3. Cyfarwyddiadau Diogelwch

WARNING: Failure to follow these safety instructions may result in serious injury or damage to the product.

• Always connect the battery first. Ensure sufficient battery voltage for the controller to recognize the correct system voltage.
• NEVER connect the solar panel array to the controller without a battery connected.
• The disassembly sequence is contrary to the wiring order (disconnect solar, then battery, then load).
• DO NOT connect any inverter, wind turbine, alternator, or charger directly to the charge controller. Connect inverters directly to the battery.
• Sicrhau cyfaint mewnbwn solartage is at least 3V higher than the battery voltage and total input power is within the specified range.
• The charging indicator may turn on and off, and charging current may fluctuate on cloudy days or in low light conditions. This is normal operation.
• If the controller is buzzing, the fan is operating to dissipate heat. This is normal.
• DO NOT install the charging controller in direct sunlight to avoid power loss due to overheating.
• Ensure adequate ventilation around the controller (approx. 20cm space) for heat dissipation.
• Ensure all connections to and from the controller are tight.
• DO NOT allow the positive (+) and negative (-) terminals of the battery to touch each other.
