2. Saugos priemonės

Please read all instructions and precautions in the manual before installation. Improper installation can lead to serious injury or damage to the device.

• Always connect the battery first to the charge controller to allow it to recognize the system voltage.
• Connect components to the charge controller in the sequence shown in the wiring diagram, paying close attention to the positive (+) and negative (-) terminals.
• Do not insert the fuse or turn on the breaker during the initial installation process.
• When disconnecting the system, reverse the connection order.
• The battery fuse should be installed as close to the battery as possible, ideally within 150mm.
• The VS AU series is a positive ground controller. Any positive connection of solar, load, or battery can be earth grounded as required.
• If an inverter or other load with a large start current is necessary, connect it directly to the battery rather than to the controller.

4. Sąranka ir diegimas

Follow these steps carefully to install your EPEVER Solar Charge Controller:

1. Pasiruoškite montavimui: Ensure all components are available and that you have the necessary tools. Do not insert the fuse or turn on any breakers at this stage.
2. Prijunkite akumuliatorių: Connect the battery to the charge controller first. This allows the controller to automatically detect the system voltage (12V or 24V). Ensure correct polarity (+ to + and - to -).
3. Install Battery Fuse: Install the battery fuse as close to the battery as possible, ideally within 150mm, for safety.
4. Prijunkite saulės kolektorių: Connect the solar panel(s) to the designated solar input terminals on the controller. Observe correct polarity.
5. Prijunkite apkrovą: Connect your DC loads (e.g., lights, fans) to the load output terminals. Ensure correct polarity.
6. Maitinimas: After all connections are secure and verified, you may insert the fuse and turn on any breakers. Check the LCD display on the controller to confirm it powers on.

Pastaba: For inverters or other loads with high starting currents, connect them directly to the battery, not through the controller's load terminals.

6. Priežiūra

Regular maintenance ensures the longevity and optimal performance of your solar charge controller system.

• Švara: Valiklį laikykite švarų, be dulkių ir šiukšlių. Valymui naudokite sausą šluostę.
• Jungtys: Periodically check all wiring connections to ensure they are tight and free from corrosion. Loose connections can cause overheating and poor performance.
• Vėdinimas: Ensure the controller has adequate ventilation to prevent overheating. Do not block the ventilation holes.
• Akumuliatoriaus patikrinimas: Regularly inspect your battery for any signs of damage, corrosion, or swelling. Ensure battery terminals are clean.
• Sistemos našumas: Monitor the LCD display regularly to ensure the system is operating within normal parameters. Note any unusual readings.

7. Problemų sprendimas

If you encounter issues with your EPEVER Solar Charge Controller, consider the following common problems and solutions:

• Valdiklis neįsijungia:
  • Check battery connections: Ensure the battery is connected first and with correct polarity.
  • Patikrinkite akumuliatoriaus tūrįtage: Ensure the battery has sufficient charge (above minimum operating voltagir).
  • Check fuse: Verify the battery fuse is intact and not blown.
• Be saulės įkrovimo:
  • Check solar panel connections: Ensure panels are connected correctly and securely to the controller.
  • Check solar panel output: Verify panels are receiving sunlight and producing voltage.
  • Check for shading: Ensure solar panels are not shaded.
• Įkrovimas neveikia:
  • Check load connections: Ensure loads are connected correctly to the controller's load terminals.
  • Check load control mode: Verify the load control mode is set appropriately (e.g., always on, dusk-to-dawn).
  • Patikrinkite akumuliatoriaus tūrįtage: jei akumuliatoriaus talpatage is too low, the controller may disconnect the load to protect the battery.
  • Check load current: Ensure the load current does not exceed the controller's maximum load current rating.
