5. Istruzzjonijiet tas-Sigurtà
- Kun żgur li l-konnessjonijiet kollha huma ssikkati u siguri biex tevita konnessjonijiet maħlula li jistgħu jikkawżaw sħana eċċessiva.
- Always connect the battery to the charge controller first, then the solar panel, and finally the load. Disconnect in the reverse order.
- Do not connect an inverter directly to the load terminals of the charge controller. Connect inverters directly to the battery.
- Install the controller in a well-ventilated area, away from direct sunlight, high temperatures, and moisture.
- Tiżgura s-sistema voltage (12V or 24V) matches the battery bank voltage. The controller automatically detects this.
- Use appropriate wire gauges for all connections to prevent voltage qatra u sħana żejda.
- Ilbes protezzjoni għall-għajnejn meta taħdem bil-batteriji.
6. Installazzjoni (Setup)
Segwi dawn il-passi għall-installazzjoni xierqa tal-kontrollur tal-iċċarġjar solari tiegħek.
- Immuntar: 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.
- Qabbad il-batterija: 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.
- Qabbad il-Panel Solari: 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.
- Qabbad it-Tagħbija: 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. Operazzjoni
Once installed, the controller operates automatically. The LCD display provides real-time information about your system.
7.1 Funzjonijiet tal-Wiri LCD u tal-Buttuni
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).
- Stampa qasira: Cycles through display parameters.
- Agħfas fit-tul (madwar 5 sekondi): Enters or exits setting mode for load control.
7.2 Kontroll tat-Tagħbija
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.

| Problema | Kawża Possibbli | Soluzzjoni |
|---|---|---|
| Controller not powering on / LCD blank | Batterija mhux imqabbda jew polarità maqluba; volum tal-batterijatage baxx wisq. | Iċċekkja l-konnessjonijiet u l-polarità tal-batterija. Kun żgur li l-vultaġġ tal-batterijatage huwa ogħla mill-volum minimu operattivtage (tipikament 8V). |
| Il-batterija mhix qed tiċċarġja | Solar panel not connected or reverse polarity; insufficient sunlight; damaged solar panel or wiring. | Check solar panel connections and polarity. Ensure adequate sunlight. Inspect solar panel and wiring for damage. |
| It-tagħbija mhux qed taħdem | Load not connected or reverse polarity; load current exceeds controller rating; battery voltage too low; load control setting. | Check load connections and polarity. Ensure load current is within 20A. Check battery voltage. Adjust load control settings if a timer or light sensor mode is active. |
| Kodiċijiet ta' żball fuq l-LCD | Specific system fault (e.g., overcharge, over-discharge, short circuit). | Refer to the controller's internal error code list (if available in a more detailed manual) or contact HQST support. Address the underlying issue (e.g., reduce load, check battery). |
