I use ChatGPT for work and other stuff but it wasn’t really getting it on this question.

Let us know if this resolves your issue.

thanks Mars and everyone who commented. I fixed it. As well as reading here I asked AI and that was useful too.

i was able to guess the password for the engineers menu on the inverter and found the option. It  had set itself to zero export somehow and I was able to correct this. Production was absolutely flying today and exported about 8KW to the grid on what was a mixed day in terms of sun and cloud.

So would I adjust the “export margin” in the Eddi menus to do that? Looking at it now it is indeed showing zero.

In the inverter your installer may have reset to zero or it has itself. That is the only real thing that can modulate the PV output.

Not sure about the Eddi, you will have to read the manual.

That needs to be reset. 

Also look at the CT clamps for diverter and inverter. Move the one for the diverter upstream of the inverter one. In theory the diverter should sense current availability and power immersion before the inverter cuts back power.

installed last year and all worked perfectly. I change my internet and in order to connect the battery/inverter/solar to my new network I had to get an engineer out. The apps I have just would not allow me to do it. 

he didn’t reconnect the Eddi to the WiFi. I did, and it only worked after powering the Eddi down and restarting it. 

since then, there has been zero water heater by the Eddi and zero export to the grid. 


instead, the solar fills the battery to 100% and then production just ramps down to the point where there is only the use of the house being produced. So in the afternoon I can have 100% filled battery, bright sun and the solar only seemingly producing 500w, less than 10% of its capacity. 

if I turn on the oven or kettle for example, production will shoot away up for that short period. 

the suppliers seem baffled but I think it is more of a case of disinterested. 

any advice? Could changing settings in the Eddi help to fix the problem?
