Yaskawa – Solectria Solar, just introduced its Commercial Rapid Shutdown Combiner for three-phase string inverters. This Commercial Rapid Shutdown Combiner offers a complete solution to NEC 2014 & 2017, Article 690.12, requiring commercial rooftop PV installations to de-energize DC conductors outside the PV array boundary.
The Commercial Rapid Shutdown Combiner’s design integrates seamlessly with Yaskawa – Solectria Solar’s PVI 14-60 TL three-phase, transformerless inverters. It allows operation of 1 or 2 MPPT zone configurations with up to 5 strings per MPPT zone.
If the Rapid Shutdown Combiner is enabled, the array automatically shuts down the system upon loss of AC power to the site, without an additional power supply, disconnect or activation switch. Together, Yaskawa – Solectria Solar’s PVI 14-60TL three-phase, transformerless inverters and Commercial Rapid Shutdown Combiner provide a fully-integrated solution and the simplest way to achieve compliance with NEC 2014 & 2017, Article 690.12.
