Derating / power limiting occurs automatically when:
n input power > max. recommended PV power
n cooling is inadequate
n input current too high
n grid current too high
n internal or external derating
n grid frequency too high (according to country setting)
n limiting signal received via an external interface
n output power is limited (set at the inverter)
