WARNING
• Check the positive and negative polarity of the PV strings, and connect the PV
connectors to corresponding terminals only after ensuring polarity correctness.
• During the installation and operation of the inverter, please ensure that the positive
or negative poles of PV strings do not short-circuit to the ground. Otherwise, an
AC or DC short-circuit may occur, resulting in equipment damage. The damage
caused by this is not covered by the warranty.
