5. Installation (Setup)
5.1 Choosing a Location
Select a suitable location for the inverter:
- Mount vertically on a non-flammable surface.
- Ensure sufficient clearance (at least 20 cm) around the unit for proper airflow.
- Avoid direct sunlight, high temperatures, humidity, and corrosive gases.
5.2 Battery Voltage Selection (12V System)
This inverter is designed for a 12V battery system. Ensure your battery bank is configured for 12V. Connecting a 24V battery bank to a 12V inverter will cause immediate damage.
Figure 5.1: This inverter requires a 12V battery system. Do not connect to 24V.
5.3 Wiring Connections
Follow these steps for wiring connections. Always ensure the inverter is OFF before making any connections.
- Grounding: Connect the ground terminal of the inverter to a reliable earth ground.
- Battery Connection: Connect the positive (+) and negative (-) terminals of your 12V battery bank to the corresponding Battery Input terminals on the inverter. Ensure tight connections. The inverter is compatible with FLD, AGM, Gel, and LiFePo4 12V batteries.
- Solar Panel Connection: Connect your solar panel array to the PV Input terminals. Ensure the total PV power does not exceed 2000W and the MPPT voltage range (90-430Vdc) is respected.
- AC Input Connection: Connect the utility grid or a generator to the AC In Port.
- AC Output Connection: Connect your AC loads (appliances) to the AC Out Port.

6. Operation
6.1 LCD Display and Controls
The LCD display provides real-time information about the system status, input/output voltages, battery charge, and load levels. Use the touchable buttons (ESC, UP, DOWN, ENTER) to navigate through menus and adjust settings.
Figure 6.1: The LCD screen provides comprehensive system information and allows for configuration adjustments.
6.2 Charging Modes
The inverter offers four optional charging modes to optimize battery charging:
- Solar Priority: Solar power is prioritized for charging.
- AC Priority: AC utility/generator power is prioritized for charging.
- Solar and AC: Both solar and AC power are used for charging.
- Solar Only: Only solar power is used for charging.
The MPPT (Maximum Power Point Tracking) solar charger maximizes efficiency by continuously monitoring and adjusting the solar panel's operating voltage to extract the maximum available power. The AC charger supports a 6-phase charging process for extended battery life.
Figure 6.2: MPPT technology ensures maximum power harvest from solar panels within the 90-430Vdc range.

6.3 Output Modes
The inverter provides three output modes:
- Utility Priority: AC loads are primarily powered by the utility grid.
- Solar Priority: AC loads are primarily powered by solar energy and batteries.
- Battery Priority: AC loads are primarily powered by batteries.
ECO Mode: This mode reduces power consumption to less than 15W when the load is low, preventing unnecessary battery discharge. The inverter will automatically restart when AC power is restored.

8. Troubleshooting
This section addresses common issues you might encounter:
| Problem | Possible Cause | Solution |
|---|---|---|
| Inverter alarm sounds constantly. | The inverter is in protection mode (e.g., overload, low voltage). | Check the LCD for specific error codes. Identify and resolve the underlying issue (e.g., reduce load, check battery voltage). |
| Low voltage alarm sounds even with a fully charged battery. | Insufficient battery capacity (Ah) for the load, or long/thin battery cables causing voltage drop. | Increase battery bank capacity or use thicker, shorter battery cables to minimize voltage drop. |
| Inverter does not recognize solar panels. | Incorrect PV wiring, PV voltage outside MPPT range, or faulty panels/connections. | Verify PV wiring polarity and connections. Check PV voltage to ensure it's within the 90-430Vdc MPPT range. Inspect panels for damage. |
| No AC output. | Inverter is off, battery is low, overload, or fault condition. | Ensure inverter is ON. Check battery voltage. Reduce load. Check for error codes on LCD. |
