4. Setup Instructions
4.1 System Diagram
The following diagram illustrates a typical system setup for the Anern 4200W Hybrid Solar Inverter, showing connections for solar panels, batteries, grid, generator, and household appliances.
Image: Typical system connection diagram.
4.2 Mounting the Inverter
- Choose a vertical, non-flammable surface for mounting.
- Ensure adequate clearance around the inverter for proper ventilation (at least 20 cm on all sides).
- Mount the inverter securely using appropriate fasteners.
4.3 Wiring Connections
All wiring must comply with local electrical codes and regulations. Use recommended cable sizes.
- Battery Connection: Connect the battery bank to the inverter's battery input terminals. Ensure correct polarity. The inverter supports lead-acid, gel, and lithium batteries. For lithium batteries, activate the 'Custom' option in Program 05 if not using a PACE BMS.
- PV Array Connection: Connect the solar panel array to the PV input terminals. Observe maximum PV input voltage (500V DC) and current.
- AC Input Connection: Connect the AC grid power to the AC input terminal.
- AC Output Connection: Connect your loads to the main and secondary AC output terminals. The inverter features dual AC outputs. The primary and secondary outputs are typically used together. If PV or grid power is unavailable and battery voltage is low, the primary circuit shuts down, and only the secondary output remains active to conserve energy.
- Grounding: Connect the inverter's ground terminal to a reliable earth ground.

5. Operating Instructions
5.1 LCD Display and Settings
The LCD display provides real-time information about the system status, battery voltage, PV input, AC output, and various operational parameters. Use the touch function buttons to navigate through the menus and adjust settings. The high-resolution RGB LCD display is easy to read even in daylight.
5.2 Charging Modes
The inverter offers four selectable charging modes to optimize battery charging based on your energy sources:
- Solar Priority: Solar power is the primary source for charging.
- Solar Only: Only solar power is used for charging.
- Utility Priority: Grid power is the primary source for charging.
- Solar Hybrid and Utility: Combines solar and utility power for charging.

5.3 Output Modes
Three output modes are available to meet different application requirements:
- Solar Priority (SUB): Solar power is the primary source for loads, then battery, then utility.
- Utility Priority (USB): Utility power is the primary source for loads, then solar, then battery.
- SBU: Solar power is the primary source for loads, then battery, then utility.
5.4 Dual AC Outputs
The inverter is equipped with two AC output terminals: a primary and a secondary. Under normal operating conditions, both outputs are active. In scenarios where there is no PV or grid power, and the battery voltage drops too low, the primary output will shut down, leaving only the secondary output active to conserve battery energy.
6. Maintenance
Regular maintenance ensures optimal performance and longevity of your inverter:
- Cleaning: Periodically clean the exterior of the inverter with a dry cloth. Ensure ventilation openings are free from dust and debris.
- Connections: Check all electrical connections regularly for tightness and signs of corrosion.
- Environment: Ensure the installation environment remains within specified temperature and humidity ranges.
- Battery Inspection: If using lead-acid batteries, check electrolyte levels and terminal conditions as per battery manufacturer guidelines.
7. Troubleshooting
If you encounter issues with your inverter, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Inverter not turning on | No battery connection, low battery voltage, power switch off. | Check battery connections, ensure battery voltage is sufficient, turn on the power switch. |
| No AC output | Overload, short circuit, high temperature, battery low. | Reduce load, check for short circuits, allow inverter to cool, charge battery. |
| PV charging not working | No PV input, PV voltage too low/high, PV polarity reversed. | Check PV connections, ensure PV voltage is within range, verify PV polarity. |
| Error code displayed | Specific system fault. | Refer to the inverter's LCD display for the specific error code and consult the full manual for detailed solutions. |
For persistent issues or error codes not listed, please contact customer support.
