Components and solutions for photovoltaic parks

Reliable and tailor-made to suit your individual requirements

 
 

Efficient system operation at all levels

We develop and produce the appropriate combiner boxes for all levels of your photovoltaic system. All functional areas, from transmission and fuse protection to monitoring, are matched according to the specific application and covered with our quality products.

 

Level 1

  • Service bundling of separate strings and connection with inverter or level-2 combiner boxes
  • Optional integration of protection and monitoring functions

Level 2

  • Bundling of cables emerging from level 1 to an outgoing cable for connection to the inverter
  • Optional integration of protection and monitoring functions

Communication

  • Link between the individual components within the network
  • Query and bundling of all compiled information (including that from additional devices such as cameral systems or weather stations)
 

High-quality components, intelligently bundled

We bundle high-quality components to provide innovative solutions which can be individually adapted to your needs. This begins at the system planning stage, because at Weidmüller you get all connection components from a single source.

Monitoring

Monitoring


    Integrated power monitoring provided by the Transclinic monitoring system enables errors to be diagnosed accurately. This means you can optimise specific parts of your system and reduce maintenance costs considerably.

    Transclinic complies with all the latest standards and comes with two digital inputs for monitoring switch settings and surge protection. Special feature: depending on the version, up to two strings can be monitored via a single channel.

Independent power supply

Independent power supply


    The unique, self-supplying power supply unit Transclinic BKE enables power to be supplied directly from the DC voltage of the PV system. Additional wiring for a local AC supply is not required. This simplifies installation and maintenance of the entire system.

String fuses

String fuses


    With fuses on the positive and negative side of each string, we guarantee the highest security for your system and peripherals.

Lightning and surge protection

Lightning and surge protection


    Surge protection systems from Weidmüller have proven themselves in many different industries and are therefore a standard feature in our combiner boxes.

    Optimum protection for each specific application is carefully selected by our application engineers and incorporated in the design.

    The products used comply with current standards and have been developed specifically for, amongst other things, the DC side of photovoltaic systems.
