Victron SmartSolar Controller 12/24V 50A MPPT 100/50 Bluetooth Smart built-in The wireless solution to configure, monitor, update and synchronize the SmartSolar charge controller. VE.Direct For a connected data link to a Color Control GX, other GX products, PC or other devices. Ultra-fast Maximum Power Point Tracking (MPPT) Especially in cloudy weather when the light intensity is constantly changing, the ultra-fast MPPT controller will improve energy absorption by up to 30% compared to PWM charge controllers and up to 10% compared to slower MPPT controllers. Advanced Max Power Point Detection in case of partial shading. If partial shading occurs, two or more maximum power points may appear on the power voltage curve. Traditional MPPT devices tend to lock to a local MPP, which may not be the optimal MPP. The innovative BlueSolar algorithm always maximizes energy uptake by locking to an optimal MPP Outstanding conversion efficiency No cooling fan. Maximum efficiency exceeds 98%. Full output current up to 40 C. Flexible charging algorithm Fully programmable charging algorithm and eight pre-programmed algorithms that can be selected with a rotary switch (see manual for further details). Comprehensive electronic protection Over-temperature protection and high temperature power reduction. Solar cell short circuit protection and reverse polarity protection. Solar back current protection. Internal temperature sensor Compensates absorption and float charge voltage for temperature. Additional external battery voltage and temperature sensing via Bluetooth A Smart Battery Sense or a BMV-712 Smart Battery Monitor can be used to communicate battery voltage and temperature to one or more SmartSolar charge controllers. Additional external battery voltage and temperature sensing via Bluetooth A Smart Battery Sense or a BMV-712 Smart Battery Monitor can be used to communicate battery voltage and temperature to one or more SmartSolar charge controllers. Recovery function for fully discharged batteries Starts charging even when the battery has been discharged to zero volts. Reconnects to a fully charged Li-ion battery with an internal disconnect function.
