5.7. Electrical connection
5.7.1. Safety
DANGER
Danger to life due to lethal voltages!
High voltages which may cause electric shocks are present in the
conductive parts of the inverter. Prior to performing any work on
the inverter, disconnect the inverter on the AC and DC sides.
WARNING
Danger of damage to electronic components due to electrostatic
discharge.
Take appropriate ESD precautions when replacing and installing
the inverter.
5.7.2. Connection to the grid(AC)
Please connect AC cable obey the following procedures:
1.Switch off AC breaker and secure against being inadvertently switched back on.
About the AC breaker,please refer to the below form .
Types Max current output
Suggested AC switch spec
4.Insert the stripped and bared conductors L,N,PE into the screw terminals with
sign L,N,PE on the socket element and tighten the screws firmly.
5.Push the threaded sleeve into the socket element; screw the pressure screw
tightly onto the threaded sleeve;
2. The grid connection is made using 3 conductors (L, N, and PE),We recommend
the following requirements for Growatt 1000-S/ Growatt 1500-
S/Growatt 2000-S/Growatt 2500-S/Growatt 3000-S.

WARNING
You must install a separate single-phase circuit-breaker or other
load disconnection unit for each inverter in order to ensure that the
inverter can be safely disconnected under load.
NOTE: The inverter is equipped with integrated RCM(Residual
current operated monitor)and RCD(Residual current and protective
device) which are used for preventing from being electric shock. An
external built RCD in fact is not necessary .
If the network operator stipulate an external built RCD,you must
choose a residual-current protective device that triggers in the
event of residual current more than 300mA.
3.Remove the parts of the AC connection plug from the accessory bag.Guide the
pressure screw, sealing ring, threaded sleeve over the AC cable
