Victron SmartSolar MPPT 150/35 - 150V - 35A - UL Approved

The Victron SmartSolar MPPT 150/35 - 150V - 35A is a UL-approved maximum power point tracking (MPPT) solar charge controller designed for off-grid and grid-tied renewable energy systems. This controller bridges solar panel arrays and battery banks, intelligently converting and regulating solar energy to optimize charge rates and system efficiency. Users seeking to maximize energy harvest from rooftop, ground-mounted, or portable solar installations—from RVs and boats to remote cabins and emergency backup systems—rely on this compact yet powerful solution to reduce charging times and extend battery lifespan.

SmartSolar technology employs state-of-the-art MPPT algorithms that continuously scan solar panel output and adjust load resistance to extract maximum available power under all lighting and temperature conditions. The unit handles up to 150 volts input and delivers 35 amps of charging current, making it suitable for 12V, 24V, or 48V battery banks. Housed in a compact 6 x 4 x 9-inch enclosure weighing just 1.5 lbs, the controller features integrated Bluetooth connectivity for remote monitoring via the Victron Connect mobile app, allowing users to track real-time charge rates, battery voltage, and system diagnostics without physical access to the hardware. Its rugged aluminum construction and UL approval ensure reliability in demanding environments.

This controller excels in applications where high solar input voltage and moderate current requirements align—particularly in systems using long cable runs or multiple panel strings where voltage drop is a concern. Installers and system integrators value its compatibility with industry-standard battery types, including lithium iron phosphate (LiFePO₄), lead-acid, and gel batteries, thanks to configurable charge algorithms. Whether upgrading an existing solar setup or building a new renewable energy system from scratch, the Victron SmartSolar MPPT 150/35 delivers the efficiency, monitoring capability, and durability expected from a premium charge controller for demanding off-grid and hybrid applications.
