Fox Battery will not Force Charge as the same time as Hypervolt EV Charger.

We’ve had our Fox system (KH7 and EP11) since October last year and had a Hypervolt Home Pro 3 Charger installed on Friday. Last night the battery did not fully charge as it did not start charging until the EV had completed which was several hours late according to the force charge window that we have set.
Is this expected and is there anyway to configure the systems so that both can charge at once please? We have a 100amp fuse on our mains supply.
Thanks

You will need your K series inverter firmware updated and the import restrictions set correctly. I show these new settings in this video.
Ignore the main topic about grid pressure setting, the settings you want to check with your installer are GridChargeCurrentLimited & ImportLimitCurrent settings.

OK great thanks. My ImportLimitCurrent was set to 50.0 and more worrying the ExportLimitCurrent was set to 150.0 (not quite sure how as the range is 2-100). I'm waiting for Fox to respond but have changes both to 95.0 to match your video.

On a related theme, when my EV charger was installed they have wired it so that it now drains the EP11 battery when IOG schedules peak rate charging windows and the EP11 isn't set to Force charge. The installer said he wasn't trained in solar and so could not add it as a separate circuit before the main house and solar circuit, i.e. straight after the tails coming out of the meter in the attached photo, but that should be simple shouldn't it?

Yes, a henley block on the tail straight after meter where the white CT clamp is.
I must admit I wouldn’t have wired any of it the way it is - so just to confirm i’m reading it right, bottom left is the feed to the EV charger, bottom right is the solar inverter and the feed through the 100A double pole switch through the backboard is going to the house consumer unit ?
