2. Instruccions de seguretat
Si us plau, llegiu atentament totes les instruccions abans de la instal·lació i el funcionament. Si no seguiu aquestes instruccions, podeu patir danys a la unitat, lesions personals o danys materials.
- Ensure all connections are tight and correct to avoid excessive voltage drop and potential hazards.
- Install the controller indoors, away from direct sunlight, high temperatures, and moisture.
- The controller generates heat during operation; ensure adequate ventilation.
- Connect the battery first, then the solar panel, and finally the load. Disconnect in the reverse order: load, solar panel, then battery.
- Do not connect any inverter directly to the load terminals of the controller.
- Ensure the solar panel's open-circuit voltage (Voc) does not exceed the controller's maximum input voltage.
- Use appropriate circuit breakers or fuses for the battery and solar panel circuits.
- Keep children away from the solar power system.
- No intenteu desmuntar ni reparar el controlador vosaltres mateixos. Poseu-vos en contacte amb personal qualificat per al servei tècnic.
