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