Victron Energy BlueSolar MPPT 100/20

A solar charger gathers energy from your solar panels, and stores it in yourbatteries. Using the latest, fastest technology, BlueSolar maximises thisenergy-harvest, driving it intelligently to achieve full charge in the shortestpossible time. BlueSolar maintains battery health, extending its life.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.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 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.PLEASE NOTE: BlueSolar MPPT Solar Charge Controllers does not have Bluetoothbuilt-in. If you require Bluetooth purchase the SmartSolar MPPT ChargeController. Only the SmartSolar MPPT Charge Controller has Bluetooth built-in.Features-Ultra-fast Maximum Power Point Tracking (MPPT)-Load output-Battery Life: intelligent battery managementSpecifications-Battery voltage (auto select): 12/24/48V-Rated charge current: 20A-Nominal PV power, 12V: 290W-Nominal PV power, 48V: 1160W-Max.
