Victron Energy SmartSolar MPPT 75/15 Charge Controller

Bluetooth Smart built-inThe wireless solution to set-up, monitor, update and synchronise SmartSolar Charge Controllers.VE.DirectFor 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 outputOver-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 managementWhen 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 algorithmSee the software section on Victron Energy website for more details.Day/night timing and light dimming optionSee the software section on Victron Energy website for more details.Internal temperature sensorCompensates absorption and float charge voltage for temperature.Optional external battery voltage and temperature sensing via BluetoothA 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 functionWill initiate charging even if the battery has been discharged to zero volts.Will reconnect to a fully discharged Li-ion battery with integrated disconnect function.
