MPPT Solar Controller 30A from SRNE is a compact, all-in-one charging solution designed to protect your battery bank while extracting the maximum power from your solar array. Built for 12V and 24V systems, this regulator automatically identifies the system voltage and optimizes charging to deliver safer, smarter, and more efficient solar energy management.

Powerful MPPT technology that actually delivers

Backed by PowerCatcher MPPT technology, the regulator tracks the solar power point even in challenging lighting and shading conditions. This means faster response, higher tracking efficiency, and up to 15–20% more energy harvested compared with traditional PWM charging. The MPPT tracking efficiency can reach up to 99.9%, so you get the most out of every ray of sun.

Smart charging that protects and extends battery life

The controller includes automatic charging voltage regulation, ensuring safe charging even when the battery experiences open-circuit conditions or BMS overcharge protection. It automatically outputs the rated charging voltage to the battery when needed, and uses temperature-compensated charging to extend battery life. A temperature compensation function adjusts charging parameters to match ambient conditions, helping batteries last longer in extreme heat or cold.

Versatile battery compatibility and intelligent protection

Designed to support a range of chemistries, including lithium, gel, sealed (AGM), and vented lead-acid batteries. It also features a limited current charging mode—if panel power pushes beyond the rated current, the controller automatically scales back to the safe, rated level. Built-in protections cover:

• Solar panel short-circuit protection
• Battery open-circuit protection
• Overheat protection with linear current reduction and discharging shut-off to prevent damage
• TVS lightning protection and general electrical safeguards

Automatic identification of lead-acid battery voltage helps the unit choose the correct charging profile without manual setup.

Connectivity, control, and integration

This SRNE controller can be paired with an LCD screen or Bluetooth module for real-time monitoring and parameter tuning, so you’re not guessing about voltage, current, or state of charge. It also supports standard Modbus communication for integration into broader energy management systems, plus RS232 for direct data exchange. The modular approach makes it suitable for a wide range of off-grid installations—from small cabins to boats and RVs.
