The PV terminal of the inverter supports only the PV string input and cannot be connected
to other power supplies. Since the output of the PV string connected to the SUN2000
cannot be grounded, ensure that the PV module output is well insulated to ground.

During the installation of PV strings and SUN2000, the positive or negative terminals of
PV strings may be grounded if power cables are not properly installed or routed. In this
case, an AC or DC short circuit may occur and damage the SUN2000. This damage is not
covered under any warranty.
