40ah MPPT Solar Charge Controller.

It regulates the voltage and current from solar panels to safely charge and maintain batteries. The device features an LCD display for real-time updates on charging status, voltage, and system performance. MPPT technology allows solar panels to operate at their optimum power output voltage, which can improve their performance by as much as 30%. It supports automatic detection of system voltage (e.g., 12V/24V) and multiple battery types.
