Victron Energy SmartSolar MPPT 75/10, 75/15, 100/15 & 100/20

Built-in Bluetooth Smart

The wireless solution for setting up, monitoring and updating the SmartSolar charge controller.

VE.Direct

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

Ultra-fast Maximum Power Point Tracking (MPPT)

Especially under overcast conditions, when the light intensity is constantly changing, an extremely fast MPPT controller improves energy yield by up to 30% compared to PWM charge controllers and by up to 10% compared to slower MPPT controllers.

Load output

Deep discharge of the battery can be prevented by connecting all loads to the load output. The load output disconnects the loads when the battery has been discharged to a predetermined voltage value.
(48 V model: interface to a relay) Alternatively, an algorithm for intelligent battery management can be selected: see BatteryLife. The load output is short-circuit proof.

Battery Life: intelligent battery management

If the solar charge controller is not able to charge the battery to its full capacity within a day, the battery status will constantly cycle between "partially charged" and "end of discharge". This mode of operation (no regular full charging) will damage a lead-acid battery within a few weeks or months.
The BatteryLife algorithm monitors the battery's state of charge and, if necessary, increases the load disconnection threshold day by day (i.e. the load is disconnected earlier) until the energy harvested is sufficient to charge the battery to nearly 100%. From this point, the load disconnection threshold is modulated so that the charge is near 100% approximately once a week.

Internal temperature sensor

Balances constant and float voltages according to temperature.

Option external battery voltage and temperature measurement via Bluetooth

A Smart Battery Sense or a BMV-712 Smart Battery Monitor can be used to transmit battery voltage and temperature data to one or more SmartSolar charge controllers.

Recovery function for fully discharged batteries

Will initiate charging even if the battery has been discharged to zero volts.
Reconnects to a fully discharged lithium-ion battery with internal disconnect function.
