The Solarthon MPPT Solar Charge and Discharge Controller is an advanced charging method that utilizes maximum power point tracking (MPPT) technology. This controller is designed to monitor the power generation voltage of the solar panel in real time and track the highest voltage and current values. By doing so, it maximizes the power output and ensures efficient charging of the battery.
Unlike other controllers, the maximum power point tracking mode of this series is completely automatic and does not require any user adjustment. It intelligently tracks the maximum power point of the solar panel, adapting to changing environmental conditions. This guarantees the extraction of maximum energy from the solar array.
