Since the output of the PV string connected to the solar inverter cannot be grounded,
ensure that the PV module output is well insulated to ground.
During the installation of PV strings and the solar inverter, 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 solar
inverter. The caused device damage is not covered under any warranty.
The solar inverter supports Y type terminals.
