Victron BlueSolar MPPT 100/20 12 / 24V is a solar charger for 12V or 24V systems (autoselect). The maximum nominal PV power that is passed through the solar charger with a 12V system voltage is 290W, and with a 24V system voltage it is 580W. The maximum PV open circuit voltage of this solar charger is 100V. The BlueSolar solar charge controllers have a programmable battery charging algorithm.

Ultra-fast Maximum Power Point Tracking (MPPT)
Especially when it is cloudy and the light intensity is constantly changing, an ultra-fast MPPT controller improves energy yield up to 30% compared to PWM charge controllers and up to 10% compared to slower MPPT controllers.
BatteryLife: intelligent battery management
If a solar charge controller cannot fully recharge the battery in one day, the result is often that the battery is constantly fluctuating between “partially charged” and “fully discharged”. This condition (not regular full charging) will destroy a lead-acid battery within weeks or months. The BatteryLife algorithm monitors the battery’s state of charge and increases the load disconnect level slightly from day to day if necessary (by disconnecting the load earlier) until the harvested solar energy is sufficient to drive the battery to almost full 100%. to charge. From then on, the load disconnect level is modulated so that the battery is almost fully charged to 100% approximately once a week.
Programmable battery charging algorithm
Every morning, as soon as the sun starts to shine, the charge controller starts a new charge cycle based on a three-step charging process: Bulk – Absorption – Float. The battery charging algorithm is programmable with a set of default settings or user-defined settings.
Internal temperature sensor
Compensates absorption and float charge voltages for temperature.
Over-discharge of the battery can be prevented by connecting all loads to the load output. The load output disconnects the load when the battery is discharged to a preset voltage. (48V model: interface with a relay) Alternatively, the BatteryLife intelligent battery management algorithm can be selected. The load output can be configured via Bluetooth or via VE.Direct and is short circuit proof.
Day / night timing and light dimming option
The Streetlight function allows you to automatically control the night lighting, timing and dimming option. When the Street lighting function is enabled, a timer program can be created using ‘sunset’ and ‘sunrise’ as anchor points for the timer program. The advantage of this is that the program adapts to the duration of the night because it changes with the season.
