Rated input current 14 A 16.7 A
Maximum input power 9,250 W 10,800 W
Rated input power 8,400 W 10,000 W
Recommended maximum PV output 10,500 Wp 12,500 Wp
Derating / restriction automatic when:
• input power is higher
• the device is not cooled sufficiently
• input currents > 27 A
automatic when:
• input power is higher
• the device is not cooled sufficiently
• input currents > 32 A
Higher currents are restricted by the inverter and therefore will not damage it.
