Victron SmartSolar MPPT Controller 75 / 10-15 & 100 / 15-20

More info

SmartSolar is all about functionality and options. These highly efficient ultra-fast Maximum Power Point Tracking (MPPT) solar charge controllers have it all - from high efficiency, optimal partial shading performance, programmable battery algorithms, street light functions and more. Smart is for built in Bluetooth for monitoring and control with VictronConnect. Options include remote monitoring over the internet via the VRM Portal, also a pluggable LCD display for the larger models.

Bluetooth Smart built-in: dongle not needed

The wireless solution to set-up, monitor and update the controller using Apple and Android smartphones, tablets or other devices.

VE.Direct

For a wired data connection to a Color Control panel, PC or other devices

Ultra fast MPPT tracking

Especially in case of a clouded sky, when light intensity is changing continuously, a fast MPPT algorithm 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. Alternatively, an intelligent battery management algorithm can be chosen: Battery
Life. The load output is short circuit proof. Some loads with high inrush current can best be connected directly to the battery. If equipped with a remote on-off input, these loads can be controlled by connecting the load output of the controller this remote on-off input. Alternatively, a BatteryProtect may be used to control the load. Please see our website for specifications.

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.

Internal temperature sensor

Compensates absorption and float charge voltages for temperature.

Automatic battery voltage recognition

The controller will automatically adjust itself to a 12V or a 24V system one time only. If a different system voltage is required at a later stage, it must be changed manually, for example with the Bluetooth app.

Three step charging

The controller is configured for a three step charging process: Bulk – Absorption - Float.

Bulk
During this stage the controller delivers as much charge current as possible to rapidly recharge the batteries.

Absorption
When the battery voltage reaches the absorption voltage, the controller switches to constant voltage mode. When only shallow discharges occur, the absorption time is kept short in order to prevent overcharging of the battery. After a deep discharge the absorption time is automatically increased to make sure that the battery is completely recharged. Additionally, the absorption period is also ended when the charge current decreases to less than 1A.

Float
During this stage, float voltage is applied to the battery to maintain a fully charged state. When the battery voltage drops below float voltage during at least 1 minute a new charge cycle will be triggered.

Configuring and monitoring

- Bluetooth Smart (built-in): connect to a smartphone or tablet running iOS or Android.
- Use the VE.Direct to USB cable (ASS030530000) to connect to a PC, a smartphone with Android and USB On-The-Go support (requires additional USB OTG cable).
- Use a VE.Direct to VE.Direct cable to connect to a MPPT Control or a Color Control panel.
