Victron SmartSolar MPPT 100/15 & 100/20 — high-efficiency solar charge controllers for 12V and 24V off-grid systems

The Victron SmartSolar MPPT 100/15 and 100/20 charge controllers deliver advanced MPPT efficiency in compact sizes ideal for 4WD touring, caravans, van builds, camper trailers and small off-grid solar systems. Designed to harvest more power in low-light and shaded conditions, these models optimise panel performance automatically while providing full wireless monitoring via Bluetooth.

Choose your model

• SmartSolar MPPT 100/15 (15A): Suitable for smaller systems up to approx. 220W at 12V, perfect for canopy setups, compact campers and fridge-plus-accessories builds

• SmartSolar MPPT 100/20 (20A): Ideal for medium systems up to approx. 290W at 12V, supporting fridges, lighting, pumps, charging electronics and lithium battery banks
  Both models support automatic 12V/24V system detection and work with parallel or series solar array configurations up to 100V open circuit.

Built-in Bluetooth for real-time solar management
Bluetooth Smart allows configuration and monitoring directly from the VictronConnect app. View live charging data, battery history, solar harvest logs and update firmware wirelessly, without external dongles or accessories.

VE.Direct for wired monitoring and system expansion
For integrated systems, VE.Direct provides a stable connection to Cerbo GX, GX Touch, PC interfaces and other Victron monitoring equipment. Ideal for van builds, caravans and marine installations requiring central control.

Ultra-fast Maximum Power Point Tracking (MPPT)
Victron’s MPPT algorithm constantly adjusts to changing sunlight to maintain the most efficient voltage point. Compared to PWM and slower MPPT controllers, this improves real-world output in shade, cloud cover, early mornings and late afternoons.

Intelligent adaptive charging
Automatic 3-stage charging (Bulk, Absorption, Float) protects and maintains battery health for AGM, GEL, Flooded and LiFePO₄ batteries with internal BMS. Programmable charge profiles allow further tuning through the VictronConnect app.

Durable, fanless design
With a conversion efficiency exceeding 98%, these controllers deliver full output up to 40°C ambient temperature without fan cooling. Protective features include:

• Reverse polarity protection

• Over-temperature power derating

• Short circuit and over-voltage protection

• Battery temperature compensation for accurate charging in all climates

Ideal for

• 4WD dual battery setups and canopy systems

• Caravans and camper trailers

• Small marine house banks

• Tiny homes, sheds and remote power systems
