Can I charge the battery only when the export limit is reached?

I'm going to exceed my export limit from time to time. I had thought that I might force export the battery during the morning peak, then only charge once the export limit was reached. But I can't find a way to do this... any ideas?

Thanks

[unknown] does the inverter automatically enforce the export limit? If so, simply turning off eco may be sufficient. Works for me to avoid solar clipping, by providing grid-first priority: it generateds AC up to the 5kW limit, and puts the rest in the battery.

ah OK that sounds good... but I can't see how to turn off ECO mode I thought my only options were forced charge / forced discharge ? (I don't seem to have a mode switch anywhere that I can find)

The inverter will automatically divert excess to the battery when the inverter limit is reached, if the battery can take it.

Even if you don't have a charge schedule set or ECO set to on.

If eco is on, it wlll send us much as possible to the battery, before sending any to the grid,

Nil Desperandum In the app and on the portal inverter/settings, eco mode on/off is the first configuration item.
In the remote control page, it's 'enable eco mode'

DD yeah I don't seem to have that. I I have timed charge / timed export / winter battery conditioning ... and that's it!

In fact I just noticed I can't even see an export limit line anymore??? It used to say 11.04kw which is correct but I can't find that now. Do you happen to know where that is?

wrighar yeah problem is battery would fill very quickly - hence want to export first then fill battery with excess (over export limit)

[unknown] oh... How strange. An oddity of 3-phase model.

Before I discovered the eco trick, what I used to do is continuously adjust the charging power via modbus, so it consumed just enough power to leave as much as possible for AC, without clipping, which a similar problem to what you're tackling. I should still have that (python) code lying around somewhere.

There is this: but I'm not sure it really does anything...

Nil Desperandum On a PC, Inverter tab, click Remote Control icon.

#13 EricIoW

Nil Desperandum Click the Remote Control Icon, not Settings. ECO ON/OFF is there.

EricIoW yeah I've tried that - nothing there for me ... see pic above

wrighar I don't have that ... see 2nd pic above

thanks for everyone's help here - very frustrating not to have these controls (or perhaps they are there somewhere and I'm being a numpty!)

[unknown] probably worth asking support if you're supposed to have an eco mode. Or rather, if you should be able to turn it off.

Move pointer to left, click My Inverter, move top right click Remote Control icon (if not there click 3 dots to show it) I then get page with ECO on/off

EricIoW I don't have those controls

Given the lack of control that I appear to have, I've decided to hand control to Octopus on the Intelligent Flux... see if they can do anything useful. Thanks for your thoughts.
