STUDER INNOTEC
Model with built-in solar charger
The AJ inverters of the AJXXXX-S series
have a built-in solar charger. The built-in solar
charge controller is of the shunt and floating
type. It may only be used by solar
generators. The maximal voltage of the solar
modules is 23 V for 12 V applications and 46
V for 24 V applications. To fix it, first install
the cables of the inverter observing the
following instructions BEFORE connecting
the solar cells.
Then install the cables of the solar generator
observing the polarities (red for the + and
black for the -).
