Model SCC125110441 | 75V Max PV | 10A Charge Current | 12/24V Auto | Built-In Bluetooth | 98% Efficiency | 5-Year Warranty
The Victron Energy SmartSolar MPPT 75/10 (model SCC125110441) is a compact, high-efficiency solar charge controller engineered to extract maximum power from PV arrays of up to 75V open-circuit voltage while delivering up to 10A of regulated charge current to 12V or 24V battery banks with automatic voltage detection. Operating at up to 98% conversion efficiency with ultra-fast Maximum Power Point Tracking that responds dynamically to changing irradiance and temperature conditions, the SmartSolar 75/10 integrates built-in Bluetooth for wireless monitoring and configuration via the VictronConnect app, remote firmware updating via the VRM portal, and Victron's proprietary BatteryLife algorithm for intelligent load management and extended battery longevity — all in a 0.5 kg, 100 × 113 × 40 mm enclosure rated for operation from –30°C to +60°C and backed by a 5-year product warranty.
Ultra-Fast Maximum Power Point Tracking (MPPT): The SmartSolar 75/10 employs Victron's ultra-fast MPPT algorithm, which continuously tracks and locks onto the PV array's maximum power point — dynamically adjusting the electrical operating point in response to rapid changes in solar irradiance, cloud cover, temperature, and shading — ensuring the connected battery receives the highest possible charge current at all times and delivering meaningfully more energy per day compared to PWM controllers, particularly in partially shaded or variable-irradiance conditions.
Built-In Bluetooth & VictronConnect App Integration: Integrated Bluetooth connectivity allows users to wirelessly monitor real-time PV power, battery voltage, charge current, state of charge, historical yield data, and controller status directly from the free VictronConnect app on iOS or Android — and to configure charging parameters, battery type, absorption voltage, float voltage, and load output behavior without any physical wiring or additional hardware, making commissioning and ongoing system management straightforward for both installers and end users.
Automatic 12/24V Battery Voltage Detection: On first connection, the SmartSolar 75/10 automatically detects whether a 12V or 24V battery bank is connected and configures its charging algorithm accordingly — eliminating the risk of incorrect voltage selection during installation, reducing setup time, and ensuring the controller immediately operates with the correct absorption, float, and equalization voltage thresholds for the detected battery system without requiring manual intervention.
BatteryLife Algorithm & Load Disconnect Protection: The BatteryLife algorithm — available on models equipped with a load output — intelligently manages connected DC loads by monitoring daily solar harvest and battery state of charge, dynamically adjusting the load disconnect threshold to ensure the battery always receives sufficient recharge energy to sustain multi-day operation in low-irradiance conditions, actively preventing the deep discharge cycles that accelerate battery degradation and significantly extending the service life of lead-acid and lithium battery banks.
Remote Firmware Updates via VRM Portal: When connected to the Victron VRM online monitoring portal via a compatible Victron GX device or Bluetooth gateway, the SmartSolar 75/10 supports over-the-air firmware updates — allowing Victron to deliver new features, algorithm improvements, additional battery profiles, and compatibility updates to deployed units remotely without requiring a site visit, physical connection, or manual firmware file transfer, ensuring the controller remains current throughout its operational life.
The SmartSolar MPPT 75/10 accepts DC input from a connected PV array at up to 75V open-circuit voltage and steps it down through its high-frequency MPPT converter to the precise charging voltage required by the connected 12V or 24V battery bank — operating at up to 98% conversion efficiency to minimize energy loss and heat generation. The controller continuously sweeps the PV array's I-V curve to locate and track the maximum power point, delivers a three-stage bulk/absorption/float charge profile optimized for the connected battery chemistry, monitors load output behavior via the BatteryLife algorithm, and simultaneously broadcasts all operating parameters over Bluetooth to any paired VictronConnect device for real-time monitoring and remote configuration.
MPPT Tracking & Power Conversion: The controller's MPPT algorithm operates by rapidly sampling the PV array's output voltage and current at multiple operating points, constructing a real-time power curve, and commanding the internal DC-DC converter to hold the array at its peak power output — a process that repeats continuously throughout the day, ensuring the battery receives maximum available charge current even as the sun angle, temperature, and shading conditions shift, with Victron's ultra-fast tracking algorithm responding to transient irradiance changes in milliseconds to capture energy that slower controllers would miss.
Bluetooth Monitoring & VictronConnect Interface: The onboard Bluetooth radio continuously broadcasts operating data — PV voltage, PV current, PV power, battery voltage, charge current, charge state, daily yield, historical yield, and active alarms — to any paired smartphone or tablet running VictronConnect within approximately 10 metres, enabling installers to commission the system, verify charging behavior, adjust parameters, and diagnose faults entirely wirelessly from ground level without accessing the controller directly, and allowing system owners to monitor their solar yield and battery status from the convenience of their mobile device.
Adaptive Load Management & BatteryLife: When load output is active, the SmartSolar's adaptive load management system tracks the battery's daily recharge history and state of charge over time — raising the load disconnect threshold during periods of poor solar harvest to ensure the battery receives a full recharge cycle before loads are reconnected, and lowering it during periods of sustained good harvest to maximize the load's daily operating hours — creating a self-calibrating protection system that balances load availability with battery health automatically across seasonal solar variation without requiring user intervention.
