2. Bezpečnostní opatření

• Ensure all wiring is correctly connected before powering on the controller. Incorrect wiring can damage the device or connected components.
• Vždy nejprve připojte baterii, poté solární panel a nakonec zátěž. Odpojení provádějte v opačném pořadí.
• The controller is designed for 12V/24V lead-acid batteries (GEL, FLOODED, SLD). Do not use with other battery types unless specified.
• Install the controller in a well-ventilated, dry environment, away from direct sunlight and moisture.
• Nepokoušejte se rozebírat ani opravovat ovladač sami. Pro servis kontaktujte kvalifikovaný personál.
• Ensure the solar panel's open-circuit voltage (Voc) does not exceed the controller's maximum input voltage.

3. Vlastnosti produktu

• Automatická identifikace napětí systému 12V/24Vtage.
• PWM charging mode for efficient battery charging.
• Built-in LCD display for clear status indication and parameter adjustment.
• Dual USB outputs (max 2.5A) for charging mobile devices.
• Comprehensive protection functions: overcharge, over-discharge, overload, short circuit, reverse polarity.
• Automatic memory data storage.
• One-key operation for all settings.

4. Nastavení a instalace

Follow these steps carefully to install your solar charge controller:

1. Příprava zapojení: Ensure all wires are properly sized for your system's current and voltage. Strip wire ends approximately 8-10mm.
2. Připojte baterii: Connect the battery to the controller's battery terminals (marked with a battery symbol). Ensure correct polarity (+ to + and - to -). The LCD will light up.
3. Připojte solární panel: Connect the solar panel to the controller's solar panel terminals (marked with a solar panel symbol). Ensure correct polarity.
4. Připojení zátěže: Připojte stejnosměrnou zátěž ke svorkám zátěže regulátoru (označené symbolem žárovky). Dbejte na správnou polaritu.

Important: Always connect the battery first, then the solar panel, and finally the load. Disconnect in the reverse order: load, then solar panel, then battery.
