6.4 Connecting the AC Output Cable

Do not connect loads between the inverter and the AC switch directly connected to the
inverter.
An AC circuit breaker shall be installed on the AC side to make sure that the inverter can safely
disconnect the grid when an exception happens. Select the appropriate AC circuit breaker in
compliance with local laws and regulations. Recommended AC circuit breakers:
Inverter
model
For single inverter
GW1600-MIS
GW1800-MIS
GW2000-MIS
Select and Install RCD depending on local laws and regulations. Type A RCDs (Residual Current
Monitoring Device) can be connected to the inverter for protection when the DC component
of the leakage current exceeds the limit value. For the system with a power below 30kW, it is
recommended to use an RCD with a specification of 300mA. For the system with a power above
30kW, an RCD specification of 10mA per kVA is recommended.
• Pay attention to the silkscreens L, N and PE on the AC connector. Connect the wires to
the corresponding terminals. The inverter may be damaged if the wires are connected
inappropriately.
• Make sure that the whole cable cores are inserted into the AC connector. No part of the
cable core can be exposed.
• Make sure that the cables are connected securely. Otherwise, the connector may be too
hot to damage the inverter when the inverter is working.
• Seal the AC connector using a sealing plug when it is not to be used. Otherwise, the ingress
protection rating will be influenced.
• The AC cable should be prepared by the customer. Recommended specifications: 4mm
6mm .
