Using this cable is easy. First, make sure your power station and solar panels are turned off. Then, connect one end of the MC4 Solar Extension Cable to the appropriate port on your solar panel and the other end to the MC4 to XT60 Solar Cable or your power station. When the connection is secure, you can turn on your equipment. As for maintenance, keep the cable away from sharp objects to avoid cuts and abrasions. Also, store it in a dry place when not in use. When handling the cable, don't bend it too sharply as this could damage the internal wires. If you notice any signs of wear or damage, stop using the cable immediately and replace it to ensure safety and proper functioning.
