My assessment is it is probably a small current being pushed by capacitance. I could understand the floating N-G might cause this in inverter mode but could not understand why inverter's bypass mode caused the glow, when direct grid did not. However the path from inverter's AC Out to breaker...

I did some voltage measurements, disconnected the neutral cable and left the line connected, switch off, between "neutral in" other locations: 1. When on inverter mode (no N-G bond/floating): - to LED frame screws: 120 V - to LED neutral: 120 V - to concrete: 20-30 V 2. When on bypass mode...

I am not sure it is relevant, because the glow persists when inverter is set on bypass mode and there is no voltage difference between N-G, I believe in that situation the inverter is not doing much, it is passing through the grids power (however my issue suggests the inverter or inverter...

I was using an incorrect multimeter in my first set of readings, I think I fixed that. The probes were connected to try and read what Amps were passing through, I just made a post about the results. "Connect brown and blue together and also connected to one leg of power. That would determine...

Switch is a simple mechanical switch See attached picture, if positive line is broken the glow remains, I believe that eliminates the switch not isolating being the cause?

I think the attached pictures fix my measuring technique. When run in series on Neutral getting 0.058 mA When run in series on Line getting 0.10 mA Last picture shows if I disconnect the positive the glow remains If I disconnect negative but connect positive, no glow Probably not important...

Just a quick reply: 115 V is Neutral to Ground, but no ground wire is coming into the lamp, roof is cement and conduit plastic so I am confident there is no grounding of the lamp, and current passing across N-G's 115V is not applicable to the glow. No glow when the circuit is on direct grid...

Only L and N wires, which makes me think it can't be current passing to Ground?

Attached are pictures of the LED and some wiring. The LED only has 2 wires coming in, Live and Neutral I re-tested things, pertinent points: - When circuit is connected to grid supply directly there is no glow - When connected to the inverter, in both inverter and bypass mode, there is a glow...

See pics, yes when glowing there is 0.09 Amps passing through

- Thailand - Inverter: MPP 4kW PIP-4048MS Inverter is on an old firmware without option #38 (for allowing N-G bonding when in inverter mode)

But what about when on bypass the LED still glows? In that situation there is no V difference between N-G?

Thanks for all the replies, I will run some more tests and list out a more detailed post later, but in reply to this question (system is 230 V): [When on inverter mode (no N-G bond)] - ground to neutral ~115 V - ground to line ~115 V - line to neutral ~230 V [When on bypass (N-G bond from main...

Thanks, I replied in the other post that it does not seem to be G-N bond because when on bypass a G-N bond exists but the glow remains. If I move the circuit back to direct grid supply (not through inverter) the glow goes away..

Apologies, this is a duplicate post, I stepped away from the issue for a few months and forgot I had already posted at: https://diysolarforum.com/threads/led-lights-ghosting-when-on-solar-inverter-but-not-when-on-grid-power.77888/
