Nastavení a instalace
- Montáž: Securely mount the controller in a well-ventilated area, away from direct sunlight and excessive heat sources. The aluminum casing acts as a heat sink.
- Sekvence zapojení:
- Connect the battery to the controller's output terminals first. Ensure correct polarity (red for positive, black for negative). The output voltage is adjustable between 10-30V.
- Connect the solar panel(s) to the controller's input terminals. Ensure correct polarity. The PV input voltage by mělo být mezi 18V-55V.
- Počáteční zapnutí: Once all connections are secure, the controller will power on. The LED display will show input and output voltage/current. The controller starts working when the input voltage je vyšší než 17V.
- Výstupní objemtage Úprava: Use the "OK", "+", and "-" buttons on the controller to set the desired output voltage for your battery type. Refer to your battery's specifications for the correct charging voltage.

Návod k obsluze
The controller operates automatically once properly connected and configured. It will track the maximum power point of the solar panel to ensure efficient charging.
Sledování:
The LED display shows real-time input voltage (V) and current (A) from the solar panel, and output voltage (V) and current (A) to the battery.
Nastavení výstupního objemutage:
Chcete-li upravit výstupní objemtage:
- Press the "OK" button to enter voltage režim nastavení.
- Use the "+" and "-" buttons to increase or decrease the target output voltage.
- Press "OK" again to confirm and save the setting.
The controller will automatically stop charging if the input voltage drops below 1.1 times the rated output voltage and the charging current is below the cut-off current.
Údržba
- Pravidelná kontrola: Pravidelně kontrolujte těsnost a korozi všech kabelových spojů.
- Čištění: Keep the controller's exterior clean and free of dust. Use a dry cloth for cleaning. Do not use harsh chemicals or abrasive cleaners.
- Větrání: Ensure the area around the controller remains clear to allow for proper heat dissipation from the heat sink fins.
- Podmínky prostředí: While the device is IP66 rated, prolonged exposure to extreme conditions outside its operating temperature range (-40℃ to +65℃) should be avoided.
Odstraňování problémů
- No display or power:
- Check battery connections and ensure they are secure and have sufficient voltage.
- Verify solar panel connections and ensure adequate sunlight for power generation (input voltag(např. > 17 V).
- Baterie se nenabíjí:
- Confirm solar panel input voltage je v rozsahu 18V-55V.
- Zkontrolujte výstupní objtage setting to ensure it matches the battery's charging requirements.
- Zkontrolujte veškeré zapojení, zda nejsou uvolněná nebo poškozená.
- Ensure the charging current is not below the cut-off current, which would cause the system to turn off charging.
- Ochrana proti přehřátí:
If the internal temperature exceeds 100°C, the controller will reduce output power. If it reaches 110°C, it will automatically shut off. Allow the unit to cool down. Ensure proper ventilation and ambient temperature.
- Ochrana proti zkratu:
In case of an output short circuit, the controller will automatically turn off the output. It will resume normal operation once the short circuit is removed.
