Victron Energy SmartSolar MPPT Solar Charge Controller 35A 150V Input, Bluetooth monitoring for 12/24/36/48V systems

This compact MPPT (Maximum Power Point Tracking) controller from Victron Energy converts sunlight into usable power while intelligently managing charging stages to extend battery life. Built for off-grid and hybrid systems, it supports up to 150V PV input and delivers 35A continuous charging. With Bluetooth connectivity through VictronConnect, you can monitor performance, adjust charge profiles, and update firmware from a smartphone.

How does this controller improve solar harvest on partly shaded roofs?

The SmartSolar MPPT uses rapid maximum power point tracking and adaptive algorithms to find the best operating point for your panels, even when shading or variable cloud cover reduces output. It reacts quickly to changing conditions so energy losses are minimized.

• Fast MPP tracking reduces time spent away from peak power.
• Intelligent algorithms optimize voltage/current for mixed-irradiance strings.
• Accepts PV input up to 150V for larger panel arrays or higher string voltages.

Can I use multiple units together and how do they coordinate?

Yes—multiple SmartSolar MPPT units can synchronize to act as a single charging system. They switch charging stages in unison to ensure balanced, efficient charging and to avoid competing control behaviors that can stress batteries.

• Synchronized charging stages for consistent battery management.
• Simple network setup via Victron’s communication interfaces and app.
• Scales system capacity by adding units without sacrificing control quality.

What monitoring and configuration options are available?

Bluetooth access through VictronConnect provides live data, 30-day performance history, and full configuration of battery presets, alarms, and firmware updates. Local display options and third-party integration are supported for more advanced system telemetry and logging.

• Real-time readouts of PV volts, charge amps, and battery status.
• 30-day performance history viewable in the app for trend analysis.
• Firmware updates and custom charge settings via VictronConnect.

How does the load output protect my battery and appliances?

The controller includes an intelligent load output that you can set to disconnect at a chosen voltage threshold to prevent deep discharge. That same output can directly power DC loads and is managed automatically by the MPPT to protect battery health.

• User-defined low-voltage disconnect to avoid battery damage.
• Automatic reconnection logic when battery voltage recovers.
• Safe powering of DC loads with monitored cut-off and restart behavior.

Who is this for: The Victron Energy SmartSolar MPPT 150V 35A suits homeowners, RV and boat owners, cabin operators, and small commercial installations that need a reliable, configurable charge controller. Choose this unit if you run multiple panel strings, want Bluetooth system control, or plan to scale with synchronized controllers for higher charging capacity. It’s an excellent option when you require robust MPPT performance, protective load management, and straightforward mobile monitoring without complex setup.
