Thank you for selecting this solar charge controller. This solar charge controller is an advanced solar
charger with maximum power point tracking. Applying intelligent MPPT algorithm, it allows solar charge
controller to extract maximum power from solar arrays by finding the maximum power point of the array.
The MPPT battery charging process has been optimized for long battery life and improved system performance.
Self-diagnostics and electronic error protections prevent damage when installation errors or system faults
occur. This charger also features multifunctional LCD with communication ports for remote battery
temperature and voltage measurement.
