Victron Blue Solar MPPT 75/15 (12/24V) Regulator
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 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. Alternatively,
an intelligent battery management algorithm can be chosen: see Battery Life.
The load output is short circuit proof. Some loads
(especially inverters) can best be connected directly to the battery, and the
inverter remote control connected to the load output. A special interface cable
may be needed, please see the manual.
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.

1a) If more PV power is connected, the controller will
limit input power to the stated maximum.
1b) PV voltage must exceed Vbat + 5V for the controller
to start. Thereafter minimum PV voltage is Vbat + 1V
2) A PV array with a higher short circuit current may
damage the controller.
