Damage to the product caused by incorrect wiring is not covered by the warranty.
• Electrical connection must be performed by professionals.
• All cables used in the PV generation system must be firmly attached, properly
insulated, and adequately dimensioned.
Check the positive and negative polarity of the PV strings, and connect the PV con-
nectors 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.
Comply with the safety instructions related to PV strings and the regulations re-
lated to the local grid.
