4. Setup and Installation

Proper installation is crucial for the safe and efficient operation of your inverter charger. Follow these steps carefully:

4.1 Physical Connections

1. DC Terminals: Connect your battery bank to the negative (black) and positive (red) DC terminals located on the back of the inverter. Ensure correct polarity to avoid damage.
2. AC Input/Output Terminals: The AC connect terminal block is on the side of the inverter. Wire your 240V AC input and 120V/240V AC output to these terminals.
3. Grounding Terminal: Connect the grounding terminal, located under the battery temp sensor port, to a proper earth ground. This prevents high voltage on the inverter case in case of leakage.

4.2 Remote Control and Sensors

• Remote Port: Connect the provided LCD remote panel to the 'REMOTE PORT' on the back of the inverter. This panel allows you to control the inverter's operation remotely.
• Battery Temperature Sensor: Connect the optional battery temperature sensor to the 'BATTERY TEMP SENSOR' port. This sensor helps the inverter automatically adjust charging voltage based on battery temperature, prolonging battery life.

4.3 DIP Switch Settings

Five DIP switches (SW1-SW5) are located near the remote port on the back of the inverter. These switches control various operational parameters:

• SW1 (Low Battery Trip Point): Adjusts the voltage level at which the inverter will shut down due to low battery.
• SW2 (AC Input Range): Sets the acceptable voltage range for AC input.
• SW3 (Power Saver Mode): Activates or deactivates the power-saving function.
• SW4 (Frequency): Selects between 50Hz and 60Hz operation.
• SW5 (Mode Selection - Battery/AC Priority): Allows you to prioritize battery power (from renewable sources like wind/solar) before switching to utility power.

4.4 Battery Type Selector

A battery type selector switch is located on the top panel of the inverter. Use this switch to set the correct charging voltage according to your battery type (e.g., LiFePO4, Lithium-Ion, AGM, Gel). Refer to the product label or detailed manual for specific settings for each battery chemistry.

5. Operating Instructions

5.1 Power On/Off

The inverter features a three-position ON/OFF switch on its top panel. Use this switch to power the unit on or off. For remote operation, use the switch on the LCD remote panel.

5.2 Battery Current Control

A battery current control knob is available on the top panel. This knob allows you to adjust the amount of charging current delivered to your batteries, providing flexibility based on battery capacity and charging requirements.

5.3 LED Indicators

The LED indicators on the top panel provide real-time status of the inverter's operation, including:

• Inverter power status.
• Battery charger status (shore power on).
• Charge mode (fast charge, float charge).
• Overload and over temperature warnings.
• Alarm status (check alarms on box).

5.4 Automatic Generator Start (AGS)

The AGS feature allows the inverter to automatically start a compatible generator when the battery voltage drops to a pre-set low alarm level. The generator will then charge the batteries and turn off once charging is complete. Ensure your generator has an auto-start function for this feature to work.

6. Maintenance

• Ventilation: Regularly inspect the inverter's vents and fans to ensure they are free from dust and obstructions. Proper airflow is essential for cooling and preventing overheating.
• Connections: Periodically check all electrical connections (DC, AC, grounding) for tightness and corrosion. Loose connections can lead to poor performance or safety hazards.
• Battery Monitoring: Utilize the battery temperature sensor to ensure optimal charging and discharge conditions, which helps in prolonging battery life.
• Cleaning: Keep the exterior of the inverter clean and free from debris. Use a dry cloth for cleaning. Do not use liquid cleaners.

7. Troubleshooting

If you encounter issues with your SUNGOLDPOWER Inverter Charger, consider the following general troubleshooting steps:

• No Power Output: Check all DC and AC connections. Verify that the ON/OFF switch is in the 'ON' position. Check battery voltage to ensure it is within the operational range.
• Overload Alarm: Reduce the connected load. The inverter has a 12000W peak surge capacity for 20 seconds, but continuous loads should not exceed 4000W.
• Over Temperature Alarm: Ensure the inverter's vents are clear and the fan is operating. Allow the unit to cool down.
• Low Battery Alarm: Check battery charge level. If using AGS, ensure the generator is functioning and connected correctly.
• Incorrect Output Voltage/Frequency: Verify DIP switch settings (SW2 and SW4) are configured correctly for your region and application.
• Remote Control Not Working: Check the cable connection to the remote port.

For persistent issues or complex problems, refer to the detailed troubleshooting section in the full user manual or contact SUNGOLDPOWER technical support.
