Description
Charge controller
Maximum Power Point Tracking (MPPT)
SR-ML series
40A
12/24V auto work
SR-ML series 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.
- Improve the energy utilization efficiency of photovoltaic systems
- Raise the charging efficiency by 15% to 20% compared with the conventional PWM method.
- Built-in running date and event logging
- The product boasts an optimum MPPT tracking efficiency of up to 99.5%.
- Instantaneous large current startup of capacitive loads is supported.
- Multiple load control modes
