If any, what din mount changeover switch do you use/prefer. 

Any recommendation for online electrical wholesales. (ACDC and RS excluded)

i tend to use the Hager 63A changeover, found it to be the most stable over the last 5 years, on the smaller off grid installs i have used the Hager 40A between genie and inverter

Just looked at them on one site... Wants the Changeover to be the same as the rest of the breakers to ensure uniformity. The hager range might just fit the application. 

I have a Hager changeover as well. Reasonably priced, feels quite solid, and does the job.

I used this one and comfortable fornme

Also use them with happiness!! Try ElctroMechanica online store - has big Hager selection.

Those Hager changeover switches work very well and are of good quality

On the diagram, what is 'PLN'

I understand load = Eskom 220V? and INV Out = inverter output/220V?

I put from the grid/Eskom

LOAD - Supply to DB from change over switch  

PLN - Eskomsepush

INV Out - 220V supply coming from inverter
