Victron SmartSolar MPPT 250/85-MC4
The Victron SmartSolar MPPT 250/85-MC4 solar charger collects energy from your solar panels and stores it in your batteries. With the latest and fastest technology, SmartSolar maximizes this energy harvest through intelligent control, so that a full charge is achieved in the shortest possible time. SmartSolar keeps the battery in good condition and thus extends its life.

Victron SmartSolar MPPT 250/85 is for 12 / 24 / 48V Auto Select (software tool needed to select 36V) systems. The maximum nominal PV power that is passed through the solar charger at a 12V system voltage is 1200W, at a 24V system voltage it is 2400W and at a 48V system voltage it is 4900W. The maximum PV no-load voltage of this solar charger is 250V. The SmartSolar solar charge controllers have a programmable battery charging algorithm, and built-in standard Bluetooth Smart to set up the solar charger and monitor solar yield. The controller is equipped with two sets of MC4 plugs for connecting the solar panels.

Bluetooth Smart built-in: no dongle required
The wireless solution to set up, monitor and update the controller via Apple or Android smartphones, tablets or other devices.

VE.Direct
For a wired data connection to a Color Control panel, Venus GX, PC or other devices.

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 harvest by up to 30% compared to PWM charge controllers and up to 10% compared to slower MPPT controllers.

Advanced Maximum Power Point Detection in case of varying shade
In the case of varying shade, the power-voltage curve may contain two or more maximum power points. Conventional MPPTs usually utilize local MPP, which may not be the optimal MPP. The innovative BlueSolar algorithm always maximizes the energy yield by exploiting the optimal MPP.

BatteryLife: intelligent battery management
If a solar charge controller cannot fully charge the battery in one day, the result is often that the battery fluctuates continuously between 'partially charged' and 'fully discharged'. This condition (not a regular full charge) will destroy a lead-acid battery within weeks or months. The BatteryLife algorithm monitors the state of charge of the battery and, if necessary, slightly increases the load disconnect level from day to day (by disconnecting the load earlier) until the harvested solar energy is sufficient to charge the battery to almost 100%. to charge. From then on, the load disconnect level is modulated so that the battery is charged to nearly 100% about 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 charge 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.

Remote on-off
For example for connection to a VE.BUS BMS.

Programmable relay
Can be programmed (e.g. via a smartphone) to be activated by an alarm or other events.

Optional: linkable LC display
To do this, remove the rubber seal that protects the plug on the front of the controller and connect the display to it.
