3-Step Plug-and-Play InstallationStep 1: Connect SolexBrick S1 to your solar panelStep 2: Link the solar panels in seriesStep 3: Connect SolexBrick to your energy storage batteryThat's it—clean energy, simplified.
Mixing different solar panels can be risky and may affect your entire system. But with our S1 controllers, you can safely combine panels of different brands and specs. Expand your existing setup without replacing a thing—and enjoy more power, more space, and a smarter system.
One shaded panel shouldn’t drag down your whole system. S1 controllers optimize each panel individually—so even in partial shade, your array stays efficient. Ideal for shadow-prone setups, it prevents energy loss and keeps your power flowing.

FAQ
How do I connect multiple solar panels to my system? Should I use a serial or parallel configuration?
S1 supports parallel or series. No quantity limit in parallel, series: up to 3 S1 in series at the same time. As long as it's under 50V&450W.
Can I mix different solar panels?
Yes. Combine panels of any brand, wattage, or type. S1’s distributed MPPT ensures each panel performs at its maximum, eliminating compatibility issues.
How do I install the SolexBrick S1 controller?
Simply connect each SolexBrick S1 directly to a solar panel via MC4 connectors—no expertise required. The 3-step setup (attach S1 to panel, link panels, connect to battery) takes minutes. No bulky central controller or complex wiring is needed.
What are the advantages of Optisolex MPPT technology?
MPPT advantages: S1's 4-channel design boosts reliability and stability, InstantMax ensures real-time peak efficiency, panel optimization maximizes output under shade, and intelligent system sync connects units seamlessly.
