total continuous wattage of connected devices does not exceed 2500W. For devices with motors (e.g., refrigerators, pumps), consider their starting (surge) wattage, which should not exceed the inverter's 5000W peak power.

5. Maintenance

Regular maintenance ensures the longevity and optimal performance of your OLTEANP inverter.

• Cleaning: Keep the inverter clean and free from dust and debris. Use a dry, soft cloth to wipe the exterior. Do not use liquid cleaners or solvents.
• Ventilation: Ensure the ventilation openings are not blocked. Periodically check for any obstructions that might hinder airflow.
• Connections: Regularly inspect all electrical connections (battery cables, AC output, remote control cable) to ensure they are secure and free from corrosion. Tighten any loose connections.
• Storage: If storing the inverter for an extended period, disconnect it from the battery and store it in a cool, dry place. Ensure batteries are properly maintained and charged according to their manufacturer's guidelines.
