Victron SmartSolar MPPT 100/50 Solar Charge Controller | SCC110050210

The Victron SmartSolar MPPT 100/50 is a solar charge controller built for 12V and 24V battery systems, with a maximum PV open-circuit voltage of 100V and a maximum charge current of 50A. It suits off-grid installations, narrowboats, motorhomes and small commercial solar setups that need dependable battery charging.

Key features

• PV input, maximum open-circuit voltage of 100V, working with a range of panel configurations.
• Charge current, up to 50A, for 12V and 24V battery banks.
• Bluetooth, built in, paired with the VictronConnect app for wireless monitoring and setup.
• MPPT tracking, an adaptive algorithm follows the maximum power point as light levels change.
• Battery compatibility, lithium (LiFePO4), AGM, gel and flooded, with configurable charge profiles.
• Load output, programmable low-voltage disconnect, plus streetlight and timer functions.
• VE.Direct port, connects to Victron GX devices, the MPPT Control display and other Victron equipment.

Product overview

A multi-stage adaptive charging algorithm adjusts to battery condition and temperature. The MPPT tracking responds quickly to changing irradiance, which suits UK weather where cloud cover shifts frequently. Compared with a PWM controller, it draws more usable energy from the panels, particularly under partial shading or low light.

Built-in Bluetooth removes the need for a separate dongle. The VictronConnect app gives full configuration access, live data, yield history and fault logs. The VE.Direct port also connects to a Cerbo GX or similar device for monitoring through the VRM portal.

The load output switches a 12V or 24V feed for small DC loads, with a configurable low-voltage disconnect to protect the battery. The streetlight function switches on a timer or light sensor, useful for remote lighting without an extra controller.

Applications

Off-grid cabins and homes on 12V or 24V battery banks, narrowboats and canal boats, motorhomes and caravans, remote telecoms or monitoring equipment, agricultural off-grid power, and solar lighting or security systems using the load output.

Installation notes

Fit by a qualified electrician or experienced solar installer. Keep the PV array open-circuit voltage under 100V at all temperatures, including cold-weather peaks. Confirm the battery chemistry and voltage settings before commissioning, and follow BS 7671 for any connected DC or AC installation.
