Multiplus II Isolation re- VE.can negative reverse current

Recomendations from wiring unlimited suggest the following wiring diagram to avoid reverse current down the Ve.Can bus.

(DC side) Regs require invertors to have double pole isolation of the invertor array, but I would also like to isolate each invertor individually for maintenance.

I have ammended the diagram below to show isolation per invertor, leaving the negative connected. Is this acceptable to avoid reverse current potential on disconnection of one invertor in the array and still allowing full isolation of the array?

A positive only disconnect is acceptable when placed between the inverter and bus bar.
