Bluetooth Smart built-in:The wireless solution to set-up, monitor, update and synchronise SmartSolarCharge Controllers.Ultra-fast Maximum Power Point Tracking (MPPT):Especially in case of a clouded sky, when light intensity is changingcontinuously, an ultra-fast MPPT controller will improve energy harvest by up to30 % compared to PWM charge controllers and by up to 10 % compared to slowerMPPT 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 presenton the power-voltage curve. Conventional MPPTs tend to lock to a local MPP,which may not be the optimum MPP. The innovative SmartSolar algorithm willalways 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 (see the software page on our website), andeight preprogrammed algorithms, selectable with a rotary switch (see manual fordetails).Extensive electronic protection:Over-temperature protection and power derating when temperature is high. PVshort circuit and PV reverse polarity protection. PV reverse current protection.Internal temperature sensor and optional external battery voltage andtemperature sensing via Bluetooth:A Smart Battery Sense, a BMV-712 Smart Battery Monitor or a SmartShunt can beused to communicate battery voltage and temperature (and current, in case of aBMV-712 or a SmartShunt) to one or more SmartSolar Charge ControllersSynchronized parallel charging with Bluetooth:Up to 10 units can be synchronized with Bluetooth.Fully discharged battery recovery function:Will initiate charging even if the battery has been discharged to zero volts.Will reconnect to a fully discharged Li-ion battery with integrated disconnectfunction.VE.Direct:For a wired data connection to a Color Control GX, other GX products, PC orother devicesRemote on-off:To connect for example to a VE.BUS BMS.Programmable relay:Can be programmed (a.o. with a smartphone) to trip on an alarm, or other events.Optional: SmartSolar pluggable LCD display Simply remove the rubber seal thatprotects the plug on the front of the controller, and plug-in the display.Features:Ultra-fast Maximum Power Point Tracking (MPPT).Advanced Maximum Power Point Detection in case of partial shading conditions.Outstanding conversion efficiency.Natural convection cooling.Automatic battery voltage recognition.Flexible charge algorithm.Over temperature protection and power derating when temperature is high.Specifications:Battery voltage: 12 / 24 / 48V Auto Select (software tool needed to select 36V)Rated charge current: 60ANominal PV power, 12 V 1a,b): 860WNominal PV power, 24 V 1a,b): 1720WNominal PV power, 36 V 1a,b): 2580WNominal PV power, 48 V 1a,b): 3440WMax.
