Very few mainstream smart thermostats natively "plug and play" directly with proprietary solar inverter apps (like SolarEdge, Enphase Enlighten, or Fronius) out of the box. Solar apps track generation, while thermostat apps track temperature—and brands rarely build direct bilateral cloud integrations for this specific use case.
Instead, the most reliable way to cool your house when solar production is high is to use an open smart thermostat paired with an automation platform or an energy-management ecosystem that pulls data from both devices.
Top options and approaches to achieve this integration include:
To help narrow down the ideal setup, could you tell me:
Yes, this is possible, but the best setup depends heavily on your **solar inverter brand/app**.

Yes, this is possible, but the best setup depends heavily on your solar inverter brand/app. Most smart thermostats do not directly connect to inverter apps like Enphase Enlighten, SolarEdge, Tesla, or Fronius by themselves; usually you add an energy-management “bridge” that watches solar production and tells the thermostat to pre-cool.
Good options:
ecobee Smart Thermostat Premium + Home Assistant (most flexible)
Best if you want: “When solar export exceeds X watts, lower AC setpoint by 2–3°F.”
Home Assistant can read many inverter systems and control ecobee through integrations.
Google Nest Learning Thermostat + an energy monitor/automation platform
Works well if you already use Google Home.
Some energy-monitoring platforms can integrate Nest and automate based on solar production or energy goals.
Emporia Energy Vue energy monitor + compatible thermostat
A practical retrofit if your inverter app does not expose usable data.
Emporia supports thermostat integrations including Nest, Honeywell/Resideo, and Sensi platforms, with energy-management automations.
Inverter-specific smart energy ecosystems
Some solar ecosystems have their own load-control features. For example, SolarEdge has a Home ecosystem designed around managing energy devices alongside its inverters.
A typical automation would look like:

Yes — but the best thermostat depends heavily on your solar inverter brand. You want more than a thermostat that merely has an energy-saving mode; ideally it should receive real-time solar production/excess-power information and pre-cool the house when you're exporting solar.
ecobee Smart Thermostat Premium - $259.99 (Best Buy)
Google Nest Learning Thermostat (4th Gen) - $239.99 (The Home Depot)
ecobee Smart Thermostat Enhanced - $169.99 (ecobee)
Enphase inverter: The most interesting option right now is Enphase IQ Air. Enphase opened preorders in July 2026, with shipments beginning in August. It is specifically designed for the Enphase Energy System and displays live solar production, battery status, and home power use.
SolarEdge inverter: I'd look at the ecobee Smart Thermostat Premium or another compatible HVAC controller, but the key is connecting it through SolarEdge's energy-management ecosystem rather than relying on the thermostat alone. SolarEdge ONE supports prioritizing compatible devices for excess-PV consumption, and its ONE Controller can integrate selected third-party equipment.
Generac/PWRcell 2: ecobee Premium or Enhanced has an unusually deep integration with PWRcell 2, including solar production, consumption and battery information.
Other inverter brands: A thermostat such as ecobee or Nest can often be automated using the inverter's API, smart-home platform, Home Assistant, or an energy monitor—but that's a different level of integration and may require additional hardware.
If your goal is specifically:
"When my panels are producing, say, 4 kW and the house only needs 2 kW, use some of that surplus to pre-cool the house." I'd prioritize direct inverter/energy-system integration over choosing a thermostat based purely on its HVAC features.
Tell me the brand and model of your solar inverter (e.g. Enphase IQ8, SolarEdge HD Wave, Tesla, Growatt, etc.), and whether you have a battery. I can then identify the thermostat/setup that can actually do the excess-solar pre-cooling automatically, rather than just recommending generic smart thermostats.
Direct native "out-of-the-box" integration between standalone smart thermostats (like Nest or Ecobee) and third-party solar inverter apps (like SolarEdge, Enphase, or GoodWe) is still relatively rare, but you have a few great ways to make this happen depending on your hardware and comfort with smart home platforms. 1.…
Direct native "out-of-the-box" integration between standalone smart thermostats (like Nest or Ecobee) and third-party solar inverter apps (like SolarEdge, Enphase, or GoodWe) is still relatively rare, but you have a few great ways to make this happen depending on your hardware and comfort with smart home platforms.
If you already have a standard thermostat (Ecobee, Nest, Honeywell) and a major solar inverter (SolarEdge, Enphase, Sungrow), the most reliable way to pre-cool your house during peak production is via a smart home hub like Home Assistant, SmartThings , or Hubitat.
To help narrow down the best setup for your home, tell me:
Yes — what you want is **solar-aware pre-cooling**: when PV output is high, the system lowers the thermostat setpoint so your AC uses more of your own solar instead of exporting it.

Yes — what you want is solar-aware pre-cooling: when PV output is high, the system lowers the thermostat setpoint so your AC uses more of your own solar instead of exporting it.
The important catch is that the thermostat usually doesn't talk directly to the inverter app. The cleanest setups use an energy-management layer between them.
The ecobee Smart Thermostat Premium is a strong choice because it has broad smart-home/automation compatibility. You can have an automation such as:
If solar production/excess power > 2.5 kW for 5 minutes → lower AC setpoint by 2–3°F. Then restore the normal temperature when production falls.
If you're willing to use an energy-monitoring platform, Emporia is particularly well suited to exactly this use case. Its app supports Nest, Honeywell/Resideo, and Sensi thermostats and has an Excess Solar Optimization feature that adjusts connected thermostats when there is excess generation.
That means you could use:
This avoids having to build your own Home Assistant automation.
Home Assistant is the better solution. It can ingest solar-production data from supported inverter/monitoring systems and trigger thermostat actions based on production. For example, Home Assistant can use PV generation as an automation trigger and control household loads accordingly.
This is especially attractive if your inverter has a good local/API integration. For example, SolarEdge currently provides an API with production and consumption data.
Before I recommend the exact thermostat/setup, tell me the brand and model of your solar inverter (e.g. SolarEdge, Enphase, Tesla, SMA, Fronius, Growatt) and whether your AC is central HVAC or mini-split. That will determine whether you can do this directly, through Emporia, or through Home Assistant.
This avoids having to build your own Home Assistant automation.
Directly linking a standalone solar inverter app (like SolarEdge, Enphase, or Emporia) natively to a brand-name smart thermostat (like **ecobee** or **Nest** ) for direct solar-surplus cooling is rare, but **smart energy management platforms like Emporia Energy or home automation hubs like Home Assistant** can bridge…
Directly linking a standalone solar inverter app (like SolarEdge, Enphase, or Emporia) natively to a brand-name smart thermostat (like ecobee or Nest ) for direct solar-surplus cooling is rare, but smart energy management platforms like Emporia Energy or home automation hubs like Home Assistant can bridge the gap.
Most proprietary solar inverter apps do not feature direct, out-of-the-box native triggers to drop your indoor AC temperature. Instead, setup requires an energy monitoring ecosystem or a middleman automation platform.
How to Achieve Solar-Driven Cooling
| Approach / Tool | How It Works | Key Benefit |
|---|---|---|
| Emporia Vue + Compatible Thermostat Go to product viewer dialog for this item. | An Emporia energy monitor tracks net grid/solar flow, using its "Excess Solar Optimization" feature to pre-cool the home. | Direct energy-monitoring hardware tracking your actual production vs. export. |
| Home Assistant (Open Source) | Connects via local APIs to your specific solar inverter (Enphase, SolarEdge, etc.) and your smart thermostat (ecobee, Nest, Honeywell). | Complete customization; triggers an automation script the second net export exceeds a certain wattage. |
| Smart Plugs / Minor Loads First | Most inverter apps (SolarEdge/Enphase) natively control smart relays or plugs for high-draw appliances rather than thermostats. | Easiest native integration for water heaters or pool pumps. |

However, you can seamlessly achieve this "pre-cooling when production is high" setup using smart energy platforms or a smart home hub as the bridge. [1][2]

is a good thermostat, but I wouldn't choose it specifically for this solar-surplus use case without knowing your inverter. Its normal smart scheduling isn't the same thing as responding to instantaneous PV surplus.
If your goal is something like:
"When I'm exporting >2 kW of solar for 10 minutes, lower the AC setpoint from 75°F to 72°F; when solar drops, return to 75°F." That's very doable, but the exact implementation depends on your inverter. It can be done through the inverter's native energy-management system, or sometimes through a home-automation platform that reads the inverter's production/export data and controls the thermostat.
Tell me the make/model of your solar inverter (e.g. SolarEdge, Enphase, Tesla, Fronius, SMA, etc.) and your thermostat/HVAC type, and I can tell you exactly which thermostat or setup will accomplish this, including whether you need an additional energy meter/controller.

A few good paths:
** or **
** can be good thermostat hardware, but you'll generally need a bridge such as Home Assistant, the inverter's API, or a smart-energy controller to actually implement "solar surplus → pre-cool."
The control logic I'd aim for is something like:
If solar production is > household consumption by 2–3 kW for 10 minutes, lower the AC setpoint by 2–3°F. Stop pre-cooling when surplus falls below 500 W, then return to the normal setpoint. That can substantially increase self-consumption without making the house uncomfortably cold.
Tell me the make/model of your solar inverter (e.g. SolarEdge, Enphase, Tesla, Fronius, Solis, etc.) and whether you have a battery. I can then identify the thermostat/control setup that will actually integrate with its app and give you the simplest way to automate the pre-cooling.

Directly linking a standalone smart thermostat (like an Ecobee, Nest , or Honeywell ) to a solar inverter app (like SolarEdge, Enphase Enlighten , or SMA Sunny Portal ) out-of-the-box is surprisingly rare. Most major inverter apps and thermostat ecosystems operate in closed or separate clouds without a direct "plug-and-play" button to sync HVAC cooling to live solar production.
Instead, achieving this "pre-cool the house when the sun is peaking" behavior relies on one of three reliable approaches.
How to Achieve Solar-Triggered Cooling
Rather than relying on the inverter app and thermostat to talk to each other directly, use a middleman platform like Home Assistant, Hubitat , or Apple HomeKit.
If your inverter app doesn't expose real-time production data easily to a smart home hub, a dedicated whole-home energy monitor can bridge the gap.
Some branded solar ecosystems have proprietary load-control hardware designed to talk to smart appliances or heat pumps.
