The SmartSolar MPPT solar charge controllers with load output from Victron Energy in the 75 volt series include the following four models 75/10, 75/15, 100/15, and 100/20.  The first number in the model name is the maximum PV open circuit voltage and the second number is the rated battery charge current.

Bluetooth Built-in

Remotely control and monitor the extensive features of your SmartSolar MPPT solar charger with built-in Bluetooth by pairing it with your smartphone or other device via the VictronConnect app.  A VE.Direct port enables 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-discharging 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 section below.  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

The charge controller starts a new charge cycle every morning, when the sun starts shining. There are lead acid, LiFePO₄, and user defined charging algorithms available.

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

The SmartSolar charge controller will initiate charging even if the battery has been discharged to zero volts.  It will also reconnect to a fully discharged Li-ion battery with integrated disconnect function.

      Notes 1a - If more PV power is connected, the controller will limit input power.
      1b - The PV voltage must exceed Vbat + 5V for the controller to start.  Thereafter the minimum PV voltage is Vbat + 1V
      2 - A PV array with a higher short circuit current may damage the controller.
