Victron energy MPPT 12V Manual página 3

1. General Description
1.1 PV voltage up to 100V
The charge controller is able to charge a lower nominal-voltage
battery from a higher nominal voltage PV array.
The controller will automatically adjust to a 12 or 24V nominal
battery voltage.
1.2 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.
1.3 Advanced Maximum Power Point Detection in case of
partial shading conditions
If partial shading occurs, two or more maximum power points
may be present on the power-voltage curve.
Conventional MPPTs tend to lock to a local MPP, which may not
be the optimum MPP.
The innovative SmartSolar algorithm will always maximize
energy harvest by locking to the optimum MPP.
1.4 Outstanding conversion efficiency
No cooling fan. Maximum efficiency exceeds 98%. Full output
current up to 40°C (104°F).
1.5 Extensive electronic protection
Over-temperature protection and power derating when
temperature is high.
PV short circuit and PV reverse polarity protection.
PV reverse current protection.
1.6 Internal temperature sensor
Compensates absorption and float charge voltages for
temperature.
1.7 Automatic battery voltage recognition
The controller will automatically adjust itself to a 12V or a 24V
system one time only.
If a different system voltage is required at a later stage, it must be
changed manually, for example with the Bluetooth app.
