5. Setup and Installation

5.1 System Diagram

The following diagram illustrates a typical hybrid solar energy storage system setup:

Figure 4: Hybrid Solar Energy Storage System Diagram

This diagram shows the connection of solar panels, grid, generator, inverter, battery (lithium/lead-acid), and home loads, with cloud and app monitoring capabilities.

5.2 Batteryless Mode

The inverter supports a batteryless mode, allowing it to power loads directly from PV/AC sources without a connected battery. This offers a simpler, plug-and-play wiring solution compared to traditional battery-dependent systems.

5.3 Battery Connection and Type Selection

The inverter is compatible with both lithium and lead-acid batteries. When connecting a lithium battery, ensure compatibility with the inverter's communication protocol via the RJ45 BMS port.

Figure 6: Selectable Battery Types

The inverter supports the following battery types, configurable via the display:

• AGM (default)
• FLD (Flooded)
• LIB (Lithium Ternary Battery)
• FEL (Lithium Iron)
• CUS (User-Defined)

For lithium battery connections, verify the compatibility of the battery's protocol with the inverter. There are two connectors on the lithium battery: an RJ45 port for BMS communication and a power cable.

5.4 Dual AC Output

The inverter provides two AC outputs:

• Main Output: Designed for connecting to a rated power load.
• Second Output: Can be connected to a load of up to one-third of the rated power.

6. Operation

6.1 Solar Charging Priority Modes

The inverter offers flexible solar charging priority settings to optimize energy usage:

Figure 7: Solar Charging Priority Options

• Solar First: Solar energy is prioritized to charge the battery. The utility grid will only charge the battery if solar energy is unavailable.
• Solar and Utility: Both solar energy and the utility grid will charge the battery simultaneously.
• Only Solar Charging: Solar energy is the exclusive charging source, regardless of utility availability.

These modes can be configured via the inverter's LCD display or optional WiFi monitoring application.

7. Maintenance

To ensure optimal performance and longevity of your Anern Hybrid Solar Inverter, regular maintenance is recommended:

• Cleaning: Keep the inverter's exterior clean and free from dust and debris. Ensure ventilation openings are unobstructed.
• Connections: Periodically check all electrical connections (PV, battery, AC input/output) for tightness and signs of corrosion.
• Environment: Ensure the inverter is operating within its specified temperature and humidity ranges. Avoid exposure to direct sunlight or excessive moisture.
• Firmware Updates: If available, consider updating the inverter's firmware via the optional WiFi module to benefit from performance improvements and new features.

8. Troubleshooting

This section provides guidance on common issues you might encounter:

• No Power/Display Off: Check AC input, battery connections, and the ON/OFF switch. Ensure sufficient PV input if operating in solar-only mode.
• Fault Indicator On: Refer to the inverter's display for specific error codes. Common faults include over-voltage, under-voltage, overload, or short circuit. Address the underlying cause before restarting.
• Low Output Power: Verify PV input voltage and current are within specifications. Check battery charge level and health. Ensure loads do not exceed the inverter's rated capacity.
• Battery Not Charging: Check PV panel connections and ensure sufficient sunlight. Verify AC input if utility charging is enabled. Confirm battery type settings are correct.
• BMS Communication Issues: Ensure the RJ45 cable is securely connected and the lithium battery's protocol is compatible with the inverter.

For persistent issues, consult a qualified technician or contact customer support.

9. User Tips

• Battery Compatibility: The inverter is suitable for LiFePo4 batteries, as it supports both Lithium and Lead-acid types. Always ensure the specific battery's BMS protocol is compatible.
• PV Input Current: The inverter is designed to handle a maximum PV input current of 27 Amperes, as indicated in the specifications (Max PV Input Current/Power: 27A/9000W).
• Monitoring: Utilize the optional WiFi module for remote monitoring to keep track of your system's performance and settings from anywhere.
