1.5 Intended Use
The APS is a hybrid inverter that converts the direct current from a DC source into
alternating current and feeds it into the grid and vice versa. The product may be used
solely in photovoltaic systems, energy storage systems and as STATIC VAR
COMPENSTATION (STATCOM).
Connection to the medium-voltage grid is provided with the aid of a distribution
transformer.
The product is constructed for outdoor use. It fulfils the IP65 degree of protection.
The product is not suitable for operation in areas with the risk of explosion and must be
kept away from flammable or combustible materials.
It is prohibited to open the product when it is raining or the humidity is greater than
95%.
For all work appropriate tools must be used.
Only operate the product with the maximum permissible connected loads stated in the
Section Technical Data.
