4. Maintenance Features

The Vechline 1012/2024 series PWM Solar Charge Controller is an advanced digital device designed for managing solar power systems. It operates fully automatically and is suitable for extreme environments due to its robust design and IP67 protection.

Function Description

The primary function of this controller is to regulate the charging of batteries from solar modules using Pulse Width Modulation (PWM) technology. This method is highly efficient, extending battery life and improving overall solar system performance. The controller also manages the load connected to the system, offering various operational modes.

Key protective features include:

• Electronic protection: Safeguards against overcharging, over-discharging, overload, short circuits, and reverse polarity from the solar module.
• Automatic day/night recognition: The controller automatically detects day and night conditions to manage load operation.

Usage Features

The controller features an industrial design, making it suitable for a wide range of applications. User interaction is simplified through a single-key operation and a digital tube display for settings.

Indicators and Operations:

• Charging Status LED:
  • Green (Solid): Normal charging.
  • Green (Fast Flashing): Over voltage.
• Battery Status LED:
  • Green (Solid): Normal battery status.
  • Green (Slowly Flashing): Battery full.
  • Orange (Solid): Under voltage.
  • Red (Solid): Over discharged.
• Radix Point of Digital Tube (Load indicator):
  • Red (Solid): Load ON.
  • Red (Slowly Flashing): Over Load.
  • Red (Fast Flashing): Short Circuit.

Load Work Modes: The digital tube displays the load work mode, which can be configured using a single key.

• Manual Control: Allows manual switching of the load ON/OFF via the button.
• Light ON/OFF: The load turns on at night and off during the day.
• Light ON + Timer: The load turns on at night and stays on for a specified duration (1-13 hours).
• Test Mode (Default): Similar to Light Control Mode but without the 10-minute delay.

Configuration Method:

1. To enter configuration mode, disconnect the PV or connect the PV (Voltage<5V) until the digital tube point illuminates. It will turn off if PV voltage is >6V.
2. The key can be used to switch the load ON/OFF (manual control) or clear faults.
3. Press and hold the button for over 5 seconds to enter browsing mode. Click the button to cycle through parameters.
4. Release the key when the desired value is displayed. After 15 seconds, the digital tube will stop flashing, and the setting will be saved.

Mounting:

1. Connect components in the specified sequence: always connect the battery first, paying attention to polarity (+ and -).
2. After connecting the battery, check if the battery indicator is green. If not, troubleshoot according to chapter 4.
3. Install the battery fuse as close to the battery as possible, ideally within 150mm.

Maintenance Features

The controller is designed for reliability, but troubleshooting steps are provided for common issues:

• Charging LED off during daytime (PV array disconnection): Check PV and battery wire connections for correctness and tightness.
• Battery indicator green fast flashing (Battery voltage higher than over voltage disconnect):
  1. Disconnect the solar array and measure battery voltage.
  2. Consider changing the controller or battery if issues persist.
• Battery LED indicators red and loads not working (Battery over discharged): The controller automatically cuts off output. The LED indicator will return to green once the battery is fully charged.
• Radix point of digital tube fast flashing and load not working (Short circuit): Clear the short circuit. Reactivation occurs after a 10-second delay for the first instance. For subsequent occurrences, press the key to clear the error, and the controller will resume operation after 3 seconds or a restart.
• Radix point of digital tube slowly flashing and load not working (Over load): Reduce the number of electric equipment. If load power exceeds 1.25-1.5 times, 1.5-2 times, or 2 times the nominal value, the controller will automatically close loads in 60, 5, or 1 second, respectively. Press the key to clear the error, and the controller will resume operation after 3 seconds or a restart.

Warranty Disclaimer: The warranty does not cover damages resulting from improper use, unsuitable environment, exceeding rated current/voltage/power, operating outside specified temperature limits, unauthorized disassembly/repair, or damage due to natural elements (e.g., lightning) or during transportation/shipment.
