New Fox Battery & Hybrid Inverter installed over existing PV & Inverter

[DanielSP]

Hi All, good evening!

Sorry if I say something dumb, but my knowledge is close to 0.

I have just got a new Fox ESS Battery EP12 and Fox Inverter H1-5.0-E-G2-WL installed over an existing PV system 3.2kW with a Fox Inverter S3000-G2 and the values in the app don't make sense to me. The installers came today again, but it still showing odd values. Just to make it clear, the only PVs in the system are the original ones wired to the S3000-G2 inverter.

The origjnal inverter is in the loft and the new inverter + battery in the garage. In my app I can see both inverters and the battery. But there is a Gen Load information over the Solar that I'm not sure what it is.

Can someone PLEASE help me figure out and maybe I can share with the installers?

Gen load shown in the app for me is from our original small solar system and a newer and larger solar system was wired directly to the new hybrid inverter and it reports separately as solar.

If it's showing at night like it seems to be, it could be the CT clamp monitoring it is connected to the wrong wire or is installed backwards.

Also you might want to delete the images you posted as your email address is showing and LLM AI is more than capable of collecting addresses that way to spam you later.

Hi, the only PVs in the system are the original ones wired to the S300-G2 inverter in the loft. The new installation is only battery and inverter.

In that case it looks like you have 2 CT clamps on something, maybe the Gen load is the house load and was installed incorrectly and I have no idea what 1st would be monitoring as 44W used by the house is very wrong too.

Hi,

Yes, there are 2 CT clamps on the same wire, they say one for the original inverter and 1 for the new inverter. There is also another CT clamp outside near the meter.

The new inverter doesn't need a CT clamp to know what it's doing.

You might need to switch the CT clamp going to the meter as it shouldn't be gen load as that should be for another solar system so the inverter is probably confused by the inputs.
