40A MPPT solar controller 12V/24V/48V auto-adaptive
- Automatic identification system voltage,12V/24V/48V auto recognition.
- Built-in MPPT (maximum power point tracking) algorithm,charging efficiency 15~20% higher than PWM types.
- With LED display,which can show the charging current and voltage.
- Reliable over charge protection,once it is under over-current protection the controller will automatically reduce the charge current.
- Reverse polarity protection of solar panel and battery.
- Three-stage charging optimizes battery performance.
