SPD’s fail in 2 ways. 1) open circuit 2) Short circuit These MCB’s on there to protect against short circuit scenario 2) The sizing is related to the cable size. It is there to protect cable. It is also in the Sunsynk manual, but on the earth wire. Does the same thing. Kind Regards Jason

This is the drawing I was also using that was confusing me. I agree, this is not how a typical installation in SA is done. I followed the drawing from @ianm but the earthing was not show. Thank you so much for all the advice and input. Really appreciated. Kind Regards Jason

Also attended this “Meet and Greet” and also found this interesting.

Thank you so much for your resource. Really appreciated!

Hi, When wiring the CT with the arrow pointing towards the Inverter Supply, I am getting a negative reading. I have flipped the Coil to get a positive reading What can I be doing wrong and should I be worried about it if receiving a positive value. Terminal 5 - White Terminal 6 - Black Any comment will be appreciated. Thank you Kind Regards Jason

Hi Abe, Thanks for your reply. That is how I have it now and all working 100%. Was just concerned that the Inverter Itself if not protected by the RCD. Kind Regards Jason

I am supplying my Sunsynk 8kW Inverter with a dedicated Earth Leakage. This earth Leakage trips immediately. Anyone supplying their unit with a dedicated E/L successfully Other Info: 1) Have the Earth Bond Relay installed and functions as expected. 2) The UPS output supplies another E/L used for dedicates Essential Loads 3) Essential Loads have its own Dedicated Neutral Bar Any advice will be appreciated. Kind Regards Jason

Thank you ianm for a great drawing! I know this is an old Post, but this is how I plan to wire mine up. It makes perfect sense. My question is regarding the Earth Wire 1) I assume that the main earth wire from the Grid is wired to the Grid "Input" terminal on Inverter. 2) I am confused about the Earth wire on the Load Side. Must this be wired from the Load terminal on the Inverter to the Earth bar? OR should I use the "DB earth" that was bonded on the load side? Any help will be appreciated! Kind Regards Jason
