Studer AJ 350-24 - Models with Built - in Solar Charger

STUDER Innotec AJ
AJ V2.7 12/50
MODELS WITH BUILT-IN SOLAR CHARGER
(OPTION – S)
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 solar generator. The
adjustment mode is a I/Uuo (“floating”) shunt
and it guarantees optimal charge conditions
along the battery lifetime.
The yellow indicator displays the functionning
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.
Blinking : The battery is more than 95% charged
and the charger is in “floating” mode to complete
the charge. The blinking frequency varies as per
the capacity of the battery and the power of the
solar generator.
On AJ 2100-S/2400-S inverters, a preinstalled cable (2 x 6mm2) replaces the terminals.
Wiring should be done through a connecting box.
Connection:
Positive (+) pole to the brown or red cable.
Negative (-) pole to the blue or black cable
