Hi everyone, I’ve just received a new Multiplus 2-GX and have encountered an issue during testing. I connected a battery, applied 240Vac to the input, and connected a 30W light to the output. The inverter powers the light initially, but approximately every 4 minutes, it makes a clicking sound, the light blinks briefly, and then a series of 3–4 rapid clicks follow. This same behaviour happens even with no load connected to the output. Has anyone experienced something similar or have any idea what might be causing it? Any suggestions for diagnostics or next steps would be greatly appreciated. Thanks in advance! ---

Hi did you program it to the right grid code? It looks like it refuses grid ---

@fab10 What firmware version are you on as in the 510 release some changes were made as below. Your firmware does not seen to match the latest. ![image](https://europe1.discourse-cdn.com/victron/original/3X/8/5/859252e466bbcb6b2d0be2f76c37d0042cd75da2.png) ---

Are your AC In and AC Out Neutrals actually joined? (that’s what is required by that grid code) Any VE.Bus error codes appearing in the MultiPlus ‘Advanced’ details on the GX device? ---

no completely different circuits however just did a firmware update to v556 and its finally doing pass-through its night time now hoping AC coupling working again tomorrow doing the same BS today also have tried disabling charging batteries and it still just wants to do its own thing and charge batteries instead of exporting ![Screenshot from 2025-06-17 18-34-46](https://europe1.discourse-cdn.com/victron/original/3X/2/a/2a9413ad9c9f6e1cfafb529eb014a6e0dd074af4.png) just glad I finally learnt how to remotely configure without the laptop instead of pulling the mk3 in and out of the VenusOS and laptop .. ---

Thanks @Dean_Commodore that must’ve been my problem. No errors on the ve.bus but I didn’t have the neutrals joined (I assumed that N-bypass meant bypassed in the inverter). It seems to be working fine now. ---

interesting everyone else is telling me not to do that got a photo of what you did? , did you actually physically connect the neutrals of AC in and AC out ? the manuals provided did not really show much of anything so its hard to force an electrician to do anything else and the only pictures I have found do not show them bonded if anyone has a link to the correct wiring I am all ears ![Screenshot from 2025-06-20 11-23-14](https://europe1.discourse-cdn.com/victron/original/3X/b/e/be5bd7df2a4ff11250393929ee053970e24ccaad.png) ![Screenshot from 2025-06-20 11-16-44](https://europe1.discourse-cdn.com/victron/original/3X/6/7/67b6643fec7ae4e593d60e1b585ee51ab4462b04.png) no dots on the wire over laps showing a connection AC in and the AC outs seem to be separate ? ---
