Description

This is the popular Victron SmartSolar MPPT 100/20 Solar Charge Controller. Check the list of advanced features and you’ll quickly understand why this controller is the preferred option for smaller systems. Support for 12V, 24V, & 48V battery platforms and all chemistries means you can design your system with the future in mind.

Processing 20A of power places this controller at the  is part of Victron’s advanced line of controllers. Using the latest, fastest technology, SmartSolar controllers maximize this energy-harvest, driving it intelligently to achieve full charge in the shortest possible time. SmartSolar maintains battery health, extending its life.

With processing power of 290W on a 12V battery platform, or 580W on a 24V platform, or 1160W on a 48V platform, this controller can support a wide range of solar array sizes, and is a great fit for cabins, van conversions, RVs, and boats. The 100V input range provides you with the latitude to design your solar array for series or parallel configuration as required. Even in cold Canadian winter weather where voltage rise can wreak havoc on lesser controllers.

SmartSolar MPPT 100/20 Features

Bluetooth Smart built-in
The wireless solution to set-up, monitor, update and synchronize SmartSolar Charge Controllers.

VE.Direct
For a wired data connection to a Color Control GX, other GX products, PC or other devices.

Ultra-fast Maximum Power Point Tracking (MPPT)
Especially in case of a clouded sky, when light intensity is changing continuously, an ultra-fast MPPT controller will improve energy harvest by up to 30% compared to PWM charge controllers and by up to 10% compared to slower MPPT controllers.

Load output
Over-discharge of the battery can be prevented by connecting all loads to the load output. The load output will disconnect the load when the battery has been discharged to a pre-set voltage (48V model: interface with a relay).
Alternatively, an intelligent battery management algorithm can be chosen: see Battery Life.
The load output is short circuit proof.

Battery Life: intelligent battery management
When a solar charge controller is not able to recharge the battery to its full capacity within one day, the result is often that the battery will continually be cycled between a ‘partially charged’ state and the ‘end of discharge’ state. This mode of operation (no regular full recharge) will destroy a lead-acid battery within weeks or months.
The Battery Life algorithm will monitor the state of charge of the battery and, if needed, day by day slightly increase the load disconnect level (i.e. disconnect the load earlier) until the harvested solar energy is sufficient to recharge the battery to nearly the full 100%. From that point onwards, the load disconnect level will be modulated so that a nearly 100% recharge is achieved about once every week.

Programmable battery charge algorithm
See the software section on the Victron website for details

Day/night timing and light dimming option
See the software section on the Victron website for details

Internal temperature sensor
Compensates absorption and float charge voltage for temperature.

Optional external battery voltage and temperature sensing via Bluetooth
A Smart Battery Sense or a BMV-712 Smart Battery Monitor can be used to communicate battery voltage and temperature to one or more SmartSolar Charge Controllers.

Fully discharged battery recovery function
Will initiate charging even if the battery has been discharged to zero volts.
Will reconnect to a fully discharged Li-ion battery with integrated disconnect functionRemote
