5.6.1 AC Side Requirements
Only with the permission of the local grid department, the inverter can be connected
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 com
pany for help.
AC Circuit Breaker
WARNING
Over-current protection devices, such as AC circuit breakers and fuses, must be in
stalled on the AC side of the inverter and the grid side to ensure safe disconnection
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.

Multiple Inverters in Parallel Connection
When multiple inverters are connected to the grid in parallel, ensure that the maximum number
of inverters connected in parallel to a single winding of the box-type substation is 15. Otherwise,
please contact SUNGROW for technical scheme.
MV Transformer
The MV transformer used together with the inverter should meet the following requirements:
• A distribution transformer can be used if it is designed for the typical cyclical loads of a PV
system (there is load in the day and no load at night).
• A liquid-immersed type transformer or a dry type transformer can be used, and the shield
winding is not a requisite.
