Victron SmartSolar MPPT 150/45 Solar Charge Controller – 45A, 150V
The Victron SmartSolar MPPT 150/45 is a high-performance 45A solar charge controller designed to maximise energy harvest from your PV array and protect your battery bank for the long term.
Using ultra-fast MPPT tracking and intelligent multi-stage charging, it delivers more usable power than conventional PWM regulators, even in cloudy or partially shaded conditions.
Key Features
- Ultra-fast MPPT tracking to increase usable solar yield and reduce charging time compared to PWM controllers.
- Advanced maximum power point detection maintains high performance in partial shading and changing weather conditions.
- Automatic 12V, 24V and 48V battery voltage selection (36V configurable via software) for flexible system design in homes, vehicles and off‑grid systems.
- Rated charging current of 45A with nominal PV power up to 650W (12V), 1300W (24V), 1950W (36V) and 2600W (48V), ideal for medium-sized solar installations.
- Maximum PV open circuit voltage of 150V and PV short-circuit current up to 50A, supporting higher-voltage string configurations to reduce cable losses.
- Integrated Bluetooth connectivity for real-time monitoring and configuration using the VictronConnect app on your smartphone or tablet.
- Multi-stage adaptive charging with configurable algorithms to optimise battery health and extend service life for lead-acid and lithium batteries.
- High peak efficiency of up to 98% for minimal energy loss and cooler, more reliable operation.
- Built-in electronic protections including PV reverse polarity, output short circuit and over-temperature with automatic power derating at high temperatures.
- Compact, robust enclosure with IP43 protection for electronics, suitable for indoor or protected installations in homes, workshops and vehicles.
Why Buy This Controller
- Designed by a leading solar electronics manufacturer, this controller offers proven reliability and a long service life, giving homeowners and professionals confidence in critical off‑grid and backup systems.
- Higher charging efficiency and smarter battery management help reduce generator run time, cut energy costs and improve overall system performance.
- Easy commissioning and monitoring via Bluetooth reduce installation time and call-outs, making it an excellent choice for trade installers and integrators.
- Flexible system compatibility with 12V–48V battery banks and wide PV input limits makes it suitable for upgrades, expansions and mixed-technology systems.
- Comprehensive protection features and intelligent charging help safeguard expensive battery banks, supporting long-term return on investment.
Suitable For
- Residential off-grid solar systems and battery-backed backup power for homes, cabins and holiday properties.
- Campervans, motorhomes, caravans and marine applications where space is limited but performance and monitoring are critical.
- Small to medium commercial and light industrial solar battery systems requiring efficient DC charging and robust control.
- Agricultural and remote site power, including pumps, lighting, security systems and telecoms equipment.
- System upgrades from PWM regulators to MPPT technology to increase harvested energy without replacing existing PV modules.
