Solar and Battery + Charge Anytime - How to stop battery draining when Zappi charges EV?

Hi Peter

Agreed re the economics but would expect that an OVO supplied system utilising an OVO approved and managed Zappi and charge their anytime app it would be very simple to set up and manage. These questions / requirements will come with most installations. If it involves electrics this should undertaken at the OVO install ?!

Welcome to the Forum ​@Neilxxx, I hope you’re well.

I’ve added badges to your profile to display the kit you have. I can see ​@Peter E has given some great advice here (thanks Peter), and apologies that you have this issue.

I just wanted to share a fantastic guide that ​@Peter E wrote up about this issue, hope it helps you:

​@Neilxxx Given that home battery systems and charge points come with differing abilities you often end up with different solutions. With the correct placement of CT clamps from both systems and the correct setting up of both apps it is possible to have the EVSE wired anywhere in the system and the apps prevent the discharge of the home battery into the car. However, you need an installer familiar with that particular combination of tech and detailed knowledge of both systems (they should know the Zappi but not necessarily the home battery) and how they need to work together.

The owner will also have to understand how each app is set up and should either of the apps change (facilities added or removed) then you may end up with an undesirable result. This is because we have made systems too difficult to be easily understood either by the owner or the installer.

The guide I gave (thanks ​@Ben_OVO) is simple and foolproof and it has limitations but it seems to be the go-to solution for many people in that situation.
