MPPT Solar Charge Controller Victron Energy SmartSolar 150/45

Product detailed description

Robust and fast MPPT controller for demanding conditions with panel voltage up to 150V, maximum charging current 45 A. Battery 12/24/48V, PV max 650/1300/2600Wp. Full 5-year warranty. Integrated bluetooth.
Victron Energy MPPT solar charge controllers are among the absolute world leaders in this field. It offers ultra-fast MPPT tracking, which ensures the maximum possible solar gains. Especially under overcast skies with frequent changes in light intensity, 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 650 Wp for 12 V systems, 1300 Wp for 24 V systems and 2600 Wp for 48 V systems. If these values are exceeded, the controller will not be damaged, but will automatically reduce the incoming power from the panels to acceptable values. The solar controller is factory preset for eight battery types - the appropriate type is selected using a rotary switch located on the body of the controller.
The maximum open-circuit voltage (referred to as Voc) of connected solar panels must not exceed 150V (note: as the outside temperature drops, the voltage of solar panels rises). The maximum input short-circuit current of PV panels must not exceed 50A, otherwise permanent damage may occur.
The new range of SmartSolar MPPT controllers offers built-in Bluetooth
This new feature brings the possibility of connecting your "smart" phone/tablet with your "smart" solar controller.
You can monitor many system parameters and historical statistics for the last 30 days. You also have the option to adjust operating parameters.
The VictronConnect app can also be downloaded for free on Google Play or the App Store.
If you want to do the above using a PC, you have the option of using a VE.direct to USB cable to connect the controller and the PC. You just install the Victron Connect program on your computer.
The internal electronic components are protected with a resin coating against adverse effects and for long service life. It thus offers increased resistance with IP43 protection for electronic components and IP22 for connectors. Designed for vertical position on a non-flammable surface, with cabling connected from below.
The controller contains an internal temperature sensor for appropriate adjustment of the charging voltage. Automatic detection of system voltage 12/24/48 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 for quick recharging of a discharged battery. This phase is followed by constant voltage with decreasing current for full charging of the battery without dangerous overcharging that reduces battery life. A charged battery is kept in a charged state with a very low current and low voltage. If the voltage on the battery drops below 13.2 V, for example due to load, a new charging cycle starts.
The voltage from the panels must exceed the battery voltage by 5 V for the controller to start working and charging the battery. The controller charges until the voltage from the panels is 1 V higher than the battery voltage. For 12 V batteries, we recommend panels with a minimum of 32 cells and a maximum of 108 cells (panels in series). It is thus possible to charge a 12 V battery even with panels with a working voltage of 24 V. For 24 V systems, we recommend panels with a minimum of 72 cells and a maximum of 108 cells. The purpose is to achieve sufficient voltage for efficient and full charging of the battery.
This more powerful range of solar controllers is not equipped with a DC output. To connect a DC load to the battery, we recommend using the "BP Battery Protect" with a maximum load current of up to 220A.
