Victron BlueSolar

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.
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.
