EG4 Hybrid Solar Window Unit — 12,000 BTU Solar AC
Beat the heat on sunshine. The EG4 Hybrid Solar Window Unit is a 12,000 BTU window air conditioner that runs on solar, grid power, or both — cooling a room up to 600 sq ft while it quietly shrinks your summer electric bill. No inverter, no battery bank, no professional install.
Why You'll Love The EG4 Hybrid Solar Window Unit
-
Cool a room straight from the sun. Wire up about 1,200W of solar panels with the built-in MC4 connectors, and it runs mostly on free solar by day, blending in grid power only when it needs to.
-
Three ways to run it. Choose Solar Only, Solar + Grid, or Grid Only, so you stay cool whether it's blazing sun, cloudy, or after dark.
-
Quiet, efficient, and smart. A variable-speed inverter compressor dials cooling from 2,500 to 12,000 BTU and runs as quiet as 52 dB — all controllable from the app, the remote, or the unit itself.
-
Solar cooling made simple. It drops into a standard double-hung window with the included hardware and plugs into a regular 115V outlet, so you can dip into solar without upgrading your whole home.
Your life, with the EG4 Hybrid Solar Window Unit
Every summer it's the same story: crank the AC, then wince when the electric bill lands. And going solar always felt like a huge, expensive commitment — panels, inverters, batteries, an electrician for a week.
The EG4 Hybrid Solar Window Unit is the easy way in. It's a window air conditioner that happens to run on the sun. Connect about 1,200 watts of panels, slide it into your window, and plug it into a normal outlet — that's it. On sunny afternoons it cools your room mostly on free solar; when clouds roll in or the sun sets, it quietly leans on the grid so you never feel a change.
You're in control the whole time. The app shows you real-time solar and grid input, and lets you switch modes, set schedules, and adjust the temperature from your phone. Prefer buttons? Use the remote or the onboard controls.
And it's built to be lived with. The variable-speed compressor ramps smoothly from 2,500 to 12,000 BTU instead of blasting on and off, so the room stays comfortable and the unit stays quiet — as low as 52 decibels. A washable filter with cleaning reminders keeps it running its best.
Whether it's a bedroom, a home office, a garage, or a workshop, this is the simplest way to cool a space on sunshine — and watch your summer bill finally come down.
