Victron SmartSolar MPPT 250/70-Tr: 70A Ultra-High Voltage Solar Controller (SCC125070221)

The Victron Energy SmartSolar MPPT 250/70-Tr (SCC125070221) is a high-power, high-voltage charge controller designed for professional off-grid and grid-hybrid solar systems. With a 250V maximum PV input and 70A continuous charge current, it supports large solar arrays while minimizing wiring complexity and balance-of-system costs. Featuring integrated Bluetooth Smart, you can wirelessly manage and monitor your system harvest via the VictronConnect app.

Maximum Harvest & Intelligent Tracking

• Bluetooth Smart Integrated: No dongle required. Monitor real-time watts, battery voltage, and 30-day historical data directly from your smartphone.
• Ultra-Fast MPPT Tracking: Improves energy harvest by up to 30% compared to PWM controllers and up to 10% compared to slower MPPT units, especially during overcast days.
• High Voltage Capacity (250V): Allows for long series strings of solar modules, significantly reducing DC cable losses and installation time.
• Advanced Shading Detection: Innovative algorithm ensures the controller locks onto the absolute best Power Point, preventing energy loss during partial shading.
• Tr Version (Screw Terminals): Equipped with heavy-duty screw terminals for secure, high-current connection of cables up to 35 mm² (AWG2).
