Description
xVictron SmartSolar MPPT 250/70-Tr Solar Charge Controller
The Victron SmartSolar MPPT 250/70-Tr is a high-voltage solar charge controller designed for professional off-grid and battery-based solar installations. It accepts a maximum PV open-circuit voltage of 250V and delivers up to 70A of charge current, making it well suited to larger 12V, 24V or 48V battery systems. Built-in Bluetooth allows direct monitoring and configuration via the VictronConnect app without additional hardware.
Key Features
- Maximum PV input voltage of 250V DC, with a 70A maximum charge current output.
- Compatible with 12V, 24V and 48V battery systems, with automatic voltage detection.
- Built-in Bluetooth for configuration and monitoring via the VictronConnect app on iOS and Android.
- True MPPT tracking algorithm responds rapidly to changing light conditions, maximising energy harvest throughout the day.
- TR (screw terminal) connection type for secure, reliable wiring in fixed installations.
- Load output function allows direct connection of DC loads with programmable control options.
- Compatible with Victron GX devices and the VRM online monitoring portal for remote system oversight.
- Supports lithium (LiFePO4), AGM, gel, flooded and other battery chemistries with configurable charge algorithms.
Product Overview
The 250/70-Tr sits in the upper range of Victron's SmartSolar MPPT lineup. The 250V maximum PV voltage allows the use of longer PV strings with more panels in series, which reduces cable losses and gives installers more flexibility in system design. At 70A output, it can deliver up to 3360W of charge power into a 48V battery bank, or proportionally less at lower battery voltages.
The integrated Bluetooth removes the need for a separate Bluetooth dongle, which is required on older Victron MPPT models. Using VictronConnect, an installer can set battery type, charge voltages, absorption time, load output behaviour and streetlight functions directly from a phone or tablet. For permanent remote monitoring, the controller connects to Victron GX devices (such as the Cerbo GX) via VE.Direct, feeding data into the VRM portal.
The screw terminal (Tr) variant uses conventional screw-type PV and battery connections rather than MC4 or other connector formats. This suits panel installations where cables are terminated and routed through conduit, and is the standard choice for most fixed commercial and off-grid installations.

- Marine and narrowboat installations requiring a high-voltage PV input with Bluetooth monitoring.
- Mobile or vehicle-based systems (large vehicles, expedition builds) with substantial solar array capacity.
- Hybrid systems where a GX device coordinates solar, battery and generator or inverter/charger inputs.
- Agricultural and rural off-grid sites where remote VRM monitoring is required.
What Is Included
- Victron SmartSolar MPPT 250/70-Tr charge controller (1 unit)
Installation Notes
This controller operates at up to 250V DC on the PV input. DC voltages at this level are hazardous and must be handled by a qualified electrician or accredited solar installer. Ensure the PV string open-circuit voltage does not exceed 250V under any temperature conditions, including cold-weather Voc rises. Battery fusing and correct cable sizing are required in accordance with BS 7671 and any applicable system design standards. For systems integrated with a GX device or connected to the VRM portal, VE.Direct cabling and network configuration should be completed by someone familiar with Victron system architecture.
