Solar charge controller with ultra-fast Maximum Power Point Tracking (MPPT). Detection of the Maximum Power Point even in partial shading. Load output and flexible charging algorithms. Overheating protection and load reduction at high temperatures. Automatic battery voltage detection and intelligent battery management through load shedding. Maximized efficiency. By continuously monitoring the voltage and current output of your solar panels, the technology of the BlueSolar MPPT ensures that all available energy is extracted from the modules and stored. The advantage is particularly noticeable in partially cloudy skies and varying light intensity.
Remote control via Bluetooth or the Internet. You can remotely control and monitor the extensive functions of your BlueSolar MPPT charger and pair it with your smartphone or another device via VictronConnect. If your system is connected to the Victron Remote Management Internet portal, you have full access to your MPPT anytime and anywhere. Both services are available free of charge.
Prevention of damage and excessive discharge. The intelligent load output prevents damage caused by using empty batteries. You can configure the voltage at which the BlueSolar charge controller disconnects a load to prevent excessive discharge of your batteries. The device attempts to recharge the battery to 100% every day. If this is not possible due to bad weather, it raises the voltage threshold for disconnection daily until it is successful.
