February 13, 20197 yr So today I installed a new 5KVa Axpert. It connects to the plugs and lights (on EL) via a SF2P-63A which separates Grid power from Inverter power Now for a strange one: Everything was working fine before load shedding with the ACDC 2 pole change over working like a charm. Load shedding came and 3.5hrs later we were back to Grid power. Switched change over back to Grid and all fine. Switched power on to charge Inverter and all fine. 10 Minutes later EL tripped - no problem switched all circuits off. Will not reset. Change over to all off (middle position) EL resets. Switch to Grid power and EL trips immediately even with all breakers down. Now switch to inverter, and EL resets. Even with inverter being charged (circuit from main switch with own EL - sub DB), EL still good. Even if I unplug the mains to inverter for charge (at this stage it still goes through a plug - will go through breaker tomorrow) with change over set to Grid, still full trip. Interim solution - Back to running lights and plugs on EL from inverter. Inverter connected to grid via a secondary circuit (sub DB with own EL) and no trips. So what is common: Earth from Axpert inverter output is connected to Earth at Main DB. I have a few LED circuits which seems to have a leakage (flashing LED's). So tomorrow the search starts, only question is where and how? I have includes a schematic of the installation for ease of reference Any advise would be appreciated, and if this post is in the wrong section, please move tks Cardiff Inverter.pdf
