OPTION
The solar charge controller built in option in the
inverter AJ is meant for charging a battery
exclusively from a solar generator.
Any other source of current needs an external
and suitable charge controller.
The maximum (open) voltage of the solar
generator is 23 V for 12 V systems, 46 V for 24 V
systems and 90 V for 48 V systems.
Connect firstly the inverter to the battery before
connecting the
adjustment mode is an I/Uuo ("floating") shunt
and it guarantees optimal charge conditions
along the battery lifetime.
The yellow indicator displays the functioning
mode:
Illuminated: The solar charge is at its
maximum.
Not illuminated: the solar generator is not
connected or the battery is
fully charged, or the solar
generator does not get solar
irradiation.

ONNECTION OF THE MODULES
On AJ 2100-S/2400-S inverters, a preinstalled cable (2 x 6mm2) replaces the terminals.
Wiring should be done through a connecting box.
 Positive (+) pole to the brown or red cable
 Negative (-) pole to the blue or black cable

NOTE: Since the solar charge controller
integrated in the AJ is of PWM type, it is
necessary to use 36 or 72 cell PV modules
(12V or 24V respectively). All other types of
PV modules require an MPPT charge
controller (i.e VarioTrack or VarioString).
V3.0
The battery is more than 95%
charged and the charger is in
"floating" mode to complete
the charge. The
frequency varies as per the
capacity of the battery and
the power of
generator.
