With advanced dual-peak or multi-peak tracking technology, the solar charge controller can accurately track the maximum power point when the solar panel is shaded or part of the panel fails, resulting in multiple peaks on the I-V curve. Built-in algorithm for maximum energy tracking. significantly increases the energy use efficiency of photovoltaic systems, with charging efficiency 15% ~ 20% higher than conventional PWM solar charge controller. A combination of multiple tracking algorithms enables accurate tracking of the optimal operating point on the I-V curve in an extremely short time. The product has an optimal MPPT tracking efficiency of up to 99.9%. Advanced digital power technologies increase the efficiency of circuit conversion up to 98%. Charger options are available for different battery types, including gel batteries, sealed batteries, open batteries, lithium batteries, etc. specifications: System voltage: 12V / 24V car Battery voltage: 9V to 35V Max.
