2X 5A MPPT Solar Panel Regulator Controller Solar Charge Controller Battery Charging Module 9V 12V 18V 24V 300KHz PWM

2X 5A MPPT Solar Panel Regulator Controller Solar Charge Controller Battery Charging Module 9V 12V 18V 24V 300KHz PWM Description

Charge indicator: Yes. Fast charging red light long bright red and lights flash alternately charged. Full automatic stop.MPPT function: a. MPPT maximum power point automatic tracking, to maximize the full use of solar charging
mppt voltage: adjustable, MPPT solar modules in different voltage is different, even mppt voltage can not tune mppt solar controller, can be called mppt it? MPPT control technology using charge sheet charging efficiency ratio control scheme in general or a - step-down power MCU + PWM lift about 30%. Make full use of solar , and low-power operation. Reduce power loss! MPPT function can effectively prevent the solar panels so that the charging voltage is the battery slow slow death.
Low pressure: 1V (as is the step-down voltage regulator, the input voltage is at least higher than the output 1V)
Low power consumption: Yes! Ultra-low pressure designed to achieve low power consumption and high efficiency, professional adaptation of solar panels
Charging: automatic intelligent three-stage charging mode. Self-tracking solar power charge current automatically adjust the size.
