Array Junction Box

Array Junction Boxes (AJB), also referred to as PV combiner boxes, it collects DC power from PV strings with blocking diodes on each string for protecting panels from reverse current flow. The collected power is then transferred to inverter to be converted into AC.A junction box is an electrical enclosure that houses one or more wiring connections. The box protects the connections, which usually contain vulnerable points such as wire splices, from environmental conditions and accidental contact.
