5.6 AC Cable Connection
5.6.1 AC Side Requirements
Only with the permission of the local grid department, the inverter can be con-
nected to the grid.
Before connecting the inverter to the grid, ensure the grid voltage and frequency comply with
requirements, for which, refer to "Technical Data" . Otherwise, contact the electric power
company for help.
AC Circuit Breaker
Over-current protection devices, such as AC circuit breakers and fuses, must be
installed on the AC side of the inverter and the grid side to ensure safe disconnec-
tion between the inverter and the grid.
• Do not connect any local load between the inverter and the AC circuit breaker
except for the tracking axis.
• Multiple inverters cannot share one AC circuit breaker.
