MPPT Solar Charge Controller Victron Energy SmartSolar 100/20

Product detailed description

Robust and fast MPPT controller for demanding conditions with panel voltage up to 100V, maximum charging current 20 A. Battery 12/24V/48, PV max 290/580/1160Wp. Full 5-year warranty. Integrated Bluetooth.
As proof of high quality, Victron Energy provides an extended full 5-year warranty on all MPPT controllers.
Victron Energy MPPT solar controllers are among the absolute world leaders in this field. They offer ultra-fast MPPT tracking, ensuring the maximum possible solar yield. Especially under cloudy skies with frequent changes in light intensity, solar yields are 30% higher compared to classic PWM controllers, or 10% higher compared to slower MPPT controllers.
The maximum solar panel power is 290 Wp for 12 V systems, 580 Wp for 24 V systems, and 1160 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 and it is usually not necessary to make major adjustments to the settings.
The maximum open-circuit voltage (referred to as Voc) of the connected solar panels must not exceed 100V (note: solar panel voltage increases as the outdoor temperature decreases). The maximum input short-circuit current of the PV panels must not exceed 20A, 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.
You can also download the VictronConnect app for free on Google Play or the App Store.
If you want to do the above using a PC, you can use a VE.direct to USB cable to connect the controller and the PC.
The internal electronic components are protected with a resin coating against adverse effects and for a long service life. This offers increased protection rating of IP43 for electronic components and IP22 for connection connectors. Designed for vertical mounting on a non-flammable surface, with cabling connected from below.
The controller contains an internal temperature sensor for corresponding adjustment of the charging voltage.
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 a 12 V battery, we recommend panels with a minimum of 32 cells and a maximum of 108 cells (panels in series). It is therefore possible to charge a 12 V battery with panels with an operating 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 battery charging.
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 12V battery, the DC output can power a 12V load. The maximum DC output current is 20A for a 12V battery, 20A for a 24V battery, and 1A for a 48V battery.
BatteryLife algorithm - adaptive charging to extend battery life. The controller continuously monitors the state of charge of the battery and gradually increases the voltage level at which the load is disconnected day by day, until the absorption voltage is reached (battery fully charged). This is followed again by a decrease in the voltage level at which the load is disconnected. In this way, a full battery recharge can occur approximately once a week even with reduced solar yields and higher load, which has a positive effect on battery life. This is an optional feature.
