DC solutions

Wire harness with Stäubli DC components

eBOS stands for Electrical Balance of the Systems. This comprises all the DC wiring components of the PV system between and except the modules and the inverter. 

The eBOS solution ensures that the power generated by the modules is gathered and transferred efficiently, reliably and safely. To ensure that the DC wiring system meets the life expectancy of the PV plant, an impeccable product is merely one aspect of the solution.

Modular plug-and-play wiring system

A modular cabling concept allows for the highest flexibility in designing your DC wiring according to your configuration needs

The modularity of the Stäubli eBOS offerings facilitates modifications during the entire PV system lifecycle in case of extensions or changes to the PV plant.

Cable harness

Plug-and-play cable jumper and homerun cable

  • to connect modules or strings with MC4 or MC4-Evo 2 connectors

Branch connector

Compact and space-saving
 

  • to combine two strings to one
     

In-line fuse

Ready-to-use product, protects PV strings from overcurrent

  • minimal energy loss
  • robust housing

Why does it matter?

72% of all issues relate to field-made connectors and wire management in DC Distribution

 

Connectors and wire management top the list.

  • The SolarGrade Report published the top 20 most common issue types by volume and severity in PV systems.

  • PV systems contain more wires and connectors than any other piece of equipment, so these categories are expected to have higher quantities of issues.

How you benefit from our modular wire harness solution?

Expert knowledge

  • Since 1996, Stäubli’s Original MC4 connectors have powered more than 50% of the global PV capacity worldwide, proving their reliability and industry trust.
  • Our expertise and experience in DC wiring are fully applied to customers' installations through dedicated customer service and support 

Proven reliabilty

  • Certified product safety meets the relevant industry standards, proven by TÜV Rheinland and/or UL certificates, granting safe and reliable performance.
  • Best-in-class manufacturing expertise for advanced material processing and the highest insulation performance, granting long product lifetimes and compliance in harsh environments.

Time and cost saving

  • Optimized design concepts and reduced number of components used, which means less material and lower initial costs (optimized CAPEX).
  • Simplified system diagnosis process to save time and reduce O&M efforts.

Highest quality to guarantee long-term reliability

  • Ready-to-use product design and customized cable harnesses can speed up installation time, improve installation quality and reduce potential risks of failure to lower TCO (Total Cost of Ownership).
  • Replacement parts are available for rapid ordering, thus reducing downtime.
