EBOS - ELECTRICAL BALANCE OF SYSTEMS – Product portfolio extension

The lifelines of a PV system

Stäubli provides high-quality components for eBOS applications along the entire electrical PV supply chain, based on the many years of expertise in connecting reliably and safely any type of PV system.

Connected for extended efficiency and reliability

The recent portfolio enhancement offers the latest technology innovations and introduces new products such as a TÜV certified In-Line-Fuse harness and a Y-splitter harness as interconnection solutions. By teaming up with the manufacturing partner Jurchen Technology, two experts meet. The Stäubli know-how in developing advanced contact technology and designing quality products pairs with Jurchen Technology’s manufacturing expertise. With this partnership, Stäubli provides its customers with high-quality product solutions based on a unique and proven in-use vulcanization manufacturing process. This sophisticated technique grants an incomparable degree of impermeability.

Connected for lower total cost of ownership (TCO)

Both new products in the Stäubli PV eBOS portfolio have officially been tested by a notified body and hold a TÜV Rheinland certificate. By choosing these product solutions the customer benefits from highest efficiency due to low contact resistance, less leakage currents and perfect isolation given by the innovative product design and manufacturing technology. With very short assembly time, less material use, a smaller DC combiner box, this latest Stäubli all-in-one eBOS solution allows for cost savings compared to conventional DC cabling systems. Based on proven Stäubli quality, the new products accomplish the offering for eBOS application, guaranteeing safer, more reliable, and bankable PV assets at a lower total cost of ownership (TCO).
