Event number Message, cause and corrective measures
10286
Wi-Fi connection lost
The inverter has lost Wi-Fi connection to the selected network.
Corrective measures:
• Ensure that the Wi-Fi router or Wi-Fi access point is still active.
• Ensure that the Wi-Fi router or Wi-Fi access point is in range and is
signalizing correct operation.
• If this message is displayed often, improve the Wi-Fi connection by using
a Wi-Fi repeater.
