4. Impostazione

Follow these steps for proper installation of your HQST MPPT Solar Charge Controller:

  1. Montaggio: Choose a dry, well-ventilated location away from direct sunlight and heat sources. Ensure adequate space around the controller for air circulation. The controller dimensions are approximately 5.91" x 2.42" x 4.16" (L x W x H).
  2. Collegamento della batteria: Connect the battery cables to the battery terminals on the charge controller. Ensure correct polarity (positive to positive, negative to negative). This connection must be made first.
  3. Connessione al pannello solare: Connect the solar panel cables to the solar panel terminals on the charge controller. Ensure correct polarity.
  4. Collegamento del carico (facoltativo): Se si utilizza un carico CC direttamente dal controller, collegare i cavi del carico ai terminali del carico. Assicurarsi della corretta polarità.
  5. Sensore di temperatura (opzionale): Connect the external temperature sensor to the designated interface. This allows for temperature compensation of battery charging voltage.
  6. Remote Meter (Optional): Connect the remote meter (RM-6) to the communication interface for external display and control.

Note: The solar panel, battery, adapter kit, tray cables, DC load, and power inverter are not included with the charge controller.

5. Operativo

Once installed, the controller will automatically detect the system voltage (12V or 24V). The LCD display provides real-time information about your system's performance.

5.1. Selezione del tipo di batteria

The controller is compatible with various battery types. To select or customize the battery type:

  • Access the settings menu via the operation keys on the controller or the remote meter.
  • Navigate to the battery type setting.
  • Select from pre-set options (Sealed, Vented, Colloidal, Lithium) or enter 'User' mode to set custom charging parameters.

5.2. Carica Stages

Il controller utilizza un 5-stagAlgoritmo di ricarica per ottimizzare la durata e le prestazioni della batteria:

  1. Ricarica rapida: Initial bulk charging phase.
  2. Holding Charge: Absorption phase, maintaining a constant voltage.
  3. Carica potenziata: Raises voltage per garantire la carica completa.
  4. Carica galleggiante: Maintains battery at a full state of charge.
  5. Equalization (for lead-acid batteries only): Sovraccarichi periodici per bilanciare il volume della cellatages.
