MAX20-EU
20A PWM SOLAR CHARGE CONTROLLER
PWM, 20A/20A, 12V/24V auto,
LCD display, 5V2A USB*2, IP32
- LCD display design, read operating data and working condition easily.
- Real-time energy statistics function.
- 12V/24V automatic recognition
- AGM,Liquid and GEL battery for selection.
- External temperature sensor, automatic temperature compensation.
- Built-in temperature sensor, when the temperature exceeds the set value, the charging current will lower down followed by the decrease of temperature, so as to control the controller’s temperature rise.
- Four stages charge way: fast, boost, equal, float.
- Multiple load control modes: Standard, Dusk to Dawn, Timer and User-defined mode.
- Two USB interfaces.
- Perfect EMC & thermal design.
