Photovoltaic (PV) String Monitoring Cards for Combiner Box Applications
The Photovoltaic (PV) String Monitoring Cards for Combiner Box Applications is part of the Mersen (formerly Ferraz Shawmut) special purpose fuses line, distributed by Gross Automation.
In order to guarantee long term power performance in mid- and large-scale photovoltaic (PV) installations, it is mandatory to properly monitor the production of the installation over time, at the string level. String level monitoring is guaranteed to maximize energy production, optimize facility management, and decrease operations and maintenance costs. Mersen, a worldwide leader in electrical protection solutions, has created a complete and dedicated product offering for photovoltaic applications, the HelioProtection® program. The latest innovation into this program is a line of string monitoring products that can be customized to the target installation.
