● 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 the SUN2000, the positive or negative
terminals of PV strings may be short-circuited to ground if the power cable is
not properly installed or routed. In this case, an AC or DC short circuit may
occur and damage the SUN2000. The caused device damage is not covered
under any warranty.
