Bought my house with a solar/ single PW2 setup that was just upgraded to a new single PW3 due to the recall. I needed more backup so at the advice of our installer I added a second solar/PW system with 3 PWs. The systems are separate to preserve the original system’s export rate under SCEs old plan.

I’m trying to understand how the systems interact with one another. I constantly see activity like the attached images when I check the system status throughout the day. It’s frustrating to see that we are apparently drawing from the grid while the secondary system is exporting. I’m guessing something is not configured correctly?

I appreciate any insight or advice, thank you.
