Event number Message, cause and corrective measures
10353 Webconnect error: registration of the SIP registry has not responded
SIP Registrar not fully available.
Corrective measures:
• Ensure that the network cable at the inverter is correctly connected.
• Check the configuration of the router.
10502
Active power limited AC frequency
The inverter has reduced its power due to a too-high power frequency to en-
sure grid stability.
Corrective measures:
• If possible, check the power frequency and observe how often
fluctuations occur. If fluctuations occur frequently and this message is
displayed often, contact the grid operator and request approval to
change the operating parameters of the inverter. If the grid operator
gives his approval, discuss any changes to the operating parameters
with Service (see Section 15 "Contact", page 96).
