In the world of off-grid solar, "one size fits all" is a myth. While many controllers claim high efficiency, the real-world performance depends on how well the hardware matches the specific demands of your project. At SUNOPEN, we've engineered our 99.9% tracking efficiency into three distinct families to solve unique challenges.
The Hybrid Specialist (MPPT + ATS)
For critical infrastructure like CCTV security cameras or IoT gateways, power failure is not an option. Our A Series is the industry's first to integrate an Automatic Transfer Switch (ATS). It seamlessly toggles between solar and a DC power adapter, ensuring 24/7 uptime even during a week of rain.
The Industrial Workhorse (Step-Down)
Designed for stability in large-scale projects, the M Series covers everything from 12V garden lighting to massive 48V industrial battery banks. With the M24/M48 Variable Voltage models, you get professional-grade flexibility and support for 30A charging currents.
The Mobility Innovator (Boost Type)
Standard chargers can't handle low-voltage panels charging high-voltage batteries. Our H Series Boost MPPT (450W/800W) changes the game for E-vehicles, RVs, and Yachts. It can take solar input and boost it to charge 48V, 60V, or 72V battery platforms.

The Intelligence Layer: Smart Monitoring
A controller is only as good as the data you can get from it. By pairing any SUNOPEN controller with our NET Series (4G/WiFi/Ethernet) or BL01 Bluetooth modules, you gain real-time visibility through our dedicated App and Web Portal. Adjust parameters, monitor battery health, and receive fault alerts anywhere in the world.
