Victron SmartSolar MPPT 150/45 Solar Charge Controller
12/24/48V Auto-Select | 45A Rated Charge | Ultra-Fast MPPT Technology
The Victron SmartSolar MPPT 150/45 Solar Charge Controller is engineered to maximise energy harvest from your solar panels and efficiently store it in your battery bank. Utilising advanced Maximum Power Point Tracking (MPPT) technology, this controller intelligently optimises power delivery to achieve a full charge in the shortest possible time, thereby extending battery life and ensuring system reliability.
Designed for 12V, 24V, and 48V battery systems, the SmartSolar MPPT 150/45 automatically detects the system voltage and delivers a robust 45A rated charge current. Its capability to recharge severely depleted batteries, even those at 0 Volts (provided they are not permanently damaged), makes it a highly versatile and resilient solution for various solar installations.
OPTIMISED HARVEST: Ultra-fast MPPT improves energy harvest by up to 30% compared to PWM controllers.

Common Questions
What battery voltages does this controller support?
The Victron SmartSolar MPPT 150/45 automatically supports 12V, 24V, and 48V battery systems. A 36V system can also be configured manually using the VictronConnect software.
Can I monitor the controller remotely?
Yes, the controller features built-in Bluetooth Smart for wireless monitoring and configuration via the free VictronConnect app on your smartphone or tablet. It also has a VE.Direct port for wired connections to other Victron GX devices or a PC.
Is this charge controller suitable for partially shaded solar panels?
Absolutely. The SmartSolar MPPT 150/45 features an advanced Maximum Power Point Detection algorithm that optimises energy harvest even when partial shading creates multiple power peaks on the PV curve.
What is the maximum PV voltage it can handle?
The controller has an absolute maximum PV open circuit voltage of 150V. For safe start-up and continuous operation, the maximum PV open circuit voltage should not exceed 145V.
Installation Notes
- Professional installation by a qualified electrician or solar installer is highly recommended to ensure safety and optimal performance.
- Ensure correct wiring polarity for both PV array and battery connections to prevent damage to the controller and system components.
- Mount the controller in a well-ventilated area, away from direct sunlight and sources of heat, to allow for efficient passive cooling.
- Always refer to the comprehensive Victron Energy SmartSolar MPPT 150/45 manual for detailed installation instructions and safety guidelines.
Before You Buy
- Verify your battery bank voltage (12V, 24V, or 48V) to ensure compatibility with this auto-selecting controller.
- Confirm your total PV array open circuit voltage (Voc) and short circuit current (Isc) are within the controller's maximum limits (145V operating max Voc, 50A max Isc).
- Consider your total PV power output to ensure it aligns with the controller's nominal PV power ratings for your chosen battery voltage.
- Assess your system's future expansion needs, as the 150/45 model offers significant capacity for growth.
