Solar cell maximum power point tracking (MPPT)
PWM buck mode, 12V lead-acid battery charge management IC, independent of the lead-acid battery charging for automatic management, with a small package, small external components and the use of simple and so on.
With trickle, constant current, overcharge and floating charge mode, very suitable for 12V lead-acid battery charging.
In the overcharge and floating charge mode, the charge voltage typical values ​​are 14.8V and 13.55V, respectively;
In constant current charging mode, the charge current is set by an external resistor. When using the solar panel power supply, the internal circuit can automatically track the maximum power point of the solar panel, the user does not need to consider the worst case, can maximize the use of solar panels output power, very suitable for the use of solar panel power supply applications.
If the battery voltage is less than 75% of the set overcharge voltage, 17.5% of the constant current charging current is used to trickle the battery. In the overcharge phase, the charging current gradually decreases, when the charging current is reduced to 38% of the constant current charging current, into the floating charge state. In the floating charge state, if the battery voltage drops to 83.95% of the set overcharge voltage, the new charge cycle is automatically started.
When the input power is off or the input voltage is lower than the battery voltage, automatically enter the low-power sleep mode. Other features include input low voltage latch, battery side overvoltage protection and charge status indication.
Package Included:
1x MPPT Solar Panel Controller Charging Module
