Before.. I tried after the el but it tripped as soon as grid supply was restored ..

And done ... all working just fine ! 🙂

Thanks again for the advice Gents.. ive managed to get this far .. also please excuse my dc isolators..lol .. all I could find at my shop

Thank you so much for clearing this up Gents.. much appreciated

Hi Gents .. Lurking for some time now and I've finally got the balls to start my diy project .. I've got a sunsynk 5kw inverter and a sunsynk 5kw battery with it . I am NOT using solar at this stage and purely want to use my inverter as a ups during load shedding to power some essential circuits ie. Lights and plugs . I'm planning on installing tomorrow but need some last minute clarifications and I believe you lot of knowledgeable folks are my best bet 1. Do I need to use the temp sensor when using a Li-ion battery ? 2. The dreaded neutral earth bond that seems to be confusing a lot of people(including me). Do I need to hook up this relay if using inverter as a ups and also do I need a dedicated earth spike to feed neutral to earth via the relay or can I take earth from my grid supplied earth ? 3. Does the grid supply to inverter get taken before or after main db earth leakage? 4. CT coil needed when using as ups ? 5. Ac surge protection to inverter.. does this get connected on the grid side input to inverter ? 6. For a 5kw system is a 25a double pole isolator sufficient to feed the inverter "grid" supply ? 7. The PE marking on the inverter "grid" and "load" connections .do these just go to my normal grid supplied earth ? Apologies in advance for all the noobish questions.. I'm an auto electrician by trade and the transition from DC work all day everyday to doing AC work is a bit confusing..lol I'll appreciate any extra advice Thanks in advance ☺️
