Fuhuihe 40A MPPT Solar Charge Controller 12V/24V Solar Panel,Support Off-Grid Solar Power Systems

With the advanced dual-peak or multi-peak tracking technoloy,when the solar panel is shadowed or part of the panel fails resulting in multiple peaks on the I-V curve,The solar charge controller can still accurately track the maximum power point.
Built-in algorithm for maximum power tracking. significantly raises energy utilization efficiency of photovoltaic systems, with charging efficiency 15% ~ 20% higher than traditional PWM solar charge controllers.
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%.
Advance digital power supply technologies raise the circuits 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.
