5. Uppsetningarleiðbeiningar
Follow these steps for proper installation of your SolarX 4K MPPT Solar Charge Controller:
- Upptaka: Fjarlægið alla íhluti varlega úr umbúðunum og athugið hvort þeir séu skemmdir.
- Uppsetning: Choose a suitable location for mounting the controller. Ensure it is in a well-ventilated area, protected from direct sunlight and moisture. Use the provided fixing screws and anchors to securely mount the unit.
- Jarðtenging: Connect the grounding screw to a reliable earth ground using appropriate wiring.
- Tenging sólarplötu: Connect your solar panels to the input terminals of the SolarX 4K. Ensure correct polarity (+ to + and - to -) and that the total open-circuit voltage of your solar array is within the controller's specified input range (150V-500V).
- Battery/Generator Connection: Connect the DC output cable (XT60-F connectors) from the SolarX 4K to your compatible BLUETTI solar generator or battery (e.g., Apex 300, B300K). Ensure a secure connection. For optimal 4kW output performance, use with BLUETTI Apex 300 & B300K systems and a P090A cable.
- Upphafsvirkjun: Once all connections are secure, power on your BLUETTI solar generator or battery. The SolarX 4K will automatically detect the solar input and begin charging.
