If you have a dynamic rate plan, the price of energy varies quarter hourly based on the availability of renewable energy and the amount of demand across the grid. IQ Energy Management constantly adjusts the source of energy—solar, battery, or grid—and automatically schedules how and when energy is consumed in your home to maximise savings.
On winter nights, there can be an abundance of wind-generated electricity on the grid. While most people sleep, high supply combined with low demand keeps the electricity price low. The prices can even turn negative. In this scenario, IQ Energy Management responds by charging your EV and your battery with inexpensive grid power.
Before sunrise, when there’s no sun and little wind, renewable energy production is low. But demand is high as people wake up and get ready for the day, so electricity prices rise. IQ Energy Management will be able to deprioritise EV charging at these times and save you money by drawing stored energy from your IQ Battery.
Your system starts producing solar energy once the sun rises, but daytime demand keeps electricity prices high. In AI Optimisation mode, IQ Energy Management powers your home with solar and sends any excess power from the panels to the IQ Battery, while choosing not to run your EV charger with expensive grid power.
During the summer, there’s usually ample solar available in the afternoons. Paired with low demand, this high supply can even create negative energy prices—meaning you get paid to use power from the grid. To take advantage, IQ Energy Management prevents solar exports while maximising grid consumption by running your EV charger and charging the IQ Battery.
