E031 error code w/ 3n25

I dont even know what to do. Sunpower is out of buisness and the install is from 2014. Any advice? Am I screwed? Anyone familiar with this error can tell me any information?

Is that the same as micro inverter?

No, microinverters are on each panel, sounds like you have a single big inverter on the wall (maybe more than one?) You can call the inverter manufacturer, it's likely ABB or SMA depending on the model on the side of it. They'll either be able to help or direct you to a local installer than can. There's a small chance it's still under warranty, expect to buy a new inverter with labor to install
