The SOLR ENERGY team was selected to diagnose and repair an 124.8 KW PV System located on a Marine Corps Center in Huntsville, AL. The system did not meet the Rapid shut down provisions of the Nation Electrical Code. SOLR ENERGY designed and implemented a DC Rapid shutdown system to bring this system up to code and make it safe to maintain.
This system utilizes qty (520) Sharp 240 watt (60) cell solar modules, installed on 4 separate buildings with Fronius inverters and a 60 KW Solectria central inverter, the solar arrays were installed using a Refusol ballasted racking system. The system was engineered to reduce the utility cost for the USMC for this location by approximately $16,550 per year. Huntsville’s USMC Military Training center now has one of the first code compliant PV systems in the country.
The SOLR Energy team was selected to design and install an Arc Fault Detection and Interruption (AFDI) system with a Rapid Shutdown (RS) to meet Articles 690.11 & 690.12 of the National Electrical code for safety. Now the system can be safely disabled with the push of a button for regular maintenance, making solar better!
