NOTICE

•  When using built-in meters for networking in a parallel system, only the master inverter needs to 

connect CT cable.

•  Please use the CT connection cable shipped in the attachment.
• 

Inverter DO signal communication port, can be connected to dry contact signal with specification 
parameters: Max ≤ 24Vdc, 1A.

• 

EMS communication port: used to connect with the third party device. Third-party EMS device is 

not supported in parallel system.

•  In the parallel system, if you want to realize the DRED and RCR functions, you need only to 

connect the DRED and RCR communication cables to the master inverter; To achieve remote 
shutdown function, the remote shutdown communication cables needs to be connected to all 
inverters. 

• 

To ensure communication quality, please connect the parallel communication port PAR1 of one 
inverter to the parallel communication port PAR2 of another inverter.

•  Other cables shall be prepared by the customer.
•  To ensure the waterproof level of the inverter, do not remove the unused waterproof plugs of 

communication port on the inverter.
