Victron MPPT Charge Controller BT 75/10 75/15 100/15 100/20

Victron MPPT SmartSolar Charge Controller 75/10 – 75/15 – 100/15 – 100/20

Integrated Bluetooth Smart
The wireless solution to configure, monitor, update, and synchronize SmartSolar Charge Controllers.

VE.Direct
For cable data connection to Color Control GX or other GX devices, PC, or other devices. For remote installations, even when there are no internet connections nearby, you may be able to monitor your MPPT by connecting the GlobalLink 520.

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

DC 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 a ‘end of discharge’ state. This mode of operation (no regular full charge) will destroy a lead-acid battery within weeks or months. The BatteryLife 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 100% state. 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
Day/night timing and light dimming option
Internal temperature sensor – Compensates absorption and float charge voltages 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 start charging even if the battery has been discharged to zero volts. Will reconnect to a fully discharged Li-ion battery with integrated disconnect function.
