Stäubli Electrical Connectors looks to exhibit its MC4 solar power connector system at the Solar & Storage Live exhibition in Birmingham, this September. Enabling the bankability required for today’s PV projects, these connectors have been installed in over 200 GW of PV systems worldwide.

Part of the MC4 connector range on show will be the MC4-EVO 2, which minimises power losses thanks to its high current carrying capacity of up to 69A. A high voltage rating of up to 1500V DC means that longer series strings can be used in PV arrays on large-scale solar projects.

 

Suitable for cable cross-sections between 4 mm2 and 10 mm2 (12 to 8 AWG), the connector has a polyamide casing with improved impact resistance and enhanced sealing. Ammonia and salt spray resistance also enables operation in harsh environments.

 

Also featuring on the Stäubli stand will be the MC4-EVO AC, a three-pole AC connector for use with micro or nano PV inverters. Designed for module and string level applications, its low profile allows it to fit within the panel framework, enabling modules to be stacked without the use of spacers.

 

With a current carrying capacity of up to 32A, it has a rated voltage of 600V AC (UL) and 400V AC (IEC). Accepted cable cross-sections range from 1.5 mm2 to 4 mm2.

 

The company also offers a suite of high performance accessories including junction boxes, cabling and tools.

 

Solar & Storage Live 2019 takes place at the NEC, Birmingham from 17 to 19 September 2019, and Stäubli can be found on Stand E11.
