DESCRIPTION
Victron SmartSolar MPPT 250/70-MC4 VE.Can Bluetooth Solar Charge Controller
High-Performance MPPT Solar Charge Controller for 12V, 24V, and 48V Systems
The Victron SmartSolar MPPT 70A charge controller brings advanced Maximum Power Point Tracking (MPPT) technology to your off-grid, mobile, or backup power system. Designed to extract the maximum possible energy from your solar array, this controller uses ultra-fast MPPT tracking to adapt to changing light conditions—delivering up to 30% more energy than traditional PWM controllers and up to 10% more than slower MPPT units, especially under cloudy or partially shaded skies.
With a peak conversion efficiency of 99% and full rated output up to 40°C, this controller operates without a cooling fan, ensuring silent, reliable performance. The built-in Bluetooth Smart interface allows wireless setup, monitoring, and firmware updates via the free VictronConnect app, while the VE.Can port enables wired integration with GX devices and parallel synchronisation of multiple controllers for larger systems.
Ultra-Fast MPPT and Advanced Shading Response
In real-world conditions, clouds and partial shading can cause conventional MPPT controllers to lock onto a local power peak, missing the true maximum power point. The Victron SmartSolar algorithm continuously scans the full power-voltage curve to lock onto the optimal MPP, maximising energy harvest even when shadows fall across part of your array. This is especially valuable for installations on vehicles, boats, or rooftops where shading is unavoidable.
Flexible Charging for Any Battery Chemistry
The controller supports 12V, 24V, and 48V battery banks with automatic voltage detection (36V manual), and includes eight pre-programmed charge algorithms for lead-acid, AGM, gel, and lithium batteries. A fully user-definable charge profile is also available, giving you complete control over absorption, float, and equalisation voltages. Temperature compensation is built in, and optional external voltage and temperature sensing via a Smart Battery Sense or BMV-712 Smart Battery Monitor ensures precise charging even when the controller is mounted away from the battery.
Robust Protection and Reliable Operation
Engineered for demanding environments, the SmartSolar MPPT includes comprehensive electronic protection: PV reverse polarity, PV short circuit, over-temperature, and PV reverse current protection. The electronics are rated IP43, while the connection area is IP22, making it suitable for indoor, unconditioned spaces. With an operating range of -30°C to +60°C and an altitude rating of up to 5000 m, this controller is built to perform in Australia’s harshest climates.

Seamless System Integration
The SmartSolar MPPT is designed to work as part of a complete Victron energy system. Connect it to a Color Control GX or other GX device via VE.Can for centralised monitoring and control, or use Bluetooth to synchronise up to 10 controllers in parallel. For larger arrays, VE.Can allows up to 25 units to operate in synchronised parallel mode, sharing charge current evenly across multiple controllers.
The programmable relay can be configured to trigger on low battery voltage, high temperature, or other events, while the remote on/off input allows a BMS or other external device to disable charging when needed. With 46 days of historical data storage, you can review solar yield, battery voltage, and charge trends directly in the VictronConnect app.
Built for Australian Conditions
From the tropical north to the arid interior, Australian solar installations face extreme heat, dust, and humidity. The SmartSolar MPPT’s convection-cooled design eliminates fan failures, while the fully potted electronics resist moisture and corrosion. The controller derates power gracefully above 40°C, protecting itself and your batteries without sudden shutdowns.
Installation is straightforward with MC4 PV connectors for quick, weatherproof solar array connections and 35 mm² (AWG2) battery terminals that accept heavy-gauge cable for minimal voltage drop. The compact footprint (215 x 250 x 95 mm) and 3 kg weight make it easy to mount in tight spaces such as vehicle compartments or electrical cabinets.
