1 General Description

1.1 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.
1.2 VE.Direct
For a wired data connection to a Color Control panel, PC or other devices
1.3 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.
1.4 Load output
Deep 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: see 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. A special interface cable may be needed,
please see section 3.7.
Alternatively, a BatteryProtect may be used to control the load. Please see our website
for specifications.
1.5 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.
1.6 Internal temperature sensor
Compensates absorption and float charge voltages for temperature. (range 6°C to 40°C)
1.7 Optional external voltage and temperature sensor
(range -20°C to 50°C)
The Smart Battery Sense is a wireless battery voltage-and-temperature sensor for Victron
MPPT Solar Chargers. The Solar Charger uses these measurements to optimize its charge
parameters. The accuracy of the data it transmits will improve battery charging efficiency,
and prolong battery life.
Alternatively, Bluetooth communication can be set up between a BMV-712 battery monitor
with battery temperature sensor and the solar charge controller
