Temank 4000W 24V to 110V Hybrid Solar Inverter

1. Introduction

This manual provides essential information for the safe and efficient operation of your Temank 4000W 24V to 110V Hybrid Solar Inverter. This device integrates a solar charge controller, inverter, and AC charger into one unit, offering uninterruptible power support. Please read this manual thoroughly before installation and use, and retain it for future reference.

2. Safety Information

Adhering to these safety guidelines is crucial for preventing injury and damage to the inverter. Failure to follow these instructions may result in electric shock, fire, or severe damage to the unit.

• Installation Environment: This unit is NOT waterproof. It must be installed indoors with good ventilation or in a sheltered area protected from rain, moisture, and direct sunlight.
• Ventilation: Ensure adequate airflow around the inverter to prevent overheating. Do not block ventilation openings.
• PV Voltage Guidance: The maximum solar input voltage is 350VDC. For safe and stable operation, the connected solar panels' maximum open-circuit voltage should not exceed 280VDC. The PV start-up voltage must be greater than 90VDC to ensure proper initial battery charging.
• Parallel Operation: This inverter does NOT support parallel operation with other inverters.
• Qualified Personnel: Installation and maintenance should only be performed by qualified personnel.
• Electrical Safety: Always disconnect all power sources (solar, battery, utility) before performing any wiring or maintenance. Use appropriate personal protective equipment.

3. Product Features

4. Setup and Installation

Proper installation is critical for the inverter's performance and safety. Ensure all connections are secure and correctly polarized.

4.1 Site Selection

• Install indoors or in a sheltered, well-ventilated area.
• Avoid areas with excessive dust, moisture, or corrosive gases.
• Ensure sufficient clearance around the unit for cooling.

4.2 Wiring Connections

Follow the wiring diagram carefully. All wiring should comply with local electrical codes.

• PV Input: Connect solar panels to the PV input terminals. Ensure the total open-circuit voltage of the solar array does not exceed 280VDC.
• Battery Connection: Connect the 24V battery bank to the battery terminals. Observe correct polarity (+ to + and - to -).
• AC Input: Connect the utility grid or generator AC power to the AC input terminals.
• AC Output: Connect your loads to the AC output terminals.

4.3 Recommended Cable Sizing and Breakers

Note: Generator AC and Utility power AC cannot be used simultaneously as primary input sources.

5. Operating Instructions

The inverter features a glass-top LCD display and function buttons for monitoring and configuration.

5.1 LCD Display and Buttons

The LCD displays real-time system status, input/output voltages, charging current, and battery status. Use the function buttons to navigate menus and adjust settings.

5.2 Energy Source Priority Configuration

You can configure the inverter's energy source priority via the LCD. Common settings include:

• Solar First: Solar energy charges the battery as the first priority. Utility power charges the battery only when solar energy is unavailable.
• Solar and Utility: Solar energy and utility power charge the battery simultaneously.
• Only Solar Charging: Solar energy is the only charger source, regardless of utility availability.

6. Maintenance

Regular maintenance ensures the longevity and optimal performance of your inverter.

• Cleaning: Keep the inverter's exterior clean and free from dust. Use a dry, soft cloth. Do not use liquid cleaners.
• Ventilation: Periodically check that the cooling fans and ventilation openings are clear of obstructions.
• Connections: Annually inspect all electrical connections (PV, battery, AC input/output) for tightness and signs of corrosion. Tighten as necessary.
• Environment: Ensure the installation environment remains within specified temperature and humidity ranges.

7. Troubleshooting

If you encounter issues with your inverter, perform the following basic checks:

• No Power/Display Off: Check all power connections (battery, PV, AC input). Ensure the battery is charged and the main power switch is on.
• No AC Output: Verify that the inverter is turned on and not in an error state. Check for overload conditions or short circuits on the output.
• Error Codes: Refer to the LCD display for any error codes. Consult the full product manual (if available) for specific error code meanings.
• Overheating: Ensure adequate ventilation and that cooling fans are operating. Clear any obstructions around the unit.

If problems persist after performing these checks, contact customer support for assistance.
