Authorised Victron Energy Installer
1 / 6A solar charger gathers energy from your solar panels, and stores it in your batteries. Using the latest, fastest technology, BlueSolar maximises this energy-harvest, driving it intelligently to achieve full charge in the shortest possible time. BlueSolar maintains battery health, extending its life.

The Victron SmartSolar MPPT 100/30 is a 30 A solar charge controller for 12 V or 24 V batteries. It takes a maximum PV open circuit voltage of 100 V and a maximum PV short circuit current of 35 A. The default charge voltage is 14.4 V absorption and 13.8 V float on a 12 V battery, and you can adjust both.
We fit a DC isolator between the panels and the controller on every system. Our guide explains whether you need a DC isolator for solar. The full figures are in Victron's SmartSolar MPPT 100/30 datasheet.
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.

Advanced Maximum Power Point Detection in case of partial shading conditions
If partial shading occurs, two or more maximum power points may be present on the power-voltage curve. Conventional MPPTs tend to lock to a local MPP, which may not be the optimum MPP. The innovative BlueSolar algorithm will always maximise energy harvest by locking to the optimum MPP.
Outstanding conversion efficiency
No cooling fan. Maximum efficiency exceeds 98%.
The full output current up to 40°C (104°F).
Flexible charge algorithm
Fully programmable charge algorithm (see the software page on our website), and eight pre-programmed algorithms, selectable with a rotary switch (see manual for details).
Solar, battery monitoring and remote access together.

The first is the maximum PV open-circuit voltage, the second is the maximum charge current. A 100/30 takes up to 100 V from the panels and charges at up to 30 A.
The table shows nominal PV power at 12 V from the Victron datasheet. If more is connected, the controller limits input power.
Yes. SmartSolar controllers have Bluetooth and are set up in the VictronConnect app.
