Victron BlueSolar MPPT MC4 150/70 12/24/36/48V
The Victron BlueSolar MPPT 150/70 12/24/36/48V solar charger collects energy from your solar panels and stores it in your batteries. With the latest and fastest technology, BlueSolar 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 lifespan.

Victron BlueSolar MPPT MC4 150/70 12/24/48V is a solar charger for 12V, 24V, 36V or 48V systems (12/24/48V autoselect). The maximum nominal PV power transmitted by the solar charger at a 12V system voltage is 650W, at a 24V system voltage it is 1300W, at a 36V system voltage it is 1950W, and at a 48V system voltage it is 2600W. The maximum PV no-load voltage of this solar charger is 150V. The BlueSolar solar charge controllers have a programmable battery charging algorithm. To set up the solar charger, a Victron VE.Direct Bluetooth Smart dongle or a Victron VE.Direct to USB interface cable is required.

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 yield 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 changing shade
In the case of varying shading, 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 energy yield by utilizing the optimal MPP.

BatteryLife: intelligent battery management
If a solar charge controller cannot fully recharge the battery in one day, the result is often that the battery constantly fluctuates between 'partially charged' and 'fully discharged'. This condition (no regular full charge) will cause a lead-acid battery to become irreparably damaged within weeks or months. The BatteryLife algorithm monitors the battery's state of charge and, if necessary, increases the load disconnection level slightly from day to day (by disconnecting the load earlier) until the harvested solar energy is sufficient to charge the battery to almost full 100% to charge. From then on, the load disconnect level is modulated so that the battery is charged to almost 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 charging 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 charging 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.
