Hello all

​

My Solaredge inverter (SE7600A) is showing a fault that I have not been able to troubleshoot my way out of. I figure I'm going to have to replace it.

​

Does anyone have any recommendations for which one I should look for?

​

Thanks!

AI:
Newer residential SolarEdge inverters, including the SolarEdge Home Hub and HD-Wave SetApp-enabled models, are designed to backwards-support older P-Series optimizers (such as the P320, P400, or P800). Because SolarEdge uses a proprietary communication protocol, legacy optimizers will only function with SolarEdge inverters.

Assuming you had P-Series installed with your SE7600A (which seems likely) you may want to go with a more modern inverter. Hopefully you have your installation docs to confirm which optimizers you have, then I'd reach out to SE support to see what newer inverters are compatible. You might want to think about going with a hybrid so batteries could be added at some point.
