4. Configuració i instal·lació

Follow these steps for proper installation of your ECTIVE SC 20 SILENT solar charge controller:

1. Muntatge: Choose a suitable location for mounting the controller. It should be close to the battery, in a dry, cool, and well-ventilated area. Ensure there is sufficient space around the controller for air circulation, especially for the heat sink fins.
2. Connexió de la bateria: Connecteu primer la bateria al controlador. Assegureu-vos de la polaritat correcta (+ a + i - a -). El controlador detectarà el volum de la bateria.tage (12V or 24V) automatically. Use appropriate cable size for the current.
3. Connexió del panell solar: Connect the solar panels to the controller. Again, ensure correct polarity. The controller will begin charging once the solar panels are connected and producing power.
4. Connexió de càrrega (opcional): If your system includes a DC load directly connected to the controller, connect it last. Ensure the load current does not exceed the controller's rated load current.
5. Sensor de temperatura (opcional): If using an external temperature sensor (ECTIVE TS 1), connect it to the designated port on the controller. This improves charging accuracy by compensating for battery temperature.

Important: Always connect the battery first and disconnect the solar panel first when disassembling the system.

5. Instruccions de funcionament

Once installed, the ECTIVE SC 20 SILENT operates automatically. It utilizes MPPT technology to optimize power extraction from your solar panels and charges your batteries according to a sophisticated 3-stage charger profile:

• MPPT Charge: En aquest stage, the controller actively tracks the maximum power point of the solar array to deliver the most current possible to the battery. This continues until the battery voltage arriba a l'impuls voltage.
• Augment de la càrrega: Once the battery reaches the boost voltage, the controller maintains a constant voltage to prevent overcharging and excessive gassing. This stage ensures the battery is fully charged.
• Maintenance Charge (Float): After the boost charge, the controller reduces the voltage to a lower float voltage. Aquest stage maintains the battery at full capacity and compensates for self-discharge, allowing consumers to draw power simultaneously.
• Equalization Charge (for certain battery types): If the controller detects that the battery is excessively discharged, it may activate an automatic equalization charge for 120 minutes. This helps to balance cell voltages and improve battery life for specific battery types.

The controller's passive cooling system ensures silent operation, making it ideal for sensitive environments.

Monitoring with the App (Optional)

For real-time data and advanced monitoring, the ECTIVE SC 20 SILENT can be connected to a compatible app via the optional BT1 Bluetooth module (ASIN: B09FQ6X5N7). The app is available for Android and iOS devices.

6. Manteniment

The ECTIVE SC 20 SILENT is designed for minimal maintenance. However, regular checks can ensure optimal performance and longevity:

• Inspecció visual: Periodically inspect the controller and all connections for any signs of damage, corrosion, or loose wiring.
• Neteja: Ensure the heat sink fins are free from dust and debris to maintain efficient passive cooling. Use a soft, dry cloth for cleaning.
• Connexions: Verify that all terminal connections are secure. Loose connections can lead to power loss or overheating.
• Salut de la bateria: Monitor your battery's health and electrolyte levels (for flooded batteries) as per the battery manufacturer's recommendations.

Caution: Before performing any maintenance, disconnect all power sources (solar panels and battery) from the controller.
