I got a Axpert 5KVA + 4x100Ah and no PV (for the moment only load shedding backup).
My supply is 60A TN−C−S. It looks to me as if I don't have an earthing spike. Earth is bonded to Eskom's neutral right before the meter.
I'm using a changeover switch to disconnect Eskom and use the inverter. I understood that I have to bond the inverter's neutral to earth when I switch to inverter during load shedding. But where would I get 'earth'? CT seems to require a complete disconnect before I connect the inverter but typically one would - at the same time - create a connection to Eskom's neutral.
So 3 questions:
Can I trust Eskom's neutral to be bond to earth during loadshedding?
Can I used Eskom's neutral/earth to bond my inverter's neutral?
