5. Инструкции за безбедност
- Ensure all connections are tight and secure to prevent loose connections that can cause excessive heat.
- Секогаш прво поврзувајте ја батеријата со контролерот за полнење, потоа соларниот панел и на крај со товарот. Исклучете ја по обратен редослед.
- Do not connect an inverter directly to the load terminals of the charge controller. Connect inverters directly to the battery.
- Инсталирајте го контролерот во добро проветрено место, подалеку од директна сончева светлина, високи температури и влага.
- Обезбедете системот voltage (12V or 24V) matches the battery bank voltage. The controller automatically detects this.
- Use appropriate wire gauges for all connections to prevent voltagпад и прегревање.
- Носете заштита за очи кога работите со батерии.
6. Инсталација (Поставување)
Следете ги овие чекори за правилна инсталација на вашиот соларен контролер за полнење.
- Монтирање: 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.
- Поврзете ја батеријата: 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.
- Поврзете го соларниот панел: 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.
- Поврзете го товарот: 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.

Слика 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. Операција
Once installed, the controller operates automatically. The LCD display provides real-time information about your system.
7.1 LCD екран и функции на копчињата
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).
- Кратко притиснете: Cycles through display parameters.
- Долго притискање (приближно 5 секунди): Enters or exits setting mode for load control.
7.2 Контрола на оптоварување
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.

| Проблем | Можна причина | Решение |
|---|---|---|
| Контролерот не се вклучува / LCD екранот е празен | Battery not connected or reverse polarity; battery voltagе премногу ниско. | Проверете ги приклучоците и поларитетот на батеријата. Проверете го волуменот на батеријатаtage е над минималниот работен волуменtage (обично 8V). |
| Батеријата не се полни | 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. |
| Товарот не работи | 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. |
| Кодови за грешка на LCD-екранот | 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). |
