Does sun2000 inverter derate when altitude 4000 m?

The power of SUN2000 inverter doesn't derate when altitude ≤ 4000m. When altitude > 4000 m, DC voltage derating of SUN2000 inverter should be taken into consideration and DC voltage derates in accordance with 19.5V/100m. The rated AC voltage (800V) of the SUN2000 inverter doesn't derate when altitude ≤ 5000 m.

Why is my sun2000 inverter NOT working?

Abnormal external conditions trigger the protection for the inverter circuit inside the SUN2000. The possible causes are as follows: Reason ID = 13A sharp drop in grid voltage or a short-circuit has occurred, resulting in a fault in the voltage check circuit of the SUN2000.
