Inside the home
For years, Enphase lived on the roof and in the garage. Enphase Air lives where the homeowner looks—and that changes everything.
Visibility
Seen every single day
Microinverters sit on the roof. Batteries sit in the garage. Enphase Air lives where the homeowner looks.
Engagement
Installed on day one
So the savings start, and the energy view comes alive, long before the panels do.
Upgrades
A natural next step
The ideal add-on for any Enphase system—and a natural lead-in to batteries, EV charging, and more.
accessibility
No app required
Some homeowners never open the app. Now the whole energy story lives on the wall.
Cool savings
Comfort that pays for itself
Enphase Air fine-tunes every degree using live data—solar, battery, rates, weather, even EV charging—to save you money.
Basic savings
Up to $55/year
In hot, sunny climates, Enphase Air pre-cools your home midday using surplus solar and lower-cost grid power, so your HVAC runs less when rates peak later in the day.
Combined savings
Up to $130/year
With a demand response program from your local utility, Enphase Air briefly adjusts your temperature when grid demand peaks, earning credits on top of everyday savings.
Ultimate savings
Up to $275/year
With an IQ Battery on NEM 3.0 in California, Enphase Air prioritizes storing low-cost daytime energy, making it available to help power your home when evening electricity rates peak.
Estimated average annual savings for homes with electric heating and cooling. Actual savings vary by climate, system configuration, equipment, utility rate plan, and local program availability, and are not guaranteed.

One Enphase Air for the primary zone. Multiple zones or HVAC systems? Just add Enphase Air for secondary zones. Same beautiful hardware, everywhere.

you're done

The Enphase App makes it simple—about 10 minutes per zone. Watch the Enphase Air installation video for step-by-step directions.
Pure genius
Aware, so you don't have to be
The Enphase AI engine is aware of your home’s solar production and energy use, and turns what it learns into comfort and savings, automatically.
Solar-aware
Pre-cools using excess solar power to save energy after sunset, so nothing goes to waste.
Weather-aware
Pre-cools before a hot afternoon, pre-heats before a cold morning, timed to the forecast.
Battery-aware
Cools or heats in advance when batteries are full, so they can export when rates spike.
Rate-aware
Reads your utility rate plan and shifts cooling and heating to the cheapest windows of the day.
EV-aware
Factors in your EV charging schedule so your car and your comfort never compete for power.
Grid-aware
Participates in utility demand response—earning credits, automatically, without you noticing.
