PV options added to standard connector range

The connector offering available from Stäubli Electrical Connectors now includes the MC4 solar power range. The high performance PV units were branded as Multi-Contact before the company's change of name earlier this year. More than one billion photovoltaic connectors in the MC4 family have been installed worldwide over the past 20 years, often operating in the harshest of environments.

The snap-fit MC4 units are suitable for cable cross-sections from 1.5mm² to 10mm² and are rated for currents up to 45A. Resistance to UV, ammonia and salt spray enables the IP68 rated devices to operate in harsh environments.

Although only small, they can have a large impact on the bankability of PV plants. Their use of MULTILAM technology, a proprietary contact system that uses spring contact elements to produce multiple contact points, ensures low service cost, low power losses and reduced down-times.

The latest addition to the MC4 range is the MC4-Evo2, whose high voltage rating of up to 1,500VDC means that solar power operators can benefit from longer cable strings when linking solar fields. It has a high current carrying capacity of up to 69A, helped by a streamlined design that improves heat dissipation.
