40A MPPT SRNE Shiner2440 Solar Charge Controller – 12V / 24V Auto

The 40A MPPT SRNE Solar Charge Controller – Shiner2440 is a high-efficiency solar charging solution designed to regulate and optimise battery charging in 12V and 24V solar power systems across Kenya.

Equipped with MPPT (Maximum Power Point Tracking) technology, the Shiner2440 intelligently tracks the optimal operating point of solar panels to maximise energy harvest, especially during low sunlight and variable weather conditions. With automatic system voltage detection, it seamlessly supports both 12V and 24V battery banks, making it ideal for flexible solar installations.

Designed for durability and accuracy, the controller protects batteries from overcharging, deep discharge, overload, and short circuits—ensuring long battery life and stable system performance. Supplied and supported by Macire, each unit is verified for authenticity, correct operation, and compatibility with locally used batteries and solar panels.
