6.1 System Diagram
6.2 Connection Steps
- Mounting: Choose a suitable location for mounting the inverter, ensuring it is well-ventilated and protected from direct sunlight and moisture.
- Battery Connection: Connect the battery bank to the inverter's battery input terminals (10). Ensure correct polarity (+ to + and - to -). The inverter supports 12VDC (for 2KW model) or 24VDC (for 3.2KW model) battery systems.
- PV Input Connection: Connect your solar panels to the PV input terminals (9). Ensure the PV input voltage is within the specified MPPT range (30-400VDC) and the open circuit voltage does not exceed 400VDC.
- AC Input Connection (Optional): If connecting to a utility grid or generator, connect the AC input source to the AC input terminals (7).
- AC Output Connection: Connect your household appliances or load to the AC output terminals (8).
- Communication Port: If using smart monitoring, connect the WIFI module to the COMM / WiFi port.
- Grounding: Ensure the inverter is properly grounded.
- Circuit Breakers: Install appropriate circuit breakers on all input and output lines as a safety measure.
Important: Always follow the starting and shutdown sequences outlined in the Safety Instructions (Section 2).
7. Operating Modes
The Anern Hybrid Solar Inverter offers flexible operating modes to suit various power requirements and energy sources.
7.1 Loading Modes
The inverter can operate in three primary loading modes:
- Priority Solar Energy: The inverter primarily uses solar energy to power the load and charge the battery.
- Solar + Utility at the Same Time: Solar energy is prioritized, but if insufficient, the utility grid supplements the power to the load and battery.
- Solar Charge Battery ONLY: Solar energy is exclusively used to charge the battery, with no direct power to the load.
7.2 Output Modes
The inverter provides two main output modes:
- Solar Priority Output, then Utility: The inverter prioritizes solar power for the load. If solar power is insufficient, it switches to utility power.
- Solar Priority Output, then Battery, finally Electricity Suppliers: Solar power is prioritized. If solar power is insufficient, it draws from the battery. If both solar and battery power are insufficient, it switches to the utility grid.
The default operating mode is PV priority. When the PV input is insufficient, the system will automatically utilize the battery and/or utility power as configured.
8. Maintenance
Regular maintenance ensures the longevity and optimal performance of your Anern Hybrid Solar Inverter.
- Cleaning: Keep the inverter's exterior clean and free from dust. The built-in anti-dusk kit helps, but periodic cleaning is still recommended.
- Ventilation: Ensure that the ventilation openings are not blocked. Clear any obstructions to maintain proper airflow.
- Connections: Periodically check all electrical connections (PV, battery, AC input/output) to ensure they are tight and free from corrosion.
- Battery Health: Monitor battery performance and ensure proper charging cycles. The smart battery charge design helps optimize battery life.
- Environmental Check: Ensure the operating environment remains within the specified temperature and humidity ranges.
- Firmware Updates: If your model includes WIFI and smart monitoring, check for available firmware updates through the mobile application to ensure the inverter runs with the latest features and improvements.
9. Troubleshooting (FAQ)
This section addresses common questions and issues you might encounter.
Q: Can inverters be connected in series or parallel?
A: No, these inverters are designed for standalone operation and cannot be connected in series or parallel.
Q: What types of batteries can be used?
A: Lead-acid batteries, gel batteries, Lithium Iron Phosphate (LiFePo4), and other lithium batteries can be used. For the 3.2KW model, a 24V battery is required, and for the 2KW model, a 12V battery is required. The battery capacity should not be less than 100AH.
Q: Can it be used with air conditioners, water pumps, and wind turbines?
A: It can be used with air conditioners. However, it is not recommended for use with water pumps and wind turbines due to their specific load characteristics.
Q: How to choose the power of the inverter according to household appliances?
A: If your household appliances include inductive loads (e.g., refrigerators, washing machines, air conditioners), their starting power can be significantly higher than their running power. The inverter's power rating should be at least three times the total starting power of these inductive load appliances. Failure to do so may prevent the appliances from starting or damage the inverter.
Q: Is it possible to use PV, battery, and grid supply at the same time?
A: Yes. The inverter operates in a default PV priority mode. When the PV input is insufficient to meet the load demand or charge the battery, the system will automatically draw power from the battery and/or the utility grid as configured.
Q: What if the inverter displays a 'FAULT' indicator?
A: A 'FAULT' indicator suggests an error condition. Refer to the detailed troubleshooting section in the full product manual for specific fault codes and corrective actions. Common causes include overload, short circuit, or internal system errors.
10. User Tips
- Battery Capacity: Ensure your battery bank has a capacity of at least 100AH for optimal performance and stability.
- Smart Monitoring: Utilize the available WIFI feature (if applicable to your model) and the mobile app for iOS or Android to monitor the inverter's running status and energy production remotely.
- Battery Life Optimization: The inverter's smart battery charge design helps extend battery life. Ensure proper battery type selection and settings for maximum benefit.
- Inductive Load Sizing: When calculating inverter size, always account for the surge power of inductive loads. A general rule is to multiply the continuous power of inductive loads by three for their starting power requirement.
