Good Day All,

I have a Kodak H3.0 Solar Hybrid Inverter with 8 Solar Panels and a Pylontech US3000 Lithium Battery. It is currently grid-tied and has been working very well for the past year.

Of late, mainly at night when I'm dependent solely on CP, my Inverter will error with an error code: IGFOL-F. Looking up the description for this error in the manual, all it says is "Grid current tracking fail". What I want to know is what does this actually mean? Is my Inverter faulty?

Don't want to call in my electrician/installer only to be told that there's nothing wrong with the Inverter and that it's a problem external to the inverter.

I've searched the net and it appears that no-one else has ever experienced this problem.

Any advice/help is greatly appreciated.

Thanks

That inverter includes a CT clamp that was theoretically installed in your DB somewhere - I would guess that this error relates to an issue with the clamp as that is how the inverter will measure / track grid current. Just a guess though.

No idea what that means, maybe some intelligent people here with Matric know what this means @TheChamp

I honestly have no idea, but I can see it has something to do with settings, some settings can affect other settings and result in such errors.

If i were to guess I would start with the source priority settings, since it happens at night it could be that the inverter reverts to drawing power only from the battery because of low consumption and for some reason the inverter does not detect the AC current when it's drawing from the battery.

I would start by eliminating the battery from the sources and making the inverter only draw from solar or AC, or pick an option that only uses solar and AC or AC only when solar isn't available. See if the fault re-occurs.

It's just a wild theory since I don't have any experience on the Kodak inverters but I would bet money that the issue is on the inverter and not external.
 
IGBT = Insulated-Gate Bipolar Transistors, the high speed switch. High frequency inverters use them (vs MOSFETs) .

I suspect that something about the grid is not great, or it is being fed grid that is outside of its set parameters. Do you have logs for the grid? Take a look at them to see if you spot anything funny at the time that the error occurs.

Alternatively, its time to call in the Kodak expert, might have to adjust the latitude of some of the grid values, or put a power meter in for a few lights to have some data.

@Rkootknir, is that that Digital Meter box that was installed when the inverter was installed?

@TheChamp, thanks for this. Will go through the settings tonight and see if anything in the settings looks wrong

@RonSwanson, just need some clarification. When we say "grid" are we referring to CP grid or is that my internal grid within the house?

As for logs, unfortunately not. I use a web portal called PV Monitoring and the Logs section of it doesn't tell me anything useful

Was hoping to avoid calling the installer but if it has to be done, it has to be done.

Thanks

The Eskom grid.
 
@Belgarath22754 grid will always refer to Eskom supplied electricity, unless you in one of the many braai threads in which case it might refer to a "Rooster" and no its not a chicken unless the chicken is on the "Rooster" or visa versa, provided it is not a BBC.
 
Hi All,

Just thought I'd let you know my issue is finally solved. Turns out the fault wasn't on the Solar Panels, Inverter or the battery. Since my last post, decided to bypass the Inverter and only operate on Grid. That Friday night, power failure and have been off grid since. Only managed to get reconnect now. Turns out it was a feeder cable from the street pole to my meter that had busted. Took them 4 days to find the fault to fix it. Thanks to all for your replies and suggestions. Much appreciate it.
 
Probably been happening throughout the day but only noticed it at night when the battery would be on standby and I'd be completely reliant on grid
