EV Charger Draining Battery - Incorrect Install?

[macgyverfan]

Currently my solar is tied into the grid in the same distribution box as my charger is connected, sharing the cables from a henley block between the meter and consumer unit. Where the solar CT clamp is currently, the inverter sees the EV charger current resulting in my house battery being depleted.

The solar installer suggested moving the solar CT clamp to the leg between the henley block and the consumer unit but that reported an inverse of the solar generated and my battery power wasn't used for anything.

Wondering if the solar tie in should be through a separate block as this proposed image below. Thoughts?

I would prefer a hardware solution rather than trying to use mode scheduler as I want to charge my solar battery overnight as well as charging my car overnight once a week or so.

Yes agree a hardware solution is much better and it doesn't drive you mad when you forget to set a charge period.

You're nearly there, you need to move the solar CT so that the solar sees the load plus the effect it is having with export etc.. - and you need the EV and EV CT clamp in front of all of it so that the inverter doesn't see it's usage - so wire it like this ->

Thanks Dave.

I'll run this by the installers and see if they can get it sorted
