Derating / power limiting
Occurs automatically when:
•
input power > max. recommended PV power
•
cooling is inadequate
•
input current > 32 A
•
grid current > 16 A
•
internal or external power reduction (derating)
•
grid frequency too high (according to country setting)
•
limiting signal received via an external interface
