AC Combiner Box

The main function is to aggregate the output of multiple solar panels into a unified power supply, which is then sent to the inverter. Circuit breaker: Disconnects a circuit in the event of a power surge or short circuit. Fuse: Isolates a problematic circuit in the event of an overload. Busbar: A wire that connects multiple wires, especially solar panels. Bridge rail: connects the circuit breaker and the fuse terminal. Enclosure: A physical box that houses all the components. Rapid shut-off device: A safety mechanism for quick closing of roof panels. DC Break: The switch interrupts the DC current. DC surge protector: Protects against power surges. DC Fuse Holder: The protective housing of the fuse. Capacity and configuration: Make sure it can accommodate the number of strings of the solar array. Protection features: Priority is given to boxes with overcurrent protection, surge protection, and rapid shutdown. Enclosure rating: Look for an IP65 rating or higher to ensure protection against dust and water.
