Definitely i will do.

Hi, Coulomb Thanks for your time, I have made further experiments , i have increase the load when load goes above 700W earth light turns off. So the earth light turns on only when load between 200w to 700w, below 200w and above 700w no issue. Its really very strange.

Hi, I found new issue , at night or when ever system shift on grid, Earth light on electricity meter turns on and strange thing is it happens only when load exceeds 200w, My solar system is 3kw. What could be the reason? Note:-My house has no earthing. Only phase and neutral wires are there.

Try to change inverter settings. Program 1= sbu Program 16= oso I faced same issue , my settings was 1.SOL and 16.OSO When i change settings to 1.SBU and 16.OSO reverse and earth light problem solved.

Battery voltage was 27v and pv was providing power to load only no sharing from battery but still inverter was in bypass mode.

I think SUB and SOL is the same.

My inverter is The Knox Argon 3kW VMII 4000. i don't want to use SBU option, i want to preserve battery for Ls

I have following three options . Utility first Solar first Sbu (solar. Battery. Utility ). And my settings is on SOL . solar first

Hi, I have install new 3kw system. Inverter knox. Grid bypass mode Always on , connected to grid even enough energy from pv. I switched off grid and have tested with 2000 watt load worked fine but when switched on grid , bypass mode on. Below is my settings. 1. Sol 2. 30A charging current 3. Fld battery type 12. 24ah back to utility 13. Full back to grid 16. OSO Battery charging 26. 28.2ah Bulk charging 27. 27ah float charging 29. 21ah cut-off voltage Thanks
