solar charge controllers

Solar chargers collect energy from your solar panels and store it in your batteries. Using the latest and fastest technology, SmartSolar maximizes this energy harvest, managing it intelligently to reach maximum charge in the shortest possible time. The SmartSolar takes care of the health of the battery, extending its useful life.


The SmartSolar Charge Controller will recharge even an extremely depleted battery. It can work with a battery voltage down to 0 volts, as long as the cells are not leaked or permanently damaged


MPPT: Ultra-fast tracking of the Maximum Power Point

Thanks to the continuous monitoring of the output voltage and current of your solar (PV) panels, the MPPT technology (Ultra-fast Maximum Power Point Tracking) guarantees the collection and storage of every particle of energy available in your panels. The advantage of this process becomes more apparent when the sky is partly cloudy and the light intensity is constantly changing.


Remote monitoring and control

Remotely monitor and control the multitude of features of your SmartSolar MPPT charger by adding a Bluetooth dongle and syncing with your smartphone or other device using VictronConnect. If your installation is connected to the Victron Remote Management (VRM) Portal, you will also have access to the full power of your MPPT, anytime, anywhere; both services are free. In the case of remote installations, even when there is no internet connection available, you can monitor your MPPT by connecting the GlobalLink 520.


load output

The intelligent Charge Output function prevents the damage that occurs when a battery goes "empty". You can configure the voltage at which the SmartSolar must disconnect the load, thus avoiding excessive draining of your batteries. And here's the neat trick: SmartSolar will try to recharge the battery to 100% every day. If it cannot do so, such as during periods of bad weather, it will raise the disconnect voltage daily until it succeeds. We call this feature BatteryLife, because it maintains the health of your battery and extends its life.

  • The Differences of PWM and MPPT Regulators

    What solar regulator do I need according to the type of solar panel?

    Normal regulator (PWM): Whether you have 12V solar panels to use in a 12V isolated (or autonomous) solar installation, such as if you have 24V solar panels and 72 cells for use in a 24V installation, you must use a normal regulator (PWM type). Which is the most economical and suitable for this type of solar panel.

    Maximizing Controller (MPPT): If you have 24V and 60-cell solar panels (power panels greater than 200W), to use in an isolated 24V solar installation, you must use an MPPT maximizer regulator. Necessary to amplify the voltage of these solar panels, so that when it reaches the batteries it is high and the energy is stored well. The MPPT regulator is more expensive but it is necessary with this type of boards. Which without the use of the MPPT, the useful life of the batteries would be damaged since it could not be equalized and would sulphate in a few months.
