4. Package Contents

Verify that all items are included in your package:

• Anern 3600W Hybrid Solar Inverter (Model Anern-3600)
• User Manual (this document)
• Mounting accessories (if applicable, check packaging)
• Communication cable (if applicable, for Wi-Fi module)

5. Setup Instructions

5.1. Unpacking and Inspection

Carefully unpack the inverter and inspect it for any shipping damage. If any damage is found, contact your supplier immediately.

5.2. Mounting the Inverter

Select a suitable location for mounting the inverter. It should be:

• Indoors, protected from direct sunlight, rain, and dust.
• Well-ventilated to ensure adequate heat dissipation.
• Mounted vertically on a solid surface.
• Accessible for wiring and maintenance.

Use appropriate mounting hardware (not always included) to secure the inverter to the wall.

5.3. Wiring Connections

All wiring must be performed with all power sources disconnected. Refer to the wiring diagram (usually found on the inverter or in a detailed wiring section of the full manual) for specific terminal connections.

1. Battery Connection: Connect the 24V battery bank to the inverter's battery terminals. Ensure correct polarity (+ to + and - to -). Use appropriately sized cables and fuses.
2. PV Array Connection: Connect the solar panel array to the PV input terminals. Observe correct polarity and ensure the PV input voltage and current are within the inverter's specifications (Max PV Power 4200W, Max DC Voltage 500VDC).
3. AC Input Connection (Grid/Generator): If connecting to a utility grid or generator, connect the AC input to the designated terminals.
4. AC Output Connection (Loads): Connect your AC loads (appliances) to the inverter's AC output terminals. The inverter features dual AC outputs.
5. Grounding: Connect the inverter's ground terminal to a reliable earth ground.

5.4. Initial Power-Up and Configuration

After all connections are secure and verified:

1. Turn on the battery breaker/switch.
2. Turn on the PV array breaker/switch.
3. If applicable, turn on the AC input breaker.
4. The inverter will power on and the LCD display will illuminate.
5. Use the control buttons on the LCD panel to configure system settings such as charging current, voltage thresholds, and priority modes according to your requirements.

6. Operating Modes

The inverter supports various charging and output modes to optimize power usage.

6.1. Charging Modes

You can select one of four charging modes:

• Only Solar: The inverter charges the battery exclusively from solar energy.
• Mains Supply Priority: The inverter prioritizes charging from the utility grid (mains supply). Solar energy will supplement if available.
• Solar Priority: The inverter prioritizes charging from solar energy. The utility grid will be used if solar power is insufficient.
• Mains Supply and Solar Charging Combination: The inverter uses both mains supply and solar energy to charge the battery simultaneously.

6.2. Output Modes

The inverter offers two output modes for continuous power supply:

• Power Bypass: In this mode, loads are powered directly from the AC input (utility grid or generator), bypassing the inverter. The inverter acts as a charger.
• Inverter Output: Loads are powered by the inverter, drawing energy from the battery or directly from the PV array (if in battery-free mode).

7. Maintenance

Regular maintenance ensures optimal performance and longevity of your inverter:

• Cleaning: Periodically clean the inverter's exterior and ventilation openings to prevent dust buildup, which can hinder cooling. Use a dry, soft cloth.
• Connection Check: Annually inspect all electrical connections for tightness and corrosion. Loose connections can cause overheating and poor performance.
• Environmental Check: Ensure the installation environment remains within specified temperature and humidity ranges.
• Battery Inspection: If using lead-acid batteries, check electrolyte levels and terminal condition as per battery manufacturer guidelines.
• Firmware Updates: Check the manufacturer's website for any available firmware updates for improved performance or new features.
