A solar charger gathers energy from your solar panels, and stores it in your batteries. Using the latest, fastest technology, SmartSolar maximises this energy-harvest, driving it intelligently to achieve full charge in the shortest possible time. SmartSolar maintains battery health, extending its life.

The Victron SmartSolar 100 VOC, 20 Amp MPPT solar panel charge controller can be used for 12V and 24V battery systems (including Lithium). It has in-built BlueTooth functionality so that you can control and monitor it's features via the Victron Connect App.


- Stage One - Bulk or Boost - As much current as possible is delivered in order to rapidly recharge the batteries to about 80%.
- Stage Two - Absorption - When the battery reaches its final charging voltage, known as its absorption voltage the charge allows the current to taper off as the battery nears a full charge.
- Stage Three - Float - At this stage float voltage is applied which is enough to retain a full charge but controlled to prevent overcharging.

MPPT: ULTRA FAST MAXIMUM POWER POINT TRACKING: By constantly monitoring the voltage and current output of your solar (PV) panels, MPPT technology ensures that every drop of available power is rinsed out of your panels, and harvested for storage. The advantage of this is most noticeable when the sky is partially clouded, and light intensity is constantly changing.

REMOTE MONITORING AND CONTROL: Remotely control and monitor the extensive features of your SmartSolar MPPT charger with built-in bluetooth by pairing it with your smartphone or other device via VictronConnect. If your installation is connected to the internet Victron Remote Management Portal (VRM) provides access to the full power of your MPPT, anytime, anywhere; both services are free to use. For remote installations - even when there is no internet connection or phone signal nearby - you may be able to monitor your MPPT by bluetooth-pairing with a LoRaWAN (long-range wide area network) device, available optionally.

LOAD OUTPUT: The intelligent Load output function prevents damage caused by running batteries 'flat'. You can configure the voltage at which SmartSolar disconnects a load - thereby preventing excessive drain on your batteries. And here's the clever bit: SmartSolar will attempt a 100% recharge every day. If it can't - during periods of poor weather - it raises the disconnect voltage, daily, until it achieves success. We call this feature Battery Life because it maintains the health, and extends the life of your battery.
