3. Safety Information

WARNING: Improper installation or operation can lead to serious injury or damage to the equipment. Always follow safety guidelines.

• Ensure the battery is at least 60% charged before connecting to the controller.
• Always connect the battery to the controller FIRST.
• NEVER connect your solar panel array to the controller without a battery connected.
• Ensure your input power and voltage do not exceed the maximum ratings specified in the specifications section.
• The controller provides protection against overcharge, overdischarge, overload, overheat, reverse polarity, and lightning. However, proper installation is crucial for these features to function effectively.
• Do not connect inverters/inductive loads directly to the controller's load port.

4. Package Contents

Upon opening the package, please verify that all items are present and undamaged:

• 1 x MPPT Solar Charge Controller (P60A)
• 1 x Temperature sensor
• 1 x User Manual (English)

5. Installation and Wiring

Follow these steps carefully for proper installation:

1. **Prepare Wires:** Turn the adjusting screw counterclockwise on the terminal block until the plate moves downward. Peel off the insulation coating of the cable tip by about 8 to 10 mm.
2. **Connect Battery:** Insert the prepared wire into the new opening between the plate and the "top" of the terminal hole. Turn the adjuster clockwise; the plate moves upward and crushes the wire in the hole of the terminal. Ensure all connections are tight. Always connect the battery first.
3. **Connect Solar Panels:** After the battery is securely connected, connect the solar panel array to the designated terminals. Ensure correct polarity.
4. **Connect Load:** Finally, connect your DC loads to the load terminals.
5. **Verify Connections:** Double-check all connections for tightness and correct polarity before powering on the system.

IMPORTANT NOTE:

• Make sure your battery must be at least 60% charged prior to connecting to controller.
• Always connect your battery first.
• Never connect your solar panel array to the controller without a battery.
• Careful your input power and voltage does not exceed the max.

6. Operating Instructions

6.1 LCD Display Interface

The controller features a blacklight LCD display that shows various real-time data and working conditions. The display provides information such as PV voltage, battery voltage, load current, charging status, and more.

Key indicators on the LCD:

• **1. Charging failure:** Indicates an issue with the charging process.
• **2. Charging logo:** Shows when the battery is being charged.
• **3. Solar panels:** Displays solar panel status.
• **4. Solar panel voltages and currents:** Real-time readings from the PV array.
• **5. Battery voltage and current:** Real-time battery status.
• **6. Evening System Status:** Indicates system status during evening hours.
• **7. Load stops working hours:** Displays the duration the load has been off.
• **8. Charging stops voltage:** The voltage at which charging ceases.
• **9. Ambient temperature and battery capacity percentage:** Environmental temperature and battery charge level.
• **10. Discharge stop voltage:** The voltage at which discharge to load ceases.
• **11. Discharge identity / Discharge fault:** Indicates load discharge status or issues.
• **12. Load and state:** Shows load status (ON/OFF).
• **13. Load voltage and current:** Real-time readings for the connected load.
• **14. Dawn System Status:** Indicates system status during dawn hours.
• **15. Undervoltage restore voltage:** The voltage at which the load will be reconnected after undervoltage protection.

Note: The cumulative power generation KHW of the solar power system is shown in position 9. After the battery is disconnected, the power generation KWH is cleared.

6.2 Control Buttons

The controller has several buttons for navigation and control:

• **Toggle Key:** Used to cycle through different display parameters (PV OFF → LOAD OFF → LOAD ON → Evening → Interval → Dawn). This button also allows setting the order of the automatic cycle.
• **'+' (Plus) Key:** Used to increase values when setting parameters.
• **'-' (Minus) Key:** Used to decrease values when setting parameters.
• **Manual Switch Load Key:** This button can be used to manually open or close the load.
• **5S Reset:** Press and hold the reset button for 5 seconds to restore factory settings.

All the various real-time data is shown on one display, making it convenient for the user to check.

7. Maintenance

To ensure optimal performance and longevity of your MPPT Solar Charge Controller, regular maintenance is recommended:

• **Cleanliness:** Keep the controller clean and free from dust and debris. Ensure the cooling vents are not obstructed to allow for proper heat dissipation.
• **Connections:** Periodically check all wiring connections (solar panels, battery, load) to ensure they are tight and free from corrosion. Loose connections can lead to power loss or damage.
• **Environment:** Ensure the controller is installed in a dry, well-ventilated area, away from direct sunlight and extreme temperatures.
• **Battery Health:** Monitor your battery's health and ensure it is compatible with the controller's charging profiles.
