How it works
With time-of-use tariffs, energy prices vary by time of day. IQ Energy Management automatically selects the best source—solar, battery, or grid—and schedules home energy use to maximise savings.
IQ Energy Management
AI Optimisation
IQ Energy Management can help in almost any home, but it delivers the most powerful savings when used with a time-of-use tariff.
Using battery power when prices are high
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 can deprioritise EV charging and reduce consumption of the electric water heater at these times, and save money by drawing stored energy from your IQ Battery.
Selling excess solar and battery power
As soon as the sun rises, your Enphase solar system begins generating clean energy. Even under flat electricity tariffs, AI Optimisation in IQ Energy Management delivers smart savings by prioritising solar to power your home and charge your IQ Battery. Any excess energy is exported to the grid, earning feed-in tariff credits. The system also intelligently schedules high-usage appliances—like your EV charger and electric hot water system—to run when solar is abundant or grid tariffs are low. This reduces reliance on grid power and helps lower your energy bills.
Managing energy use with time-of-use tariffs can be complex. IQ Energy Management intelligently forecasts and optimises how you source, use, and store power—helping you stay ahead of changing costs and maximise savings every day, year after year.
