4. Sąranka
Follow these steps for proper installation of your HQST MPPT Solar Charge Controller:
- Montavimas: Choose a dry, well-ventilated location away from direct sunlight and heat sources. Ensure adequate space around the controller for air circulation. The controller dimensions are approximately 5.91" x 2.42" x 4.16" (L x W x H).
- Baterijos prijungimas: Connect the battery cables to the battery terminals on the charge controller. Ensure correct polarity (positive to positive, negative to negative). This connection must be made first.
- Saulės skydo jungtis: Connect the solar panel cables to the solar panel terminals on the charge controller. Ensure correct polarity.
- Apkrovos jungtis (neprivaloma): If using a DC load directly from the controller, connect the load cables to the load terminals. Ensure correct polarity.
- Temperatūros jutiklis (pasirinktinai): Connect the external temperature sensor to the designated interface. This allows for temperature compensation of battery charging voltage.
- Remote Meter (Optional): Connect the remote meter (RM-6) to the communication interface for external display and control.

Note: The solar panel, battery, adapter kit, tray cables, DC load, and power inverter are not included with the charge controller.
5. Operacinis
Once installed, the controller will automatically detect the system voltage (12V or 24V). The LCD display provides real-time information about your system's performance.
5.1. Baterijos tipo pasirinkimas
The controller is compatible with various battery types. To select or customize the battery type:
- Access the settings menu via the operation keys on the controller or the remote meter.
- Navigate to the battery type setting.
- Select from pre-set options (Sealed, Vented, Colloidal, Lithium) or enter 'User' mode to set custom charging parameters.

5.2. Įkraunamas Stages
Valdiklis naudoja 5 stagįkrovimo algoritmas, skirtas optimizuoti akumuliatoriaus veikimo laiką ir našumą:
- Greitas įkrovimas: Initial bulk charging phase.
- Holding Charge: Absorption phase, maintaining a constant voltage.
- „Boost Charge“: Raises voltage, kad būtų užtikrintas visiškas įkrovimas.
- Plūdinis mokestis: Maintains battery at a full state of charge.
- Equalization (for lead-acid batteries only): Periodically overcharges to balance cell voltages.

6. Priežiūra
Reguliarus saulės įkrovimo valdiklio aptarnavimas užtikrina jo ilgaamžiškumą ir optimalų veikimą.
- Švara: Valiklį laikykite švarų, be dulkių ir šiukšlių. Valymui naudokite sausą šluostę.
- Jungtys: Periodiškai tikrinkite visas laidų jungtis, ar jos nėra sandarios ir ar nėra korozijos. Atsilaisvinusios jungtys gali perkaisti ir sukelti prastą veikimą.
- Vėdinimas: Įsitikinkite, kad ventiliacijos angos nėra užblokuotos, kad šiluma tinkamai išsisklaidytų.
- Akumuliatoriaus patikrinimas: Regularly inspect your batteries for any signs of damage, swelling, or leakage. Follow battery manufacturer's maintenance guidelines.
