Hi,
I have 2 Netmetals with the same damage. It burns alway Q1 as you can see on the foto.
What is Q1? I think its the DC converter.
Thanks Chris
Lightning strike has blown out your OVP (over voltage protection) transistor.
Very likely that a simple part change will not help, damage looks big.
Can you post close up photo near the DC input jack? Need to see if components in that area are also damaged or not.
Usually you can prevent it by correctly grounding your installation.
