Danger to life due to a high voltage inside the inverter!
• Be sure to use special insulation tools during cable connections.
• Note and observe the warning labels on the product, and perform operations
strictly following the safety instructions.
• Respect all safety instructions listed in this manual and other pertinent
documents.
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
connectors to corresponding terminals only after ensuring polarity correctness.
• During the installation and operation of the inverter, please ensure that the posi-
tive or negative poles of PV strings do not short-circuit to the ground. Other-
wise, an AC or DC short-circuit may occur, resulting in equipment damage. The
damage caused by this is not covered by the warranty.
• Do not connect any load between the inverter and the AC circuit breaker di-
rectly connected to it, so as to prevent the switch from tripping by mistake.
• Determine the specifications of AC switch strictly in compliance with the appli-
cable local laws and regulations and safety standards or the recommendation
by SUNGROW. Otherwise, the switch may not open in time in the event of some-
thing abnormal, which may then lead to safety incidents.
Comply with the safety instructions related to PV strings and the regulations re-
lated to the local grid.
