Northern Electric Power Technology Inc. (NEP)’s PVG-4 is an easily installed standalone rapid shutdown product, proving NEC-2017 and NEC-2020 compliance at lower cost and with some added safety features. Cool things to note:
- You can connect four PV modules to one device to achieve that lowest cost (with three to one and 2 to 1 options on the way).
- PV level thermal shutdown enables an extra failsafe layer of system-shutdown protection for first responders.
- Configured DC cables and connectors will match the PV connector brand and lower your AHJ rejection risks.
- The PVG-4 is set up for two-way communication instead of the standard one-way. This allows for PV data monitoring and data feedback that confirms if the RSD functioned correctly.
- NEP has a service mode you can switch to in order to perform IV curve tracing. This removes several O&M headaches compared to similar products that will need to be unplugged to perform the same tasks.
