Victron Energy SmartSolar MPPT Solar Charge Controller 75V 10A 12/24V — Fast MPPT, Bluetooth monitoring

The Victron Energy SmartSolar MPPT 75V 10A is a compact, high-efficiency solar charge controller that optimizes panel output and maintains battery health for 12V or 24V systems.

Designed for small off-grid systems, cabins, vehicles and auxiliary power setups, this SmartSolar MPPT uses fast maximum power point tracking and adaptive charging algorithms to extract the most energy from your solar array. It supports synchronized operation with other controllers, configurable load output and wireless monitoring via the VictronConnect app, making it a versatile choice for hobbyists and professionals who need precise, reliable battery management.

How does this controller increase solar energy harvest?

The SmartSolar MPPT continuously searches for the optimal operating point of your solar panels so they deliver maximum power under changing light and temperature conditions. Its rapid MPPT algorithm reacts quickly to shade, clouds and panel mismatch, improving energy capture compared with simple charge controllers.

• Fast maximum power point tracking for improved yield.
• Operates with panel input up to 75V for flexible array designs.
• Works efficiently with partially shaded or mixed-module arrays.

What charging features protect and extend my battery life?

Multiple charging stages and smart battery presets let you tailor the charge profile to common battery chemistries, reducing stress and prolonging service life. Synchronized charging across multiple SmartSolar units ensures all controllers follow the same charge cycle for balanced system performance.

• Built-in multi-stage charging with configurable presets.
• Synchronized charge staging for multiple controllers in one system.
• Automatic load disconnect to prevent deep battery discharge.

How can I monitor and configure the controller remotely?

The VictronConnect app connects wirelessly to the controller for real-time telemetry, historical performance data and firmware updates. Use the app to set battery type, change voltage thresholds, review 30-day performance logs, and receive alerts to stay informed about system status.

• Wireless VictronConnect support for configuration and status viewing.
• 30-day performance history and real-time data display.
• Firmware updates and alarm settings via the app.

Can I power devices directly from the controller’s load output?

Yes—this SmartSolar includes an intelligent load output that can switch loads off at a configurable voltage to protect the battery. That feature makes it suitable for lighting, pumps or other DC loads that should be protected from battery over-discharge without extra relays.

• Configurable disconnect voltage to protect battery reserve.
• Secure direct powering of DC loads from the controller.
• Automatic reconnection when battery voltage recovers.

Who is this for? Installers, RV and boat owners, tiny-home builders, and off-grid hobbyists who need a small-footprint MPPT controller with strong monitoring and synchronization capabilities will find this SmartSolar model well suited to 12V and 24V battery systems. Its balance of advanced MPPT performance, app connectivity, and intelligent load control makes it ideal for anyone who wants efficient energy harvest, battery protection, and straightforward system management without adding unnecessary complexity.
