Audited Supplier 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 ensures that the battery is charged with the maximum power output, resulting in efficient energy extraction from the solar array.
The MPPT mode of this controller is fully automatic, eliminating the need for user adjustment. It automatically tracks the maximum power point of the solar panel, which varies with environmental conditions, to optimize energy extraction.
