Efficient and intelligent solar charge controller for 12V, 24V, 36V, and 48V battery systems.
The Victron SmartSolar MPPT 150/45 is an advanced MPPT solar charge controller that maximizes energy from your solar panels and charges the battery bank quickly and safely. It can handle up to 150 V solar panel voltage and 45 A charging current, making it suitable for boats, motorhomes, and off-grid energy systems.
The controller uses Victron's ultra-fast MPPT technology, which constantly finds the optimal operating point for the solar panels and ensures maximum energy production – even with changing light conditions or partial shading.
It also has built-in Bluetooth, so you can monitor and configure the system directly via the VictronConnect app on your smartphone.

User manual
💡 Tip from SejlStrøm:
This model is perfect for smaller and medium-sized boat solar systems, where you typically have 200-600 W solar panels and a battery bank of 100-400 Ah. MPPT technology typically provides 10-30% more energy than traditional PWM charge controllers.
