Help translating to electrician.
Hello all, hope you're all doing well. I'm currently in the middle of a solar DIY project and I'm in the home stretch. I'm currently getting quotes from electricians and they're all telling me something different. I was hoping someone could help me determine what I need electrically, without worrying about codes and ordinances, to meet my goals.
Goal: my goal is to reduce my power bill. I'm not trying to go off grid at all. If my panels produce Example#kW's per hour, I want to reduce my power usage by that much per hour, and pull the excess need from the grid. I'm hoping that's possible.
My Setup: Currently I have two panel arrays on my roof. 4 x 500kW and 9 x 500kW. They run into a junction box and the four wires run in conduit down to my main electrical panel in my garage. Next to my panel I have 2 x EG4 6000xp inverters and 3 x EG4 Lifepower4 batteries (The idea being that the batteries could store any excess and provide power until they run out at night).
I'm also asking them to upgrade my panel from 150A x 20 breakers to 150A x 30/40 breakers at the same time. My old panel could be used as a junction box if that's necessary. Can you help me understand exactly what I need to meet my goal without having to choose specific circuits, etc? I appreciate the help.
