- Low Voltage Alarm: The buzzer sounds twice at 1 Hz intervals.
- Low Voltage Protection: The buzzer sounds continuously three times at 1 Hz intervals, and output is shut off.
- Low Voltage Recovery: Output automatically restores when voltage returns to safe levels, and the buzzer stops.
- Overvoltage Protection: The buzzer sounds four times at 1 Hz intervals, and output is shut off.
- Overvoltage Recovery: Output automatically restores when voltage returns to safe levels, and the buzzer stops.
- Overheat Protection: At 80°C ±5°C, the buzzer sounds five times at 1 Hz intervals, and output is shut off.
- Overload Protection: Automatic shutdown for 10 seconds, followed by automatic recovery for 5 seconds. If overload persists, it locks after three consecutive attempts.
- Short Circuit Protection: Immediate shutdown for 1 second, then locks.

6. Installation and Setup
Follow these steps for proper installation:
- Choose a Location: Select a dry, well-ventilated area away from direct sunlight, heat sources, and flammable materials. Ensure sufficient space around the inverter for airflow.
- Mounting: Securely mount the inverter on a stable surface using appropriate fasteners.
- DC Input Connection:
- Ensure the inverter's power switch is OFF.
- Connect the supplied DC cables to the inverter's DC input terminals. Ensure correct polarity: red cable to positive (+), black cable to negative (-).
- Connect the other ends of the DC cables to your 48V battery bank. Again, ensure correct polarity. Tighten all connections securely to prevent loose contacts and arcing.
- Grounding: Connect the inverter's ground terminal to a reliable earth ground using a suitable ground wire. This is crucial for safety.
- Initial Power-Up: After all connections are secure, switch on the 48V DC power source (e.g., battery switch). Then, press the power button on the inverter or use the remote control to turn it ON. The display should illuminate, indicating operational status.
