FoxESS Community - Owners & Installers Forum

Hello,
My solar panels have been producing during this sunny period in excess of the 3.68 Kh (i.e. 16 amps) export defined by my DNO G99 'fast track'. On doing so, I contacted my installer to apply a G100 restriction so that I am exporting not above 16 amps. They did something remotely, but now I am seeing on the FoxCloud app. my excess electricity is being added to my usage. So yesterday without the restriction my utilities was using 780 wh now today they are using 1.20 Kh. It seems the app. is now just taking the total solar energy generated and subtracting the 3.68 kh export and representing my usage as one minus the other rather than monitoring my usage. The usages now grows and falls proportional to the solar energy generated.

As result I have no clue what I am actually using, as my electricity meter is SMETS1 and I am using not electricity from the grid anyway. I also do not know what is the surplus I am generating above 3.68 kh. I assumed that the FloxCloud inverter would know how much energy I am genuinely using but in this set up no.

My question is has the installer applied the G100 restriction in the correct manner? I assumed that the inverter would do its job, but a utility on the export line would reduce the amp down to 16 amps. This just indicates that its used energy by my appliances which it is not. Is there any other way to achieve G100 restriction, so that I get reasonable indication of my true usage.

G100 is a control that states export can only be up to 16 amp unless a permit to export more is applied for. I am doing that.

You would really need to know what they have done, the usual way to throttle the inverter for G100 is to set the export limit to 3680 watts, in that way the inverter would be able to use all of the solar energy to charge the batteries and run the house load but export would be limited to 3.68kW after which the MPPT's would derate to maintain that.

If you can have a look at the website Analysis graph that shows solar, grid, battery usage - you should not ever see your grid export go above 3.68kw and as it approaches it the solar power will reduce.

Also just to check, are all the solar panels connected to the Fox inverter or is there a 2nd solar inverter installed.

Thanks Dave.
What you outlined is what I imagined they would do. The energy above the cap would still be used to power the battery or add another AC in this hot weather but no it’s added to my consumption in the app at least. I am awaiting their response as I sent an email with the same question.

At the moment I am flying blind on how much electricity the appliances are using.
