Description
xVictron BlueSolar MPPT 100/50 Solar Charge Controller
The Victron BlueSolar MPPT 100/50 is a solar charge controller designed for off-grid and battery-based solar systems. It accepts a maximum PV open-circuit voltage of 100V and delivers up to 50A of charge current, making it suited to small and medium installations where reliable battery charging is required. It is aimed at professional installers, system integrators and technically competent off-grid users.
Key Features
- Maximum PV open-circuit voltage of 100V, with a 50A maximum charge current output.
- MPPT (Maximum Power Point Tracking) algorithm continuously extracts the maximum available power from the connected solar array.
- Compatible with 12V and 24V battery systems, with automatic voltage detection.
- Supports lead-acid battery chemistries including flooded, gel and AGM, as well as lithium (LiFePO4) battery banks.
- Built-in load output for direct connection of DC loads, with low-voltage disconnect to protect the battery.
- Bluetooth connectivity available via the optional VE.Direct Bluetooth Smart dongle, enabling monitoring through the Victron Connect app.
- VE.Direct communication port for integration with Victron monitoring and control devices, including the Color Control GX and Venus GX.
- Compact and lightweight at 1.4kg, suitable for panel, wall or enclosure mounting.
Product Overview
The BlueSolar MPPT 100/50 uses Victron's MPPT charge algorithm to track the peak power point of the solar array in real time. This is particularly valuable when panel temperature changes or partial shading cause the power point to shift, as the controller adapts continuously rather than operating at a fixed voltage. The result is more energy harvested from the same array compared to PWM controllers, especially in cooler climates and variable UK weather conditions.
The 100V maximum PV input voltage allows for small series-connected panel strings, giving installers flexibility in array design without requiring a high-voltage MPPT unit. The 50A charge output is sufficient to charge a 12V or 24V battery bank from arrays up to approximately 700W (12V) or 1400W (24V). The VE.Direct port enables full integration into Victron's GX monitoring ecosystem, and the controller can be configured and monitored remotely when paired with compatible Victron hardware.
The built-in load output simplifies wiring in smaller off-grid systems by allowing DC loads to be connected directly to the controller. Low-voltage disconnect protects the battery from deep discharge, which is especially important in systems with lead-acid batteries where over-discharge causes permanent capacity loss.

Installation Notes
Installation should be carried out by a qualified electrician or experienced solar installer. Ensure the PV array open-circuit voltage does not exceed 100V under any conditions, including cold temperatures, which raise open-circuit voltage. Verify battery chemistry settings are correctly configured before commissioning. The VE.Direct port enables connection to Victron GX devices for system monitoring. This unit is not suitable for grid-tied applications and does not require G98 or G99 compliance. For lithium battery installations, confirm compatibility with the battery management system before connecting.
