Victron BlueSolar MPPT 100/50 Solar Charge Controller | SCC020050200

The Victron BlueSolar MPPT 100/50 is a solar charge controller built for off-grid and battery-based solar systems. It handles a maximum PV open-circuit voltage of 100V and delivers up to 50A of charge current, putting it in the range of small to medium installations that need dependable battery charging. It suits professional installers, system integrators and technically confident off-grid users.

Key features of the MPPT 100/50 charge controller

• PV input, maximum open-circuit voltage of 100V
• Charge current, up to 50A output
• Battery compatibility, 12V and 24V systems with automatic voltage detection
• Battery chemistries, flooded, gel, AGM and lithium (LiFePO4)
• Load output, built in, with low-voltage disconnect to protect the battery
• Connectivity, VE.Direct port, plus Bluetooth via the optional VE.Direct Bluetooth Smart dongle and Victron Connect app

Victron's MPPT algorithm tracks the peak power point of the array continuously, adjusting as panel temperature or shading shifts that point rather than sitting at a fixed voltage. This tends to pull more energy from the same array than a PWM controller, particularly in cooler and changeable weather. The 100V PV input allows for small series-connected panel strings without stepping up to a higher-voltage MPPT unit, and the VE.Direct port lets the controller integrate with Victron's GX monitoring devices, including the Color Control GX and Venus GX.

Applications

Fits off-grid cabins and rural buildings on 12V or 24V battery systems, marine and narrowboat installations, motorhome and campervan setups with moderate panel capacity, and telecoms or remote monitoring equipment running on solar and battery. It also works well in small agricultural installations and solar-backed battery systems for security or lighting.

Installation notes

Fitting should be done by a qualified electrician or experienced solar installer. The PV array's open-circuit voltage must stay under 100V in all conditions, including cold weather, which raises open-circuit voltage. Battery chemistry settings need to be confirmed before commissioning, and for lithium banks the battery management system compatibility should be checked first. This unit is not intended for grid-tied use.
