Constantly low contact resistance of the PV connectors is key for efficient operation and safe energy feed-in. Increasing contact resistance, e. g. due to deficient material characteristics, can weaken the efficiency of the entire PV system.

eBOS stands for electrical Balance Of Systems. All electrical components of the DC side of the system except the inverter and module form the eBOS application. As the lifelines of a PV system, the eBOS system ensures that the power generated by the modules is gathered and transferred efficiently, reliably and safely.
