White Mppt 60 150 Solar Charge Controller 12 Volt Solar Panel Regulator
Features of SR-ML4860
1. Can be used in all kinds of bad environment with Aluminum frame.
 2. Double crest or multi crest tracing technique design, when the solar panel is under shadow or part of the solar panel is damaged, multi crest will turn up in I-V curve, and the controller can still trace the Max. Power Point.
 3. Built-in maximum power point tracking algorithm which could promote energy utilization efficiency of pv system. The charging efficiency is 15%~20% higher than PWM mode.
 4. Adopting sorts of tracking algorithm to track the best working point of I-V curve promptly and accurately within 15 seconds, the MPPT efficiency could reach to 99.9%.
 5. The use of advanced digital power technology, circuit energy conversion efficiency is as high as 96%
 6. Four stage charging order mode: MPPT-equalizing charging-boost charging-float charging.
 7. With current-limiting charging mode, when the power of solar panel is over-sized and charging current exceeds the rated current, the controller will lower the charging power, which enables the system to work under the rated charging current.
