xVictron BlueSolar MPPT 150/70-Tr Solar Charge Controller
The Victron BlueSolar MPPT 150/70-Tr is a solar charge controller designed for professional off-grid and battery charging installations. It accepts a maximum PV open-circuit voltage of 150V and delivers up to 70A of charge current, making it suited to medium-to-large battery systems where efficient solar harvest is a priority. It is aimed at installers and system integrators working on caravans, boats, off-grid cabins, and commercial battery storage applications.
Key Features
- Maximum PV open-circuit voltage of 150V, allowing series-connected panel strings without a step-down transformer.
- 70A maximum charge current output, capable of charging 12V, 24V and 48V battery banks.
- True MPPT (Maximum Power Point Tracking) algorithm continuously finds the optimal operating point of the PV array, even under partial shading or variable irradiance.
- Tr (screw terminal) variant provides robust, field-serviceable wiring connections suitable for permanent installations.
- Compatible with a wide range of battery chemistries including flooded lead-acid, AGM, gel and lithium (with appropriate BMS).
- Victron VE.Direct communication port for monitoring and integration with the GX device ecosystem and VictronConnect app.
- Built-in Bluetooth connectivity via VictronConnect when used with the optional VE.Direct Bluetooth Smart dongle.
- Automatic battery voltage detection (12V, 24V, 48V) on first connection.
Product Overview
The BlueSolar MPPT 150/70-Tr sits in Victron's established BlueSolar range, which does not include built-in Bluetooth (unlike the SmartSolar series). This makes it a cost-effective choice where remote monitoring is handled via a GX device such as a Cerbo GX, or where direct VE.Direct wired communication is preferred. The 150V maximum input voltage gives installers flexibility when designing PV string configurations, particularly with 60-cell or 72-cell panels in series.
The 70A charge output is sufficient to deliver up to 3.5kW of charge power into a 48V battery bank, or proportionally less at lower voltages. The MPPT algorithm operates across the full input voltage range and responds quickly to changing conditions, which is particularly relevant in installations subject to shading, cloud cover or seasonal variation. The controller handles the conversion from higher PV string voltages down to battery voltage internally, so there is no need for additional voltage conversion equipment in the DC circuit.
The Tr designation refers to the screw terminal connection type. This is the standard choice for fixed installations where cables are terminated once and left in place. The unit weighs 3.88kg and is designed for wall or panel mounting in a sheltered enclosure or indoor location.

Installation Notes
This unit should be installed by a qualified electrician or experienced solar installer. The 150V maximum PV input voltage requires careful string design to ensure open-circuit voltage does not exceed this limit under cold-temperature conditions, which can raise Voc above standard test condition values. Ensure all DC wiring is correctly rated and fused in accordance with BS 7671 and any applicable IET Wiring Regulations. For off-grid systems connected to a generator or grid-tied inverter, verify compatibility with the wider system before commissioning. The BlueSolar MPPT 150/70-Tr is not a grid-tied inverter and does not require G98 or G99 registration.
