The SOLARLOK Interconnection System delivers a flexible solution for easy and reliable interconnections from photovoltaic modules to the DC/AC converter. The entire system concept is based on cost-effective and reliable processing of individual interconnection system components. This significantly reduces installation costs of the solar energy system.

The junction box concept is based on a flexible, open system structure, which allows serial as well as parallel interconnection via direct wire connect or separable connectors. Within the junction box, up to six termination rails are available for photovoltaic foil connection. The male and female cable connector was designed for high voltage and high current-carrying capacity, in addition to the well established IP 67 sealing requirement in the photovoltaic industry.

Mating safety for the SOLARLOK Interconnection System is provided by polarized keyed housings, fully shrouded contacts, high cycle life, and the squeeze-to-release connection system. In addition, a wide operating temperature range and multi-national approval for photovoltaic connection systems complement the robust product specification.

The design of the male and female receptacle for the junction box and the DC/AC converter follow the cable connector "click philosophy" for quick and secure mating even in difficult mounting positions. As an added benefit, the junction box can be provided pre-configured with diodes, jumpers, plug connectors, and solar cable pigtails as needed.
