3. Setup and Installation

Proper installation is crucial for the safe and efficient operation of your hybrid solar inverter. Please follow all local electrical codes and safety guidelines. It is recommended that installation be performed by a qualified professional.

3.1 Wiring Diagram

The inverter supports dual photovoltaic (PV) inputs and dual AC outputs. Ensure all connections are secure and correctly polarized.

Figure 3: Comprehensive wiring diagram showing connections for PV, battery, AC input, and AC output.

3.2 Connection Guidelines

• PV Input: Max PV open circuit voltage 500VDC. MPPT voltage range 90-450VDC. Suggested cable: 10 AWG/6mm². Connect solar modules in series for optimal performance.
• Battery Connection: Compatible with 48V lead-acid/lithium batteries. Recommended cable and terminal size: Wire size 2 AWG/Cable 25mm². Recommended Fuse: 150A.
• AC Input (Utility/Generator): 230 VDC. Maximum AC input voltage: 300VAC. Max AC charging current: 160A. Suggested cable: 10AWG/6mm². Recommended switch: 63A.
• AC Output: Output power 10200W. Output voltage: 220V/230V. Suggested cable: 10AWG/6mm². Recommended breaker: 63A.

Note: The inverter's output is 230V. For 110V/120V US home appliances, a separate converter (not included) is required to step down the voltage.

4. Operating Modes

The inverter offers flexible charging and output modes to suit various energy management needs.

4.1 Charging Modes

• CSO (Solar First): Solar energy charges the battery as a priority. The utility company only charges the battery when solar input is unavailable.
• SNU (Solar and Utility): Solar energy and utility power charge the battery simultaneously. (Default mode)
• OSO (Only Solar): Solar energy is the sole source of charging, regardless of utility availability.

4.2 Output Modes

• Solar First: Prioritizes solar power for loads. If solar is insufficient, the grid or battery supplements.
• Mains First: Prioritizes utility power for loads. Solar power is used when utility is unavailable or for charging.
• SBU Priority: Solar energy powers loads first. If solar is insufficient, battery power is used. If both are insufficient or battery voltage drops, utility power takes over.

4.3 RGB Light Indicators

The inverter features RGB lighting to indicate its current operating mode:

• Purple: PV Mode (Solar power is active).
• Red: Battery Mode (Operating from battery power).
• Blue: Utility Mode (Operating from grid/utility power).
• White: Stationary Mode (Idle or standby).

Figure 5: RGB lighting indicates the inverter's current operational status.

5. Battery Compatibility

The inverter is designed to work with various 48V battery types, including Lead-Acid (Sealed, AGM, Gel, Flooded) and Lithium batteries.

• The inverter can be used without batteries.
• For Lithium batteries, it can only be connected to PACE BMS. It is not compatible with BMS from other manufacturers.
• The inverter cannot communicate with other battery brands.
• If using a Lithium battery, select "User defined" in program 05 to configure battery parameters.

9. Troubleshooting

If you encounter any issues with your Anern 10.2KW Hybrid Solar Inverter, please refer to the following general guidelines. For specific error codes or persistent problems, consult the detailed troubleshooting section in the full product manual or contact customer support.

• No Power/Display Off: Check all power connections, including battery and AC input. Ensure the on/off switch is in the 'on' position. Verify battery voltage is within the operating range.
• No AC Output: Check for overload conditions. Reduce the load if necessary. Verify AC output breaker is not tripped. Check for fault indicators on the LCD screen.
• No Solar Charging: Ensure PV panels are connected correctly and receiving sufficient sunlight. Check PV input voltage and current on the display. Verify MPPT controller is functioning.
• Battery Not Charging: Check battery connections and ensure battery type settings are correct in the inverter's menu (Program 05). Verify AC input is present if using utility charging.
• Error Codes: If an error code appears on the LCD, note the code and refer to the comprehensive manual for its meaning and recommended actions.
