Product details:

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%.. Key Features Automatically detects 12V/24V DC system voltages High tacking efficiency of 99% Peak Conversion efficiency of 98% 4-stage charging with MPPT output Extensive electronic protections Diverse load control LCD screen with programmable charging parameters Charging data with storage of up to 1 year Die-cast aluminum design for heat dissipation Specifications Nominal system voltage :12V/24V Auto Recognition Rated Battery Current :20A Rated Load Current :20A Max.
