The Projoy PEJB-1-1 photovoltaic combiner box connects PV modules in off-grid or grid-connected systems. It protects PV strings against short circuits and allows them to be disconnected for inspection, maintenance or repair.

The outdoor enclosure has an IP65 rating and surge protection. Cables are connected using MC4 connectors, and their cross-section must be sized to match the current of the PV array.
