Description
The Victron SmartSolar MPPT 150 | 60 is a robust, high-efficiency MPPT charge controller for medium to large off-grid systems. With 150V PV open-circuit voltage support and 60A charging output, it’s ideal for RV solar installations, off-grid cabins, marine systems, van conversions, tiny homes, and mobile work trailers.
The controller uses Victron’s Ultra-Fast Maximum Power Point Tracking, continuously optimizing panel output—even during shading, low sunlight, or cloudy conditions. Integrated Bluetooth Smart enables complete system configuration and monitoring using the VictronConnect app, while the VE.Direct port allows communication with a Cerbo GX or other Victron ecosystem components.

Solar Array Capability
The MPPT 150 | 60 supports solar strings up to 150V Voc, allowing long cable distances and compatibility with a wide range of panel types including high-voltage residential modules and multiple RV-style panels in series.
Maximum Recommended Solar Array Size
| Battery Voltage | Max Charge Amps | Max Recommended Solar |
|---|---|---|
| 12V system | 60A | ≈ 900W |
| 24V system | 60A | ≈ 1,800W |
| 48V system | 60A | ≈ 3,500W |
The controller safely limits output to 60A, so slight array oversizing is acceptable.
