3.3.7. Start-up
PV overvoltage protection
Inverters in the TripleLynx CN range include a feature which actively protects the inverter and
PV modules against overvoltage. The function is independent of grid connection and remains
active as long as the inverter is fully functional.
During normal operation the MPP voltage will be in the 250 – 800 V range and the PV overvolt-
age protection remains inactive. If the inverter is disconnected from grid the PV voltage will be
in an open circuit scenario. With high irradiation and low module temperature the voltage may
rise and exceed 860 V. At this point the protection function becomes active.
Upon activation the function will within 1.5 ms, and in a controlled way, take the PV voltage
from being in open circuit to near short circuit. This is done by actively using the transistors in
the inverter's power module. With the PV overvoltage protection activated the input voltage will
be approximately 5 V, leaving just enough power to supply the internal circuits.
When normal grid condition is re-established the inverter will exit the PV overvoltage protection
in a controlled manner taking the MPP voltage from the almost short-circuit level up to the MPP
point in the 250-800 V range.
