Victron Energy BlueSolar MPPT 75/15

Solar charge controller
A 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.

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 BlueSolar MPPT charger by attaching a Bluetooth dongle and pairing it with your smartphone or other device via VictronConnect. If your installation is connected to the internet with a GX device, the Victron Remote Management Portal (VRM) provides access to the full power of your MPPT, anytime, anywhere; both VictronConnect and VRM are free to use. For remote installations - even when there is no internet connection nearby - you may be able to monitor your MPPT by connecting the GlobalLink 520.

Load output
The intelligent Load output function prevents damage caused by running batteries 'flat'. You can configure the voltage at which BlueSolar disconnects a load - thereby preventing excessive drain on your batteries. And here's the clever bit: BlueSolar 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.

1a) If more PV power is connected, the controller will limit input power.
1b) The PV voltage must exceed Vbat + 5V for the controller to start.
Thereafter the minimum PV voltage is Vbat + 1V
2) A PV array with a higher short circuit current may damage the controller.
