Setup and Installation

Follow these steps for safe and correct installation of your inverter.

1. Mounting the Inverter:

Choose a location that is dry, cool, and well-ventilated.
Ensure there is sufficient space around the inverter for airflow, especially around the cooling fan.
Mount the inverter securely on a stable surface using appropriate fasteners.

2. DC Input Connection:

Ensure the inverter's power switch is in the OFF position.
Connect the RED battery cable to the Positive (+) terminal of the 48V DC battery.
Connect the other end of the RED battery cable to the Positive (+) terminal on the inverter.
Connect the BLACK battery cable to the Negative (-) terminal of the 48V DC battery.
Connect the other end of the BLACK battery cable to the Negative (-) terminal on the inverter.
Tighten all connections securely using the provided spanner. Loose connections can cause voltage drops and overheating.

3. Grounding Connection:

Connect one end of the provided earth wire to the grounding terminal on the inverter.
Connect the other end of the earth wire to a proper earth ground point (e.g., vehicle chassis, ground rod, or house ground system).

4. Remote Control Connection:

Wired Remote Control: Plug the wired remote control cable into the designated port on the inverter's front panel.
Wireless Remote Control: The wireless remote operates independently. Ensure it has a working battery.

Operation

1. Powering On the Inverter:

After ensuring all connections are secure and correct, switch the inverter's main power switch to the ON position.
The LCD display will illuminate, showing current input voltage, output voltage, and other operational parameters. The power indicator should be GREEN.
If using the wired remote, ensure the main switch is ON, then use the remote's power button to activate the inverter.
If using the wireless remote, ensure the main switch is ON, then use the remote's ON button. Note that the wireless remote may draw standby power even when the inverter is off but the main switch is ON.

2. Connecting AC Devices:

Plug your AC appliances into the dual AC outlets on the front panel.
Ensure the total wattage of all connected AC devices does not exceed 4000W.

3. Using USB Charging Ports:

Connect your USB-C compatible devices to the 60W PD USB-C port for fast charging.
Connect your USB-A compatible devices to the 3 USB-QC3.0 ports for fast charging.

4. Understanding the LCD Display:

The intelligent LCD display provides real-time monitoring of the inverter's status:

Troubleshooting

This section addresses common issues you might encounter. For problems not listed here, contact customer support.

Problem	Possible Cause	Solution
Inverter does not turn on.	Loose battery connections. Battery voltage too low. Main power switch off. Blown fuse.	Check and tighten all battery cable connections. Charge the battery. Ensure the main power switch is ON. Check and replace fuses if necessary (use only specified fuse types).
No AC output.	Overload protection activated. Over-temperature protection activated. Low/Over voltage protection activated. Connected appliance faulty.	Reduce the load by disconnecting some appliances. Allow the inverter to cool down. Ensure proper ventilation. Check battery voltage and charge if low, or disconnect if too high. Test the appliance with another power source.
LCD display shows error code (e.g., F10, F12).	F10: Over-voltage protection. F12: Low-voltage protection. Other codes indicate specific faults (refer to display icons in Figure 5).	For F10, check battery voltage; it may be too high. For F12, charge the battery; voltage is too low. Address the specific fault indicated by the code. Often, cycling the power (OFF then ON) can reset the inverter after resolving the underlying issue.
Buzzing noise from inverter.	Normal operation under load. Loose internal components (rare).	Some buzzing is normal, especially with inductive loads. If excessive or unusual, contact customer support.
