First off thank you for making it sensible to me. Other posts advised to make sure converter was off so I flipped the main breaker.
Based on what you told me I followed the procedure and good news bad news. Leaving the main on and flipping general purpose breaker it worked when I turned on inverter but only on 1 outlet out of 6. At least its the kitchen outlet which would be used the most. There is another open outlet on the inverter I guess I can plug computer, chargers, and periodically the tv as needed. Why the installation only fed one outlet seems like a bit of a waste unless I'm doing something wrong. Thanks once again and still open to any advice.
If you are adept at solar install I have a question on adding another panel.
