Smart-MPPT Li series intelligent MPPT solar controller is programmable and especially for solar light system. The charging efficiency is about 20% higher than the traditional PWM controller, which can make the cost of the whole system much lower.
Self Test:
As soon as the controller is supplied with battery, it starts a self test routine. Then the display changes to normal operation.
Battery Type :
The controller is applied to Lithium rechargeable battery . The charging voltage target and charging voltage recovery can be set according to customer requirements.The controller is suitable for 3~8 series lithium battery.(The nominal voltage of a single lithium battery is 3.7V and the charging voltage target is 4.2V).
