The CMLmppt charge controller is equipped with a number of outstanding features such as a status indication, alarm, and safety functions. The temperature compensated, four-stage charging algorithm (float-main-boost-equalization) is adjustable for sealed and vented lead-acid batteries. The CMLmppt charge controller also allows either a SOC or voltage-controlled low-voltage disconnect. The use of MPPT technology can contribute to a considerable boost in energy output from PV modules (up to 30% more), especially in moderate/colder climate areas where PV module voltages tend to be higher. Battery status is clearly indicated by three LEDs. An acoustic alarm warns about an impending low-voltage disconnect (LVD).
