Digital isolators for multiple energymeters in the same SPI bus

Hi All,

 

I am working on a project which requires energy to be monitored at multiple points of load. All of these energy metering ICs have to be on the same SPI bus. I am not sure if I need isolation for the SPI lines of every ADE7xxx or just before my controller. Please advice. Thanks in advance.
