Autosolar Compact Solar Charge Controller MPPT 20A

MPPT Charging Technology

With MPPT (Maximum Power Point Tracking), the full power of your solar panels is optimally utilized. It is ideal for maximizing the output of your solar panels and charging your batteries at 12V/24V volts.

The MPPT solar charge controller can deliver up to 20A charging current for 12V and 24V batteries. The maximum PV voltage is 100V, and the charge controller can handle up to 260W at 12V and up to 520W at 24V.

The charge controller can be used for lead, AGM, gel, and lithium batteries. If needed, you can also create a battery charging profile according to your preferences.

Function of the Solar Charge Controller

The solar charge controller regulates the voltage of the solar modules to an optimal level for the batteries. The nominal battery voltage is automatically detected by the charge controller. By applying MPPT technology, the charge controller can achieve up to 30% more energy yield from the solar module into the battery compared to conventional charge controllers (PWM). With the three-stage charging characteristic and selectable charging voltages, the charge controller can be configured to precisely match the charging parameters to the specific battery requirements.

MPPT (Maximum Power Point Tracking)

Automatic system voltage detection

Solar input voltage range of up to 100V

Battery deep discharge protection, overcharge protection, overvoltage protection

Protection against desulfation

Temperature-dependent charging parameter correction

Overtemperature protection, overcurrent protection, polarity protection

The system is fully protected against overvoltage, overheating, and reverse polarity. An automatic current limit allows the use of the full current strength without the user having to worry about potential overload. When expanding the solar system, up to 3 controllers can be connected in parallel, allowing for three times the charging current capacity.
