T10/T20/T30/T40 User Manual
This is a three-time controller into the evening (evening) working time, an interval of rest or
pause time, Dawn working time (morning light function), the user can according to their
needs, set a different time.
This is a compatible MPPT charge controller PWM intelligent / efficient / energy saving, he
not only has efficient MPPT controller charging function to automatically track the
maximum power point, 10% -30% higher than the ordinary controller charging efficiency,
also has standby energy saving, more than 30% energy than ordinary controller, the
standby power consumption of only 10mA-15mA.
