drew137 Posted April 22, 2021 Share Posted April 22, 2021 Hi everyone, There is so much useful information here it is great! But it has made me confused! I thought I had my wiring plan sorted - would anyone be able to confirm which on the attached images is the correct way to go, from my reading/understanding the AC input to the inverter must be before the main DB E/L. The sub-DB (inverter DB) must have and E/L after the main breaker. I will be moving the L & N lines for the inverter supplied circuts to the sub-DB - at this stage I am not installing a changeover switch, this will come in the next few weeks and therefore is not shown in the attached. Battery supply is also not shown, I do have batteries with a correctly sized fuse on the positive DC line. Quote Link to comment Share on other sites More sharing options...
Coulomb Posted April 24, 2021 Share Posted April 24, 2021 The second case: inverter before any earth leakage. You need earth leakage after the inverter, and you have that in both diagrams. Energy-Jason 1 Quote Link to comment Share on other sites More sharing options...
