I studied physics, math and software engineering in college. I have extensive experience with HVAC Systems, Solar Energy, and Electrical Systems. I am retired from a career in software development. I now run a small business Heisenberg Electric that specializes in repairing HVAC systems.
I built my own battery backup for my solar system. The initial Enphase system was professionally installed. I added 2 Schneider XW Pros to the system to allow off grid operation in a grid down situation.
