Damage to the product caused by incorrect wiring is not covered by the warranty.
• Electrical connection must be performed by professionals.
• Please use measuring devices with an appropriate range. Overvoltage can dam-
age the measuring device and cause personal injury.
• All cables used in the PV generation system must be firmly attached, properly
insulated, and adequately dimensioned.
• Do not damage the ground conductor. Do not operate the product in the ab-
sence of a properly installed ground conductor. Otherwise, it may cause per-
sonal injury or product damage.
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.
The interfaces of the battery in the system must be compatible with the inverter.
The entire battery voltage range must be completely within the permissible range
of the inverter, and the battery voltage shall not exceed the maximum permissible
DC input voltage of the inverter.
• Comply with the safety instructions related to PV strings and the regulations re-
lated to the local grid.
• Install the external protective grounding cable first when performing electrical
connection and remove the external protective grounding cable last when re-
moving the inverter.
