MPPT Solar Charge Controller reviews 12V 24V LCD USB Regulator with Load Dual Timer Control for Solar Lighting System
40A T40Solar Charge Controller Dual timer
The MPPT T40 is upgrade of MPPT40. It is the second generation MPPT40.The biggest difference between the two model solar controllers is that the MPPT T30 is light and dual timer control.
This is a three-time controller into the evening working time,an interval of rest of pause time,Dawn working time(morning light function), the user can according to their needs,set a different time.
A:time(evening working) B:time(pause working) C:time(dawn working)
