Negative Revenue

[Jimmyrn85]

Good morning all, I have a newly installed system on the garage with a Fox H1 G2 5.0kw inverter. 7x 445w panels at the moment but there is plenty of scope for adding more down the line.

I have setup in the app my tariff, which is purchasing lecci from the grid at 0.239pence per kw/h.

For context, I have an existing "rent-a-roof" system which was installed before I purchased this house and the lease has 12 years to run, therefore I cannot be paid for any export I produce, that all goes to the "rent-a-roof" company. I just get to use any lecci I want. I will install a battery on the Fox system at some point.

So with that in mind, why do I get the odd days showing negative revenue? What is that? I would like it to show me for every kw/h produced by the new system that I've saved 23.9pence.

Your advice/thoughts would be appreciated!

can you post a screen shot of the energy flow page so I can confirm how your system is setup.
The short version is the inverter will be recording it's generation without any additional action.

Hi Will, this page?

So do you mean by that, the negative value could be the cost of just running the inverter on days when there is no sun?

Not that page, that is your "home" screen.

Swipe right to left, then scroll to bottom to see the energy graph.

Thanks, here is a screenshot of the month, and of the 27th day which had a negative revenue of 17pence.

You are welcome, I will let Dave or Will respond with better information than I can provide.
