MPPT 100/15 Smart Solar Charge Controllers with Load Output, 15A (12/24V DC)

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.

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 BatteryLife because it maintains the health, and extends the life of your battery.

What size MPPT should I buy?
How to size your MPPT can be confusing, which is why Victron has developed a sizing calculator . To use it, you’ll need some information that should be displayed on the back of your solar panels. Please note – when filling out the “PV Module Temperature” min/max – you are advised to use the coldest date on record for the regions you plan to cruise in. The MPPT controller you need is based largely on the maximum Voc (voltage over circuit) which is impacted by operating temperatures. Since Voc increases as temperature decreases, it’s very important to know the coldest potential operating temperature.  And while it’s okay to oversize your MPPT, an undersized MPPT will fail if the Voc gets too high – so if there’s any doubt, upsize!
