Victron SmartSolar MPPT 150/35 Solar Charge Controller

High-Performance Solar Tracking for Serious Off-Grid Systems

The Victron SmartSolar MPPT 150/35 is a robust solar charge controller built for larger, more demanding energy systems. Unlike smaller controllers, this unit handles a PV input voltage of up to 150V, allowing you to string more solar panels in series for easier installation and better low-light performance.

Whether you are running a 12V camper setup or a 48V off-grid cabin, this controller automatically maximizes your energy harvest.

Why Choose the SmartSolar 150/35?

• Ultra-Fast MPPT Tracking: In cloudy weather where light intensity changes constantly, this controller adapts instantly. It improves energy harvest by up to 30% compared to PWM charge controllers and up to 10% compared to slower MPPT controllers.

• 12V to 48V Versatility: This unit is future-proof. It automatically detects 12V, 24V, or 48V battery systems (and supports 36V via software), making it perfect for scaling up your power bank later.

• Built-in Bluetooth (Smart): Monitor your solar yield, battery voltage, and current in real-time on your smartphone via the VictronConnect App. You can also configure settings wirelessly without needing to access the physical unit.

• Rescue Your Batteries: Have a battery that has been discharged to 0V? The SmartSolar 150/35 will attempt to revive it using a low-current pulse recharge, reconnecting fully once the voltage rises.
