30A MPPT, LCD Display 12/24V Auto Detect • With the advanced dual-peak or multi-peak tracking technology, when the solar panel is shadowed or part of the panel fails resulting in multiple peaks on the I-V curve, the controller is still able to accurately track the maximum power point. • A built-in maximum power point tracking algorithm can significantly improve the energy utilization efficiency of photovoltaic systems, and raise the charging efficiency by 15% to 20% compared with the conventional PWM method. • A combination of multiple tracking algorithms enables accurate tracking of the optimum working point on the I-V curve in an extremely short time. • The product boasts an optimum MPPT tracking efficiency of up to 99.9%. • Advanced digital power supply technologies raise the circuit’s energy conversion efficiency to as high as 98%. • Charging program options are available for different types of batteries including gel batteries, sealed batteries, open batteries, lithium batteries, etc. • The controller features a limited current charging mode. When the solar panel power exceeds a certain level and the charging current is larger than the rated current, the controller will automatically lower the charging power and bring the charging current to the rated level. • Instantaneous large current startup of capacitive loads is supported. • Automatic recognition of battery voltage is supported. • LED fault indicators and an LCD screen which can display abnormality information help users to quickly identify system faults. • Historical data storage function is available, and data can be stored for up to a year. • The controller is equipped with an LCD screen with which users can not only check device operating data and statuses, but also modify controller parameters.
