FoxEss Cloud - Interpretation

[4noxx]

Hello

Here is a screenshot of our system from the cloud.

-> PV: 8.867KW
<- GRID: 8,535 KW

So, current yield 8,867KW, feed-in 8,535 KW Is this interpreted correctly

That shows your PV generating 8.867kW and of that you are exporting 8.535kW to the grid.

It looks like a solar only inverter (S/T/G series) which isn't capable of showing the house load (unless you fit an optional meter)

this is my model:
FOX ESS T10-G3 10 kW

you sad -> optional meter

can u explain this? is this a hardware-addon for the T10-G3?

thx

There is an optional meter facility using either a Chint or Eastron 3 phase meter connected in-line or with CT clamps.

It is intended to be used for export limit control where the inverter limits it's output should an export limit be exceeded - but it does provide you with extra information such as real time house load power, grid consumption and export - but unlike with a hybrid inverter these are not available as statistics i.e. you can see a graph of power for each day, but you cannot see a daily/weekly/monthly statistic to say today's house consumption was 12kWh.

you mean a device like this:

?

can anyone connect it or does the specialist have to do it?

I can’t see the model number on the page but that looks like it a DTSU666, it has to be wired in-line to measure power so it would need a qualified electrician to do it - there is also a CT clamp version of this meter that uses CT (current transducer) clamps to detect power rather than being directly wired and these are more easily installed but costs over twice as much.

The meter is then connected to the inverter by a single twisted pair cable and into the meter connector of the inverter - these are not dangerous voltages but you would need to have some practical experience of wiring to complete the task.
Once installed the meter needs to be enabled in the inverter settings, that is easy enough and all of this is shown in the user manual.
