Derating / power limiting occurs automatically when:
n input power > max. recommended PV power
n Cooling is inadequate
n Input current too high
n Output current too high
n Grid frequency too high (in accordance with country
setting)
n Limiting signal on external interface
n Output power limited (set on the inverter)
