Maximum power point tracking (MPPT) of solar cells is to ensure that photovoltaic cells always output maximum power when the light intensity changes, so as to make full use of solar energy.
In general, the MPPT functionneeds to be realized by using a switch-mode DC-DC converter to maximizethe product (output power) of the output voltage and the charging current. The maximum power point tracking function of photovoltaic cells is realized by switching step-down mode DC-DC conversion. Its input voltage canreach up to 28V, which is very suitable for applications with large difference between input voltage and battery voltage.
High-end MPPT solar maximum power tracking charging management chip, with trickle-flow, constant-current and constant-voltage charging management
Adopt imported high frequency and low on-off internal resistance double MOS tube, large current diode, high efficiency flat high power inductor, alloy current detection resistor
Super large aluminum heat sink at the bottom to ensure the long time stable operation oflarge current
High speed and efficient charging methodDual status indicator: the red light flashes and the green light is always on when the battery is not connected, and the red light is on when the battery is charging, and the green light is on at the same time when the batteryis full stop
