SolexBrick S1?

The SolexBrick S1 is the world’s first ultra-compact device that combines a solar optimizer and MPPT charge controller in one. Its Quad-Channel design processes power more efficiently by handling four inputs in parallel, enabling the circuitry to be condensed into a rugged metal housing small enough to mount directly behind a solar panel. Paired with our InstantMax AI algorithm, each S1 independently maximizes output from its own panel while coordinating seamlessly with other S1 units for smarter overall performance.

This dual innovation delivers three game-changing capabilities: Mix & Match Panels (effortlessly combine different panel types and sizes), Anti-Shadow Optimization (shade one panel, others stay at full power), and Plug-and-Play Expansion (add panels anytime without replacing controllers or rewiring). It’s solar power made simpler, smarter, and ready to grow with you.

Mix & Match Different Panels

In most solar setups, mixing panels of different brands, wattages, or types can cause serious issues—reduced efficiency, system shutdowns, or even zero output. The SolexBrick S1 removes these risks. With each panel equipped with its own S1, every panel works at its maximum potential. That means you can combine any panels you have—old or new, rigid or flexible—and still enjoy a fully optimized connection to your battery without extra controllers.

Anti-Shadow Optimization

Because S1 independently optimizes each panel, it breaks through the limitations of traditional controllers and can maintain 100% normal power generation of other panels even when the sun's angle changes/shadows from obstruction on a single panel, greatly improving the power generation efficiency of the system throughout the day.

390+W are you kidding me?! It’s a partly cloudy day and my panels are dusty... My dog has walked over them, they have paw prints, and it’s still delivering that kind of output. Simply incredible!

Hey the event and the solar panel were a success! The weather proved less than ideal .... The panel was still able to keep up with power demands for over 24 hours...

I was getting around 340w mid afternoon. I can already see this will be replacing other 400w panels for my RV, as the weight and size make it a superior choice despite the fact that it doesn’t have a stand. It’s also less susceptible to damage from wind. So far everything feels premium, and it seems like this team put some strong products out. This will be a permanent addition to my RV setup.

They are equal weight when split, and incredibly light. Fantastic weight for 200 watts. Comparing the watts, they were very close. Panel 1 = 186 W and Panel 2 = 192 W. Max on day 1 was 352 Watts in the Ecoflow very impressive... Not difficult at all, Very convenience.

This new solar panel that is amazing it has built-in power cords. With the S1 charge controller which has AI intelligence. I laid it out on my roof of my Toyota FJ Cruiser to get some extra power for my devices and it is so easy to deploy and fold up.

The SolarBag in the small little carrying case is tiny. I've used 100 Watt solar suitcase bags that are twice the size and way heavier, so we're talking about a small package that is super powerful here.
