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.Features.Ultra-fast Maximum Power Point Tracking (MPPT).Especially in case of a clouded sky, when light intensity is changing continuously, an ultra-fast MPPT controller will improve energy harvest by up to 30% compared to PWM charge controllers and by up to 10% compared to slower MPPT controllers.Advanced Maximum Power Point Detection in case of partial shading conditions.If partial shading occurs, two or more maximum power points (MPP) 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 maximize energy harvest by locking to the optimum MPP.Outstanding conversion efficiency.No cooling fan.Maximum efficiency exceeds 99%.Flexible charge algorithm.Fully programmable charge algorithm, and eight preprogrammed algorithms, selectable with a rotary switch (see manual for details).Extensive electronic protection.Over-temperature protection and power derating when temperature is high.PV short circuit and PV reverse polarity protection.PV reverse current protection.Internal temperature sensor.Compensates absorption and float charge voltage for temperature.Optional external battery voltage, temperature and current sensing via Bluetooth.A Smart Battery Sense or a BMV-712 Smart Battery Monitor can be used to communicate battery voltage and temperature (and current, in case of a BMV 712 or a SmartShunt) to one or more BlueSolar Charge Controllers.(VE.Direct Bluetooth Smart dongle needed).VE.Can:the multiple controller solution.Up to 25 units can be synchronised with VE.Can.VE.Direct or VE.Can.For a wired data connection to a Color Control GX, other GX products, PC or other devices.Remote on-off.To connect for example to a VE.BUS BMS.Programmable relay.Can be programmed to trip on an alarm, or other events.Optional:SmartSolar pluggable LCD display.Simply remove the rubber seal that protects the plug on the front of the controller, and plug-in the display.
