Phaesun JB Junction Boxes
The Phaesun PN-JB Junction Box is an electrical box to facilitate the parallel connection of several strings of a photovoltaic system.
Available in two versions, PN-JBI for industrial applications (telecom, cathodic protection…) and PN-JBW for water pumping applications, this product meets the requirements of solar systems in remote areas.
The lightning protection system is equipped with a device to prevent thermal runaway by temporary disconnection in case of activation. The PN-JBI version includes a non-return device that prevents battery discharge through the solar module overnight and favours the load balance between the strings.
