Photovoltaics

Long-term profitable, effective running systems

Large photovoltaic parks are associated with enormous costs and risks for owners and operators. Their goal is a long-term, focused return-on-investment. Total operating costs are therefore a critical success factor. The requirement for the development and construction of today's photovoltaic systems is to operate them efficiently - economically and without downtimes. In addition, upcoming technological improvements such as decentralization, IoT and data analysis play an important role for future photovoltaic ecosystems.

Our customers benefit from our many years of experience in the photovoltaic industry, our know-how, our comprehensive range of services and our global presence. We prove this with more than 162,000 installed combiner boxes, around 70 million connected panels with 14.2 GW, over 11 years of market experience and our global support in more than 100 countries. We combine finely attuned components to create innovative solutions that are adapted to your individual needs.

Product highlights for Photovoltaics

Combiner box PV Next. Easy. Fast. Safe. Product innovation

PV Next is a new standardised, highly-scalable combiner box for residentials and commercial photovoltaic applications. It's innovative concept covers about 75 % of today's standard requirements for combiner boxes, enabling suppliers to work safer and simpler while significantly reducing their costs.The integrated PUSH IN technology significantly reduces assembly times while minimising the risk of errors and resulting consequences. For the installer, the connection concept for wiring the system results in considerable advantages. PV Next is the first combiner box worldwide based on a standardised printed circuit board design.

Combiner box PV Next. Easy. Fast. Safe.
Benefits for residential and commercial applications:
  • Covers all common inverter concepts
  • Up to 3 inputs/outputs with PUSH IN technology
  • Up to 3 MPPT variants
  • Fused or non-fused variants

Monitoring and SCADA systems

One eye always on performance

Excellent compatibility with leading providers - our solutions for all-round application with monitoring and SCADA systems

Combiner boxes (CBs) with string monitoring from Weidmüller can be integrated seamlessly into any system topology and ensure error-free data entry using modern monitoring and SCADA systems. Our Transclinic monitoring system continuously analyses current and voltage, the status of surge voltage arresters, and load-break switches, as well as the combiner box temperature in your photovoltaic system, enabling highly detailed system monitoring.

Negative influences, which lead to reduced output, can be detected and rectified immediately. The open Modbus RTU RS485 protocol simplifies incorporation in monitoring and SCADA systems and reinforces communication security, making this device series the perfect all-rounder for any monitoring and SCADA system provider.

Weidmüller works with leading monitoring and SCADA systems providers and data loggers, among others including: Meteocontrol, skytron energy, Solare Datensysteme GmbH, GreenPowerMonitor, PV Hardware or Axis

With the help of condition monitoring systems, users can check the correct operation of the plant, or detect and avoid a problem that can lead to a shutdown of the system.
