The Victron BlueSolar charge controller gets connected between the photovoltaic modules and the batteries allowing the product to increase energy harvest out of the modules as efficiently as possible.
Key Features 

Ultra-fast Maximum Power Point Tracking (MPPT)
Advanced Maximum Power Point Detection in case of partial shading conditions
Outstanding conversion efficiency with no fan cooling exceeding %98
Fully programmable charge algorithm with eight pre-programmed algorithms, selectable with a rotary switch
Extensive electronic protection
Internal temperature sensor
Real-time data display using VictronConnect application. 
3 Charging stages: Bulk - Absorption - Float



The Victron BlueSolar Charge Controller has an ultra-fast Maximum power point tracking (MPPT) controller that improves the energy harvest by 30% compared to PWM controllers and by up to 10% compared to the slower MPPT controllers. Especially in the clouded sky when the light intensity is changing continuously. 
The Victron BlueSolar Charge Controller uses the advanced Maximum Power Point Detection in cases of partial shading conditions. at times of partial shading happens two or more maximum power points can be presented on the power-voltage curve. Conventional MPPTs tend to lock to a local Maximum Power Point (MPP), which may not be optimum; however, the innovative BlueSolar algorithm will always maximize the energy harvest by locking to the optimum MPP.
This Victron BlueSolar charge controller comes with the remote management possibility using your smartphone or other Bluetooth-enabled devices. This feature can be used to control, monitor, and update the system wirelessly in the comfort of your home using the VictronConnect application (you will need a Bluetooth dongle). You also be connected directly to a Color Control GX, computer, or other devices.
The BlueSolar charger is equipped with an internal temperature sensor to compensate for the charging voltage according to its temperature. If the system temperature rises, the controller’s Extensive electronic protection will automatically reduce its output current (temperature >40°C). In addition to the mentioned protection systems, also this system is equipped with safety devices against overheating, short circuits, polarity reversal, and module current reversal.
