5. Saugos instrukcijos
- Ensure all connections are tight and secure to prevent loose connections that can cause excessive heat.
- Visada pirmiausia prijunkite akumuliatorių prie įkrovimo valdiklio, tada saulės bateriją ir galiausiai apkrovą. Atjunkite atvirkštine tvarka.
- Do not connect an inverter directly to the load terminals of the charge controller. Connect inverters directly to the battery.
- Valdiklį montuokite gerai vėdinamoje vietoje, atokiau nuo tiesioginių saulės spindulių, aukštos temperatūros ir drėgmės.
- Įsitikinkite, kad sistemos ttage (12V or 24V) matches the battery bank voltage. The controller automatically detects this.
- Visoms jungtims naudokite tinkamo skersmens laidus, kad išvengtumėte įtampos kritimo.tage lašas ir perkaitimas.
- Dirbdami su baterijomis, dėvėkite akių apsaugos priemones.
6. Įdiegimas (sąranka)
Norėdami tinkamai įdiegti saulės baterijų įkrovimo valdiklį, atlikite šiuos veiksmus.
- Montavimas: 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.
- Prijunkite akumuliatorių: 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.
- Prijunkite saulės kolektorių: 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.
- Prijunkite apkrovą: 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.

7. Operacija
Once installed, the controller operates automatically. The LCD display provides real-time information about your system.
7.1 LCD ekranas ir mygtukų funkcijos
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).
- Trumpas paspaudimas: Cycles through display parameters.
- Long Press (approx. 5 seconds): Enters or exits setting mode for load control.
7.2 Apkrovos valdymas
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 | Galima priežastis | Sprendimas |
|---|---|---|
| Valdiklis neįsijungia / LCD ekranas tuščias | Baterija neprijungta arba atvirkštinis poliškumas; baterijos įtampatage per žema. | Patikrinkite akumuliatoriaus jungtis ir poliškumą. Įsitikinkite, kad akumuliatoriaus įtampatage yra didesnis nei minimalus darbinis tūristage (paprastai 8 V). |
| Akumuliatorius neįkraunamas | 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. |
| Įkrova neveikia | 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. |
| Klaidų kodai LCD ekrane | 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). |
