Victron Energy SmartSolar MPPT 100/20

A solar charger gathers energy from your solar panels, and stores it in yourbatteries. Using the latest, fastest technology, SmartSolar maximises thisenergy-harvest, driving it intelligently to achieve full charge in the shortestpossible time. SmartSolar maintains battery health, extending its life.The SmartSolar charge controller will even recharge a severely depleted battery.It can operate with a battery voltage as low as 0 Volts, provided the cells arenot permanently sulphated or otherwise damaged.By constantly monitoring the voltage and current output of your solar (PV)panels, MPPT technology ensures that every drop of available power is rinsed outof your panels, and harvested for storage. The advantage of this is mostnoticeable when the sky is partially clouded, and light intensity is constantlychanging.Remotely control and monitor the extensive features of your SmartSolar MPPTcharger with built-in Bluetooth by pairing it with your smartphone or otherdevice via VictronConnect.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 periodsof poor weather - it raises the disconnect voltage, daily, until it achievessuccess. We call this feature BatteryLife because it maintains the health, andextends the life of your battery.Features-Bluetooth Smart built-in-Ultra-fast Maximum Power Point Tracking (MPPT)-Load output-Battery Life: intelligent battery management-Programmable battery charge algorithm-Day/night timing and light dimming option-Internal temperature sensor-Optional external battery voltage and temperature sensing via Bluetooth-Fully discharged battery recovery functionSpecifications-Battery voltage (auto select): 12/24/48V-Rated charge current: 20A-Nominal PV power, 12V: 290W-Nominal PV power, 24V: 580W-Nominal PV power, 48V 1a,b): 1160W-Automatic load disconnect: Yes-Max.
