2. Informació i precaucions de seguretat
Please read all safety instructions carefully before installation and operation to prevent damage to the controller, battery, or other components.
- This solar charge controller is designed exclusively for bateries de plom-àcid (OPEN, AGM, GEL). Do not use it with other battery types, including lithium batteries or nickel-metal hydride batteries.
- The controller can only use photovoltaic panels as its power source. Do not use DC or other power sources as a power source.
- Ensure the battery has sufficient voltage for the controller to recognize its type (12V or 24V) during the first installation.
- Install the controller close to the battery to minimize voltage drop due to excessive wire length, which can affect accurate voltage detecció.
- The controller will generate heat during operation. Install it on a flat, well-ventilated surface to ensure proper heat dissipation.
- Always connect the components in the specified order to avoid damage.

4. Configuració i instal·lació
Follow these steps for proper installation of the solar charge controller. Ensure all connections are secure and correct to prevent damage.
- Prepareu la ubicació d'instal·lació: Choose a flat, well-ventilated surface near the battery. Avoid direct sunlight, high temperatures, and humid environments.
- Connecteu la bateria: Connect the positive and negative terminals of the battery to the corresponding battery terminals on the controller. The controller will automatically detect the battery voltage (12V or 24V). Ensure the battery has sufficient charge for detection.
- Connecteu el panell solar: Connect the positive and negative terminals of the solar panel to the corresponding solar panel terminals on the controller.
- Connect the Load: Connect the positive and negative terminals of your DC load to the corresponding load terminals on the controller. Be careful not to reverse the connections.
