Victron BlueSolar 75/15 MPPT
Robust and fast MPPT controller for demanding conditions with panel voltage up to 75 V , maximum charging current 15 A. Battery 12/24 V , PV max. 220/440 Wp .
Ultra-fast Maximum Power Point Tracking (MPPT)
Victron Energy MPPT solar controllers are among the absolute world leaders in this field. They offer ultra-fast MPPT tracking, which ensures maximum possible solar gains. Especially under cloudy skies with frequent changes in the intensity of illumination, solar gains are 30% higher compared to classic PWM controllers or 10% higher compared to slower MPPT controllers.
The maximum power of solar panels is 220 Wp for 12 V systems, 440 Wp for 24 V systems . If these values are exceeded, the controller will not be damaged, but will only automatically reduce the power coming from the panels to acceptable values. The solar controller is factory preset and there is usually no need to make any major adjustments to the settings.
The maximum open circuit voltage (referred to as Voc) of the connected solar panels must not exceed 75 V (note: the voltage of the solar panels increases as the outdoor temperature decreases). The maximum input short circuit current of the PV panels must not exceed 15 A , otherwise permanent damage may occur.
You can check the correct selection of your MPPT controller (BlueSolar/SmartSolar) according to the parameters of the PV array in this configurator or in a newer version, which can be found at www.victronenergy.com/support-and-downloads/software .
The BlueSolar MPPT controller series allows the connection of an external Bluetooth adapter called Smart Dongle:
This external BT adapter allows you to connect your smartphone/tablet (VictronConnect app) to your solar controller. You can monitor many system parameters and historical statistics for the last 30 days. You can also set operating parameters.
If you want to do the above using a PC, you can use the VE.direct to USB cable to connect the controller to the PC. Simply install the Victron Connect program on your computer.
The internal electronic components are protected by a resin coating against adverse influences and for long life. It offers increased resistance to IP43 for electronic components and IP22 for connection connectors. Designed for vertical position on a non-flammable surface, with wiring from below.
The controller contains an internal temperature sensor for appropriate adjustment of the charging voltage. Automatic detection of system voltage 12 or 24 V.
Adaptive three-stage charging:
1. fast charging (Bulk), 2. absorption (Absorption) and 3. maintenance (Float). Initially, during fast charging, a high current and lower voltage are generated to quickly recharge a discharged battery. This phase is followed by a constant voltage with a decrease in current to fully charge the battery without dangerous overcharging, which reduces the battery life. The charged battery is maintained in a charged state by a very low current and low voltage. If the voltage on the battery drops below 13.2 V, for example due to a load, a new charging cycle is started.
The voltage from the panels must exceed the battery voltage by 5 V for the regulator to start working.charge the battery. The controller charges until the voltage from the panels is 1 V higher than the battery voltage. For a 12 V battery, we recommend panels with a minimum number of 32 cells and a maximum number of 108 cells (panels in series). It is therefore possible to charge a 12 V battery and panels with an operating voltage of 24 V. For 24 V systems, we recommend panels with a minimum number of 72 cells and a maximum number of 108 cells. The purpose is to achieve sufficient voltage for efficient and full charging of the battery.
The solar controller has a DC output for powering a DC load. The DC output voltage is equal to the battery voltage. So if you have, for example, a 12 V battery - we can power a 12 V load on the DC output.
BatteryLife algorithm - adaptive charging to extend battery life. The controller constantly monitors the battery charge level and gradually increases the voltage level at which the load is disconnected day by day until the absorption voltage is reached (the battery is fully charged). This is followed by a decrease in the voltage level at which the load is disconnected. In this way, the battery can be fully charged approximately once a week even with reduced solar gains and higher load, which will have a positive effect on the battery life. This is an optional function.
Warning: Victron Energy MPPT controllers are not permitted to be used in combination with photovoltaic panel optimizers. When used, damage to both MPPT controllers and optimizers may occur and this damage may not be recognized as a valid complaint.
