xVictron SmartSolar MPPT 150/70-Tr Solar Charge Controller
The Victron SmartSolar MPPT 150/70-Tr is a solar charge controller rated for a 150V maximum PV input voltage and 70A charge current. It is designed for professional off-grid and battery-based solar installations where accurate maximum power point tracking and remote monitoring are required.
Key Features
- 150V maximum PV open-circuit voltage with 70A maximum charge current output.
- Built-in Bluetooth via the VictronConnect app for configuration, monitoring and firmware updates without additional hardware.
- MPPT algorithm continuously tracks the maximum power point, maximising energy harvest across varying light and temperature conditions.
- Compatible with 12V, 24V and 48V battery banks, with automatic voltage detection.
- TR (screw terminal) connection type for secure, industry-standard wiring.
- Supports multiple battery chemistries including flooded, AGM, gel and lithium (LiFePO4) with programmable charge profiles.
- VE.Direct port for integration with Victron GX devices, CCGX, Cerbo GX and Venus OS systems.
- Integrated load output for direct connection of DC loads with programmable control algorithms.
Product Overview
The SmartSolar MPPT 150/70-Tr uses a multi-stage MPPT algorithm to extract the maximum available power from a connected PV array. The 150V input ceiling gives installers flexibility when designing series or series-parallel string configurations, particularly in 24V and 48V systems where higher string voltages improve efficiency and reduce cable losses.
The built-in Bluetooth removes the need for a separate dongle during commissioning. Using VictronConnect on a smartphone or tablet, an installer can set battery type, absorption and float voltages, load output behaviour and temperature compensation. Historical data including yield, battery state and error logs are accessible directly from the app without requiring a GX device on site.
For permanent monitoring and integration into larger energy systems, the VE.Direct port connects to Victron GX devices such as the Cerbo GX. This enables full system visibility through the VRM portal, including remote firmware updates and data logging. The unit is housed in a metal enclosure with screw terminals (TR), suited to fixed panel or cabinet installations.

Installation Notes
Installation should be carried out by a qualified electrician or MCS-accredited installer familiar with DC solar systems. The PV open-circuit voltage must never exceed 150V under any temperature condition, including cold-start scenarios. Verify string Voc at minimum expected temperature before connecting. For lithium battery banks, confirm charge profile compatibility with the battery BMS before commissioning. When integrating with a Victron GX device or grid-tied system, follow the relevant wiring and communication guidelines for your installation type.
