Enphase Energy, Inc. (NASDAQ: ENPH) opened pre-orders for IQ Air, a smart thermostat designed to integrate with the Enphase Energy System, on July 8, 2026.

The device displays live solar production, battery activity, and home power use on an HD color touchscreen. It supports multi-zone HVAC setups, with a primary unit serving as the main in-home power display and secondary units available for additional zones.

IQ Air is designed to use AI and software controls to optimize HVAC operation based on solar production, battery state of charge, time-of-use rates, weather forecasts, and virtual power plant events. According to Enphase modeling, the thermostat is designed to help homeowners save up to an additional $275 per year, though the company notes actual savings will depend on system configuration, climate, local programs, HVAC equipment, and utility rate structure.

The thermostat includes proximity sensing, auto-dimming, humidity and ventilation control, Wi-Fi, and a built-in cellular connection to the Enphase Cloud. It is designed to work with most 24-volt HVAC systems and is said to take approximately 10 minutes per zone to install.

"IQ Air brings Enphase intelligence to one of the most familiar control points in the home," said Ravi Pervela, senior vice president of cloud, security, and HEMS at Enphase Energy. "Homeowners can manage comfort, view live power flow at the wall, and use the Enphase App for broader control across solar, batteries, rates, and grid programs."

IQ Air is available for pre-order online and through Enphase distribution partners. Shipments are expected to begin in August 2026.
