The Physics of Home Energy Fusion

The primary challenge in home electrification is balancing the loads. The Solar + Battery + EV Fusion Simulator helps you size each component correctly. If your daily solar production exceeds your home and car needs, the excess is stored in the battery or exported to the grid. If production falls short, the battery discharges first, minimizing expensive grid usage.

Using the system to charge your EV is often the best use of excess solar, as it converts otherwise low-value export power into high-value, free "fuel" for your car.
