Description
xVictron SmartSolar MPPT 100/20 Solar Charge Controller (up to 48V)
The Victron SmartSolar MPPT 100/20 is a solar charge controller supporting 12V, 24V and 48V battery systems, with a maximum PV open-circuit voltage of 100V and a maximum charge current of 20A. It is aimed at professional installers and off-grid system builders who need a reliable, Bluetooth-enabled MPPT controller in a compact form factor.
Key Features
- Maximum PV open-circuit voltage of 100V, compatible with 12V, 24V and 48V battery banks.
- 20A maximum charge current, suitable for small to medium off-grid and mobile solar installations.
- Built-in Bluetooth for direct configuration and monitoring via the Victron VictronConnect app on iOS and Android, with no additional dongle required.
- Advanced MPPT algorithm tracks the maximum power point rapidly, even under variable or partial shading conditions.
- Compatible with lithium (LiFePO4), AGM, gel, flooded and other lead-acid battery chemistries, with programmable charge profiles.
- Load output with programmable control algorithms, including battery life mode, to protect against deep discharge.
- Supports VE.Direct communication for integration with Victron GX devices, CCGX, Cerbo GX and the VRM online portal.
- Compact and lightweight at 0.74 kg, suitable for installation in confined spaces on boats, campervans and small off-grid cabins.
Product Overview
The SmartSolar MPPT 100/20 uses multi-point power tracking to extract the maximum available energy from the connected solar array. Unlike PWM controllers, MPPT technology converts excess panel voltage into additional charge current, which is particularly beneficial when panel voltage is significantly higher than battery voltage. This makes it well suited to systems where the PV string voltage sits well above the battery voltage, such as a 48V battery bank charged from a higher-voltage panel configuration.
The integrated Bluetooth module allows full configuration directly from a smartphone without needing a separate interface cable. Charge algorithm parameters, load output behaviour, battery type and voltage thresholds are all accessible through VictronConnect. For larger system installations, the VE.Direct port connects the unit to a Victron GX device, enabling centralised monitoring and data logging through the VRM portal. This makes the 100/20 a practical choice for both standalone installations and as part of a wider Victron ecosystem.
The load output can power DC loads directly from the controller, with programmable disconnect thresholds to prevent battery over-discharge. Battery life mode extends the usable life of lead-acid batteries in systems where solar input is intermittent or limited.

Installation Notes
Installation should be carried out by a qualified electrician or experienced solar installer. Ensure PV open-circuit voltage does not exceed 100V under any temperature conditions, including cold-weather Voc increases. Battery polarity must be connected correctly before connecting the PV array. For lithium battery installations, verify that the charge profile is correctly configured for the specific cell chemistry in use. Where this unit forms part of a grid-connected or hybrid system, relevant G98 or G99 notification requirements apply to the wider installation.
