5. Stiùireadh Sàbhailteachd
- Ensure all connections are tight and secure to prevent loose connections that can cause excessive heat.
- Ceangail am bataraidh ris an rianadair cosgais an-còmhnaidh, an uairsin ris a’ phannal grèine, agus mu dheireadh ris an luchd. Dì-cheangail san òrdugh eile.
- Do not connect an inverter directly to the load terminals of the charge controller. Connect inverters directly to the battery.
- Stàlaich an rianadair ann an àite le deagh fhionnarachadh, air falbh bho sholas dìreach na grèine, teòthachd àrd, agus taiseachd.
- Dèan cinnteach gu bheil an siostam voltage (12V or 24V) matches the battery bank voltage. The controller automatically detects this.
- Use appropriate wire gauges for all connections to prevent voltage tuiteam agus cus teasachadh.
- Cuir ort dìon-sùla nuair a bhios tu ag obair le bataraidhean.
6. Stàladh (Suidheachadh)
Follow these steps for proper installation of your solar charge controller.
- Stàladh: 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.
- Ceangail am bataraidh: 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.
- Ceangail am Pannal 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.
- Ceangail an Luchd: 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.

Figear 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. Obrachadh
Once installed, the controller operates automatically. The LCD display provides real-time information about your system.
7.1 Taisbeanadh LCD agus Gnìomhan Putan
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).
- Pàipearan-naidheachd goirid: Cycles through display parameters.
- Long Press (approx. 5 seconds): Enters or exits setting mode for load control.
7.2 Smachd luchdan
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.

| Trioblaid | Adhbhar a dh’fhaodadh a bhith ann | Fuasgladh |
|---|---|---|
| Controller not powering on / LCD blank | Battery not connected or reverse polarity; battery voltage ro ìosal. | Thoir sùil air ceanglaichean is pòlarachd a’ bhataraidh. Dèan cinnteach gu bheil meud a’ bhataraidh ceart.tage is above the minimum operating voltage (mar as trice 8V). |
| Bataraidh nach eil a’ cur cosgais | 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. |
| Luchdaich gun obair | 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. |
| Error codes on 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). |
