- Рамна монтажа: Use the included bracket to mount the controller on a surface.
Ensure adequate space around the controller for air circulation to prevent overheating.
3.2 Приклучоци за жици
Follow the correct wiring sequence to prevent damage to the controller or battery:
- Поврзете ја батеријата: First, connect the battery to the controller's battery terminals (7). Ensure correct polarity (positive to positive, negative to negative). The LCD will power on.
- Поврзете го соларниот панел: Next, connect the solar panel to the controller's solar terminals (8). Ensure correct polarity.
- Поврзете го DC оптоварувањето: Finally, connect your DC loads to the controller's load terminals (6). Ensure correct polarity.
Редослед на исклучување: To disconnect the system, reverse the order: disconnect the load, then the solar panel, and finally the battery.
This wiring diagram illustrates the proper connection order for the solar panel, battery, and DC load to the HQST solar charge controller.
When connecting wires, ensure they are inserted into the correct square socket for the cable, not the screw hole. Fully unscrew the terminal screws, insert the wire ends, then tighten the screws securely.
3.3 Поставување на типот на батерија
The controller automatically recognizes 12V/24V Sealed (AGM), Gel, and Flooded batteries. For Lithium batteries, manual parameter setting is required:
The LCD display allows for manual adjustment of battery parameters, especially crucial for Lithium-ion batteries.
- Press and hold the 'Up & Down' button to enter the setting mode.
- Use the 'Up & Down' buttons to navigate to the battery type setting (e.g., "b01" for Gel, "b02" for Sealed, "b03" for Flooded, "b04" for Lithium).
- For Lithium batteries, further adjust charging voltage, волумен на прекумерно празнењеtage, and other parameters as per your battery manufacturer's specifications.
- Press and hold the 'Load' button to save the settings and exit.
4. Упатства за работа
4.1 Навигација со LCD дисплеј
The LCD screen provides real-time monitoring of your solar system:
The intuitive LCD screen cycles through various operational data, including battery voltage, PV волtage, charge current, load current, controller temperature, and battery state of charge (SOC).
- Press the 'Up & Down' button (2) to manually cycle through the displayed parameters.
- The display will automatically cycle through parameters if no button is pressed for a few seconds.
4.2 Контрола на оптоварување
The controller features a DC load output with multiple control modes:
- Press the 'Load' button (4) to manually turn the DC load output on or off.
- The controller supports 17 different load control modes, allowing for customized operation (e.g., dusk-to-dawn, timed operation). Refer to the full manual for detailed instructions on setting load modes.
4.3 USB порта за полнење
The integrated 5V 1A USB port (1) can charge small electronic devices. This port is active when the DC load output is enabled.
4.4 4-Сtagд Паметно полнење
The controller employs an advanced 4-stagе-алгоритам за полнење за оптимизирање на здравјето и животниот век на батеријата:
This graph illustrates the voltagе и тековната проfiles during the 4-stage charging process, including Bulk, Boost/Absorption, Float, and Equalization stagес.
- Масовно полнење: Delivers maximum current to rapidly charge the battery.
- Boost/Absorption Charge: Одржува константен волуменtage to ensure the battery is fully charged without overcharging.
- Полнење на плови: Го намалува волуменотtage на пониско ниво за да се одржи батеријата целосно наполнета, компензирајќи за самопразнењето.
- Наплата за изедначување: (For lead-acid batteries only) Periodically overcharges the battery to balance cell voltagи спречува сулфација.
5. Одржување
To ensure the longevity and optimal performance of your HQST solar charge controller, perform the following maintenance checks:
- Редовна инспекција: Periodically check all wiring connections for tightness and signs of corrosion. Loose connections can cause voltagкапки и прегревање.
