2. Safety Information
Please read all instructions and warnings carefully before installation and operation. Keep this manual for future reference.
- Ensure proper ventilation around the inverter to prevent overheating.
- Do not disassemble the inverter. Refer all servicing to qualified personnel.
- Keep the inverter away from moisture, flammable materials, and corrosive substances.
- Always disconnect all power sources (solar, utility, battery) before performing any maintenance or wiring.
- Ensure all wiring is correctly sized and properly terminated according to local electrical codes.
3. Installation and Setup
3.1 Unpacking and Inspection
Upon receiving the inverter, carefully unpack it and inspect for any shipping damage. Ensure all components are present.
3.2 Mounting the Inverter
Mount the inverter in a clean, dry, and well-ventilated area. Ensure there is sufficient clearance around the unit for proper airflow. Avoid direct sunlight and heat sources.
3.3 Wiring Connections
Refer to the system diagram below for correct wiring connections. All connections must be secure to prevent loose contacts, which can cause overheating or malfunction.
Figure 2: System wiring diagram for the solar inverter.
- Battery Connection: Connect the battery bank to the inverter's battery terminals. Ensure correct polarity (positive to positive, negative to negative). The inverter features intelligent battery charging for optimal performance.
- AC Input Connection: Connect the utility grid or a generator to the AC input terminals. The inverter is compatible with mains voltage and generator power.
- Solar Panel (PV Array) Connection: Connect your solar panels to the PV input terminals. The maximum open circuit voltage for the photovoltaic array is 80VDC, and the maximum power is 1200W. Ensure the PV array specifications do not exceed these limits.
- AC Output Connection: Connect your household appliances or load to the AC output terminals.
4. Operating Instructions
4.1 Powering On/Off
- To Power On: Ensure all connections are secure. Turn on the battery breaker first, then the AC input breaker (if applicable), and finally the solar PV breaker (if applicable). Press and hold the power button on the inverter until the display illuminates.
- To Power Off: Disconnect all loads from the inverter. Turn off the solar PV breaker, then the AC input breaker, and finally the battery breaker. Press and hold the power button on the inverter until the display turns off.
4.2 Operating Modes
The inverter supports multiple operating modes, which can be selected via the LCD interface:
- Inverter Mode: Converts DC power from batteries (charged by solar or AC) into AC power for your loads.
- AC Charger Mode: Charges the connected batteries using AC utility power or a generator.
- Solar Charger Mode: Charges the connected batteries using power from the solar panels.
You can select different modes to generate different output based on your power source availability and load requirements. The LCD allows for adjustment of the battery charging current, especially useful for the cold start function.
4.3 LCD Display and Controls
The LCD display provides real-time information about the system status, including input voltage, output voltage, battery charge level, and selected operating mode. Use the control buttons (UP, DOWN, ESC, ENTER) to navigate menus and adjust settings.
5. Maintenance
Regular maintenance ensures the longevity and optimal performance of your solar inverter.
- Cleaning: Keep the inverter's exterior clean and free from dust. Use a dry cloth for cleaning. Do not use liquid cleaners.
- Ventilation: Ensure that the ventilation openings are not blocked. Clear any dust or debris from the vents regularly.
- Connections: Periodically check all electrical connections for tightness. Loose connections can lead to overheating and power loss.
- Battery Inspection: If using lead-acid batteries, check their fluid levels and terminals for corrosion as per battery manufacturer guidelines.
6. Troubleshooting
The inverter is designed with built-in protection features. If the inverter experiences an issue, it may display an error code or shut down automatically.
- Overload Protection: If the connected load exceeds the inverter's capacity (2400W), the inverter will shut down. Disconnect some loads and restart the inverter.
- Over Temperature Protection: If the internal temperature of the inverter becomes too high, it will shut down. Ensure adequate ventilation and clear any obstructions from the cooling vents. Allow the unit to cool down before restarting.
- Short Circuit Protection: In case of a short circuit at the output, the inverter will shut down to prevent damage. Identify and resolve the short circuit before restarting.
- No Power Output: Check all input connections (battery, AC, solar) and ensure they are properly connected and supplying power. Verify the inverter is powered on and not displaying any error codes.
For persistent issues, contact customer support.
