Victron BlueSolar MPPT 250/70-Tr VE.Can: High-Capacity Solar Charge Controller for 12V, 24V, and 48V Systems

Advanced MPPT Technology for Maximum Energy Harvest

The Victron BlueSolar MPPT 250/70-Tr VE.Can is a professional-grade solar charge controller engineered for large off-grid and grid-interactive systems. With a 70 A rated charge current and support for 12 V, 24 V, and 48 V battery banks, it efficiently manages up to 4000 W of solar input. Its ultra-fast Maximum Power Point Tracking (MPPT) algorithm ensures optimal energy capture even under rapidly changing light conditions, while advanced shading detection maximises output when partial cloud cover or obstructions occur.

Unlike generic PWM controllers, this MPPT unit converts excess voltage into usable current, delivering up to 30% more energy from the same array. The 250 V maximum open-circuit voltage allows long series strings, reducing cable losses and installation complexity. With a peak efficiency of 99%, minimal self-consumption, and natural convection cooling, it operates reliably in demanding environments without fan noise or maintenance.

VE.Can Networking for Scalable, Synchronised Systems

Parallel operation is a standout feature: up to 25 units can be synchronised via the VE.Can bus, enabling large-scale installations with coordinated charging. This makes the 250/70-Tr ideal for commercial off-grid sites, remote telecommunications, and residential systems requiring high reliability. The VE.Can interface also integrates with Victron GX devices (such as the Color Control GX) and the VRM portal for remote monitoring, firmware updates, and system control.

For local configuration, the controller includes a VE.Direct port compatible with the MPPT Control display or a Bluetooth Smart dongle (sold separately). A programmable relay and remote on/off terminal provide flexible load management, while the eight pre-programmed charge algorithms and user-definable settings accommodate lead-acid, lithium, and other battery chemistries.

Built for Harsh Australian Conditions

Rated IP43 for electronics and IP22 for connections, the BlueSolar 250/70-Tr withstands high humidity, dust, and temperature extremes from -30 °C to +60 °C. Full output is maintained up to 40 °C, with automatic derating above that to protect internal components. The robust aluminium housing and conformally coated circuit board resist corrosion, making it suitable for unconditioned indoor spaces such as sheds, equipment rooms, and marine engine compartments.

Heavy-duty 35 mm² (AWG2) terminals accept large gauge cable, minimising voltage drop and heat buildup. PV reverse polarity, output short circuit, and over-temperature protections safeguard both the controller and connected equipment.
