Performance highlights at a glance:
-
MPPT solar charge controller: As a highly developed MPPT (Maximum Power Point Tracking) charge controller, the device continuously finds the point of maximum power for your solar modules. This increases energy yield by up to 30% compared to conventional PWM controllers, especially in cool weather conditions and when there is a large difference between PV and battery voltage.
-
Maximum PV voltage: 250 V (absolute upper limit under the coldest conditions; start and operating maximum: 245 V). This allows many solar modules to be connected in series, resulting in thinner cables, lower costs, and minimal power losses—ideal for large installations.
-
Maximum charging current: 100 A. This means that even large battery storage systems are charged quickly and powerfully to maximize your energy availability.
-
Flexible system voltage: Automatic detection for 12 V, 24 V, and 48 V systems; 36 V can be configured manually. This adaptability ensures compatibility with almost any common battery configuration.
-
Maximum efficiency: Up to 99%. With almost no energy lost during conversion, you get the absolute maximum out of your solar system.
After a busy morning in the workshop, with the circular saw and welding machine running, you can see how the 100 amp charging current quickly recharges your batteries. This gives you the assurance that you will have more than enough energy available for the evening and the next day.
More than just charging: Intelligent functions for control and efficiency
-
Ultra-fast MPPT tracking: Its extremely fast response to changing light conditions, such as passing clouds, minimizes energy losses and can increase yield by up to 10% compared to slower algorithms.
-
Advanced partial shading detection: The innovative algorithm scans the entire voltage curve to always find the global maximum power point (Global MPP), even when shaded by trees or buildings, instead of remaining at a weaker local maximum.

VE.Can & VE.Smart Network for synchronized parallel operation: Up to 25 controllers can be networked via the robust VE.Can interface. In addition, the VE.Smart Network enables wireless synchronization of up to 10 devices via Bluetooth, which greatly simplifies installation in smaller multi-controller systems.
-
Programmable relay: The integrated, potential-free relay can be used for a variety of control tasks, such as starting a generator when the battery is low or switching on an alarm siren.
-
Adaptive charging algorithm: The intelligent, multi-stage charging algorithm dynamically adjusts the duration of the charging phases to the discharge state of the battery. This ensures gentle charging and maximizes the service life of your batteries.
-
Sophisticated fanless design: The robust design with a solid aluminum heat sink dissipates heat through natural convection. This design philosophy prioritizes absolute silence and maximum reliability (no failure-prone moving parts) over maximum performance in extremely hot environments, where derating may occur for self-protection.
-
Battery rescue function: The controller can revive even deeply discharged lead-acid batteries (down to 0 V) and connect to lithium batteries whose internal BMS (Battery Management System) has disconnected the connection.
Clouds roll in during the afternoon. A quick glance at the VictronConnect app shows you that the controller still ensures a constant yield thanks to its intelligent algorithms. With this information, you can confidently decide to run the water pump for the garden or the washing machine.
The decisive advantage: Strategic strengths for future-proof solar systems
-
Maximum energy yield under all conditions: The perfect combination of ultra-fast tracking and intelligent partial shading detection ensures that you always harvest the maximum amount of energy possible under real, often imperfect conditions.
-
Unmatched scalability and system integration: The unique combination of Bluetooth, VE.Direct, and VE.Can gives this controller outstanding flexibility. Your system grows with your needs—from a single application to a huge array, seamlessly integrated into the Victron GX and VRM ecosystem for global control.
-
Professional robustness and control: The fanless design, combined with comprehensive electronic protection mechanisms and extensive configuration options, ensures reliability and controllability at the highest professional level.
Your energy needs grow as you also equip the roof of your new garage with solar panels. Instead of a complete system conversion, you simply integrate a second SmartSolar controller via VE.Can. Both work together perfectly in sync right away—an investment that adapts to your life, not the other way around.

Perfect additions: Recommended accessories for system optimization
-
Smart Battery Sense / BMV-712 / SmartShunt: These external sensors are essential for maximum precision. Mounted directly on the battery terminals, they measure the exact voltage and temperature and send this data wirelessly to the charge controller. The controller compensates for voltage losses in the cables and adjusts the charging curve perfectly to the battery temperature. The result: even more efficient charging and a significantly longer service life for your valuable batteries.
-
Optional LCD display: For users who prefer constant monitoring directly on the device without a smartphone, a plug-in display is available. It simply plugs into the front of the controller and displays all important operating data at a glance, making on-site monitoring easier.
From practice: Frequently asked questions (FAQ) from the Victron community
Based on the experiences of users and installers, we have compiled solutions for typical practical situations here:
-
My charge controller displays "Charger off - Disabled by remote control or BMS." What can I do? This is a typical problem during initial commissioning. The cause is usually a missing jumper on the remote on/off connection. Ensure that terminals 'L' and 'H' are connected to the jumper so that the controller can enable the charging process.
-
The PV voltage immediately drops to 0 V when I connect the modules. Is the controller defective? In newer models (especially devices with a serial number starting with HQ2150), this probably indicates that an internal protection relay has been triggered. This relay can be reset using a special procedure in the VictronConnect software. In older models, this symptom may indicate a hardware defect.
-
I have two identical controllers running in parallel, but one delivers much less power. Why is this? There are several possible reasons for this behavior. An MPPT controller works most efficiently close to its rated power; an underloaded controller has a lower efficiency. Also check for minimal differences in the shading of the two PV arrays or deviations in the cabling. Swapping the PV inputs between the controllers helps to isolate the source of the error.

Safe operation right from the start: Installation and planning instructions
The following installation guidelines are crucial for the safe and long-lasting performance of your system:
-
Location and ventilation: Always mount the device vertically in a dry, protected, and well-ventilated location. Ensure there is sufficient free space (at least 10 cm) around the device so that air can circulate freely and passive cooling can function optimally.
-
Design of the PV generator: Observe three golden rules: The open-circuit voltage (Voc) of the modules must never exceed the absolute upper limit of 250 V, even at the coldest temperatures (start and operating maximum 245 V). The short-circuit current (Isc) of the entire array must not exceed 70 A. The PV voltage must be at least 5 V above the battery voltage to start the charging process. Oversizing the PV power ("over-paneling") is permitted and often useful to maximize yield in low light conditions; the controller automatically limits the power for self-protection.
-
Cabling and fusing: Use cables with a sufficient cross-section (up to 35 mm²) to minimize losses and ensure a safe connection. Install suitable DC fuses or circuit breakers on both the PV side and the battery side in accordance with the applicable standards.
