  • Maximum Total Power is 1000W for two modules
  • Maximum Current is 15A per input
  • Available as 1500V UL
  • UL-certified as NEC 2017 Rapid Shutdown Solution
  • Snap to standard module frame or rack mounting
  • Module-level deactivation with automatic or manual shutdown
  • PV array enters rapid shutdown in event of AC grid loss
  • Powerline communication (PLC) signaling
  • Smaller unit dimensions with reduced weight per unit by 25% 
  • Reduced shipping costs with 33% more units per pallet
  • Recessed mounting allows shipments of pre-assembled PV modules
  • Improved heat dissipation with over-temperature and over-voltage protection
  • Improved IP68 rating for greater outdoor exposure
