Victron energy Blue Power MPPT 100/15 Anleitung Seite 7

● Recommended number of cells for highest controller efficiency: 72
(2x 12V panel in series or 1x 24V panel).
● Maximum: 144 cells 4x 12V panel in series).
24V battery and mono- or polycristalline panels
● Minimum number of cells in series: 72
(2x 12V panel in series or 1x 24V panel).
● Maximum: 144 cells (4x 12V panel in series).
Note: at low temperatures the open circuit voltage of a 144 cell solar array may exceed
100V, depending on local conditions and cell specifications. In that case the number of
cells in series must be reduced.
3.4. Configuration of the controller (see figure 1 and 2)
There is a 4-pin connector available to select one of the three battery control options:
● No bridge: BatteryLife algorithm (see 1.2.2.)
● Bridge between pin 1 and pin 2: conventional (see 1.2.1.)
Low voltage load disconnect: 11,1V or 22,2V
Automatic load reconnect: 13,1V or 26,2V
● Bridge between pin 2 and pin 3: conventional (see 1.2.1.)
Low voltage load disconnect: 11,8V or 23,6V
Automatic load reconnect: 14V or 28V
3.5 LEDs
Green LED: indicates which load output control algorithm has been chosen.
On: one of the two conventional load output control algorithms (see Fig 2)
Blinking: BatteryLife load output control algorithm (see Fig 2)
Yellow LED: signals charge sequence
Off: no power from PV array (or PV array connected with reverse polarity)
Blinking fast: bulk charge (battery in partially charged state)
Blinking slow: absorption charge (battery charged to 80% or more)
On: float charge (battery fully charged)
3.6 Cable connection sequence (see figure 3)
First: connect the cables to the load, but ensure that all loads are switched off.
Second: connect the battery (this will allow the controller to recognize system voltage).
Third: connect the solar array (when connected with reverse polarity, the controller will heat
up but will not charge the battery).
The system is now ready for use.
