Help please. I have 8kw Deye working perfectly as pure backup and ready for PV installation. My CT is placed on the incoming Eskom live with arrow facing direction of power to inverter. I have 2 non essential loads connected via EL to the Eskom supply before the inverter and obviously after the CT. I would like my CT to reflect the total load on my Eskom supply. Selecting Selling first still doesn't reflect my non essential load. It simply reflects the normal inverter house load. Should it work and if so what specific settings are required?

If I have a faulty device ( on the unbonded load ) side where the live or neutral has erroneously connected to the grounded frame and I touch that frame whilst standing on say wet ground how will current flow through me as there will be no potential difference between me and ground? If I am foolish enough to directly touch the floating live or neutral please explain the current path that would result in my demise without the earth leakage device tripping as it is my understanding that the toroidal transformer within the EL relay will detect an imbalance and trip. I would really appreciate some clarity on this as I cannot fathom out what happens when you touch an unreferenced floating potential. Do you simply jump to that potential? All of the above assuming grid off and unbonded inverter in operation.

At the end of load shedding when Eskom power returns my 8kw Deye remains in battery mode for 60 seconds. This effectively protects your entire electrical installation from any voltage or frequency abnormalities during stabilization of the grid. It does surely however mean that during those 60 seconds we have neutral to ground bonded at the pole and on the load side assuming there is a bonding relay in place. Thankyou for the excellent discussion on Neutral to Ground bonding on the load side of the inverter. Please comment on the protection provided by a normal EL relay connected at the inverter load output point when there is no bond between Neutral and ground.
