xVictron SmartSolar MPPT 150/70-Tr Solar Charge Controller
The Victron SmartSolar MPPT 150/70-Tr is a solar charge controller with a 150V maximum PV open-circuit voltage and a 70A charge current output. It is designed for professional off-grid and battery-based solar installations where accurate battery charging and remote monitoring are required. Built-in Bluetooth allows direct configuration and monitoring without additional hardware.
Key Features
- 150V maximum PV input voltage, suitable for series-connected panel strings in 12V, 24V and 48V battery systems.
- 70A maximum charge current, supporting substantial battery bank charging from a single controller.
- True MPPT algorithm continuously tracks the maximum power point, extracting more energy from the panels compared to PWM controllers, particularly in variable light conditions.
- Built-in Bluetooth (VictronConnect) for wireless configuration, real-time monitoring and firmware updates directly from a smartphone or tablet.
- TR (screw terminal) connection type for reliable, field-serviceable wiring on PV and battery connections.
- Compatible with lithium (LiFePO4), AGM, gel, flooded and other battery chemistries via configurable charge algorithms.
- Load output functionality allows direct connection of DC loads with programmable control based on battery state of charge.
- VE.Direct port for integration with Victron GX devices, Cerbo GX, and the VRM online monitoring portal.
Product Overview
The SmartSolar MPPT 150/70-Tr uses a multi-stage adaptive charge algorithm that adjusts in real time to battery condition and temperature. The MPPT tracking speed is fast enough to respond to rapidly changing irradiance, which matters on partly cloudy days when a slower tracker would leave energy on the table. The 150V PV input ceiling gives installers flexibility to wire panels in longer series strings, reducing cable losses and simplifying array layouts on larger rooftop or ground-mount systems.
The TR variant uses screw terminals rather than MC4 or Anderson connectors, which is the preferred termination method for many professional installations where cable management and long-term serviceability are priorities. The VE.Direct port connects directly to Victron GX devices such as the Cerbo GX, enabling full system integration, data logging and remote access via the VRM portal. This makes the 150/70-Tr a practical choice for installations where ongoing remote monitoring is part of the service agreement.
Battery chemistry configuration is handled through VictronConnect, where charge voltages, absorption time and temperature compensation can all be set precisely. For lithium batteries, a dedicated LiFePO4 algorithm is available, and the controller can accept a signal from a Victron Battery Management System to halt charging when required.

Installation Notes
Installation should be carried out by a qualified electrician or experienced solar installer. The PV input can reach 150V open-circuit, which is a hazardous voltage requiring appropriate precautions during wiring and commissioning. Ensure PV string voltage does not exceed the 150V maximum under any temperature condition, including cold-weather Voc rise. Battery connections must be fused appropriately and sized for the 70A charge current. For systems integrated with a GX device and connected to the VRM portal, network configuration should be completed as part of commissioning. Lithium battery installations must use a compatible BMS and follow the battery manufacturer's integration requirements.
