The Enphase IQ System Controller 3 INT: Smart Energy Control for Any Setup
When it comes to solar, it's all about being efficient, reliable, and easy to use. Want to give your customers something more than just solar panels? There's a new solution that makes a real difference: the Enphase IQ System Controller 3 INT. This powerful brain for your energy system gives you smooth energy control and a solid backup option. Best of all, it works for homes and businesses.

What is the Enphase IQ System Controller 3 INT?
Basically, it's the heart of a smart energy management system. The IQ System Controller manages how solar power, the grid, and batteries work together. It automatically switches between grid power and stored energy, so your customers have power no matter what – even if there's a blackout.
Whether it's for using your own solar power, having partial backup, or going completely off-grid, this controller makes sure everything switches smoothly. It works perfectly with Enphase IQ microinverters and IQ Batteries, bringing everything together in one smart package.
Why is the Enphase IQ System Controller the Best Choice for Your Next Project?
We could go on and on, but here are the main reasons:
Automatic Backup Switching: The built-in Automatic Transfer Switch (ATS) seamlessly switches to backup power when the grid goes down. No need to do anything, just reliable power.
Easy to Install Anywhere: It works indoors or outdoors, thanks to its tough IP55 casing. Great for all sorts of setups, from small homes to big businesses.
Works Perfectly Together: It's designed to work with Enphase's IQ8 microinverters, so you can easily build a complete energy system.
Smart Monitoring: With the Enphase App, your customers can see exactly how much energy they're making, storing, and using, so they can manage their power the best way possible.
What's in it for Your Customers? And for You?
Simply put, the Enphase IQ Controller 3 INT gives your customers peace of mind and makes your job easier and more reliable. Here's what you get:
More Energy Independence: Smart energy control lets your customers use their own solar power to the fullest, and blackouts won't bother them anymore.
