5. Instrucțiuni de siguranță

• Ensure all connections are tight and secure to prevent loose connections that can cause excessive heat.
• Conectați întotdeauna mai întâi bateria la regulatorul de încărcare, apoi la panoul solar și în final la sarcină. Deconectați în ordine inversă.
• Do not connect an inverter directly to the load terminals of the charge controller. Connect inverters directly to the battery.
• Instalați controlerul într-o zonă bine ventilată, ferită de lumina directă a soarelui, temperaturi ridicate și umiditate.
• Asigurați-vă că sistemul voltage (12V or 24V) matches the battery bank voltage. The controller automatically detects this.
• Use appropriate wire gauges for all connections to prevent voltagpicătură și supraîncălzire.
• Purtați ochelari de protecție atunci când lucrați cu baterii.

6. Instalare (Configurare)

Follow these steps for proper installation of your solar charge controller.

1. Montare: Choose a dry, well-ventilated location for mounting the controller. Ensure there is sufficient space around the controller for heat dissipation. Use the mounting holes provided on the unit.
2. Conectați bateria: Connect the battery to the battery terminals on the charge controller. Ensure correct polarity (+ to + and - to -). The LCD display should illuminate, indicating the controller has detected the battery voltage.
3. Conectați panoul solar: Connect the solar panel to the solar panel terminals on the charge controller. Ensure correct polarity. The controller will begin charging the battery if sunlight is available.
4. Conectați sarcina: Connect your DC loads (e.g., lights, fans) to the load terminals. Ensure correct polarity. The USB-A port can also be used for charging compatible devices.

Important Connection Order: Always connect the battery first, then the solar panel, and finally the load. Disconnect in the reverse order: load first, then solar panel, then battery.

Figura 6.2: Visual step-by-step guide for connecting the HQST Solar Charge Controller: 1. Connect the battery. 2. Connect the solar panel. 3. Connect the load (light bulb). This sequence ensures safe and proper system setup.

7. Funcționare

Once installed, the controller operates automatically. The LCD display provides real-time information about your system.

7.1 Afișaj LCD și funcții ale butoanelor

The LCD cycles through various parameters such as battery voltage, charging current, load current, and temperature. The single red button is used to manually cycle through display modes or to enter settings for load control (e.g., timer settings for lights).

• Apăsare scurtă: Cycles through display parameters.
• Long Press (approx. 5 seconds): Enters or exits setting mode for load control.

7.2 Controlul sarcinii

The controller offers programmable load control. You can set the load to turn on/off based on daylight or a timer. Refer to the specific settings menu on the LCD for detailed configuration. The USB-A port is typically powered when the load output is active.
