Solar Charge Controller SR ML 2420 MPPT 20A

With MPPT (Max Power Point Tracking), the full power of your solar modules is used optimally.

Ideal for using the full power (20-35% more solar power yield) of your solar module to charge your 12 or 24 volt solar batteries.

MPPT solar charge controller up to 20A charging current for 12V / 24V batteries. Max. PV voltage 100V, Max. PV power 280W/12V, 560W/24V.

More usable solar power through fast maximum power point tracking. Charging current up to 20A. Compatible with almost all module types thanks to the high PV input voltage of up to 100V. The controller automatically adapts to a 12V or 24V battery voltage.

Solar charge controller function

A solar charge controller regulates the voltage of the solar modules to an optimum level for the batteries. The charge controller automatically recognizes the nominal voltage of 12V or 24V. By using MPPT technology, the solar charger can generate up to 30% more energy from the solar panel into the battery compared to conventional chargers. Thanks to the three-stage charging characteristic with selectable charging voltages, the charge controller can be configured in such a way that the charging parameters are precisely set to the respective battery requirements.

MPPT (Max Power Point Tracking)

• Automatic system voltage detection 12/24V
• Solar input voltage range from up to 100V
• Battery deep discharge protection, overcharge protection, overvoltage protection
• Protection against desulfation
• Temperature-dependent charging parameter correction
• Over-temperature protection, over-current protection, polarity protection
• Separate load output with switch-off option

The system is fully protected against overvoltage, overtemperature and reverse polarity. An automatic current limit allows the full current to be used without the user having to worry about potential overload. When expanding the solar system, up to 3 controllers can be interconnected and thus process three times the charging current.
