  • Always connect the solar panels and load after the battery.
  • Disconnect the solar panels and load before disconnecting the battery.
  • Install the controller in a well-ventilated, dry, and cool environment, away from flammable materials.
  • Avoid touching or short-circuiting wires or terminals.
  • Utilizzare cavi di sezione adeguata per tutti i collegamenti per evitare il surriscaldamento.
  • This device is for indoor use only. Avoid exposure to water or excessive humidity.
  • Tenere fuori dalla portata dei bambini.

4. Installazione

4.1 Sequenza di cablaggio

  1. Connect the battery to the charge controller. Ensure correct polarity (+ to + and - to -). The controller will display the battery voltage.
  2. Connect the solar panel to the charge controller. Ensure correct polarity. The controller will begin charging the battery.
  3. Connect the load to the charge controller. Ensure correct polarity.

Importante: Always connect the battery first and disconnect it last. This sequence prevents damage to the controller from voltage picchi.

4.2 Montaggio

Mount the controller vertically on a wall or flat surface in a well-ventilated area, away from direct sunlight, high temperatures, and water. Ensure there is sufficient air circulation around the heat sink.

Display LCD e pulsanti 5.1

The controller features an LCD display and three buttons for operation: UP, DOWN, and SET.

  • Pulsante SU: Navigates through display interfaces, increases parameter values.
  • Pulsante GI: Navigates through display interfaces, decreases parameter values.
  • Pulsante IMPOSTA: Enters/exits setting mode, confirms parameter changes.

5.2 Browsing Display Interfaces

Press the UP or DOWN button to cycle through various display interfaces, including battery voltage, charging current, accumulated discharge, and load status.

5.3 Impostazioni dei parametri

To enter the setting interface, long-press the SET button for 5 seconds. Use the UP and DOWN buttons to adjust values and the SET button to confirm and move to the next parameter. Long-press SET again to save changes and exit.

I parametri regolabili includono:

  • Tipo di batteria: Select the correct battery type (e.g., Lead-Acid, Lithium).
  • Modalità di controllo del carico: Set timer for load operation (e.g., 24H for continuous, 16H for dusk-to-dawn).
  • Volume di caricatage: Adjust maximum charge voltage.
  • Volume di interruzione dello scaricotage: Imposta il volume minimotage before load disconnection.
  • Scarica Ricollega Voltage: Imposta il volumetage at which the load reconnects.

Refer to the "Specifications" section for default and adjustable ranges for each parameter.
