X22 Solar diversion draining my home battery

Hi all,

I have an X22 Three phase charger which is great, however I’m running into issues where it will sometimes draw charge from my home battery in peak periods (usually late afternoon/early evening).

I had logged a support case and they finally came to the conclusion that this was happening as I have net metering and my inverter will sometimes export a large amount of power on one of the phases in order to offset/balance the other phases.

The suggested solution was to disable “Solar diversion” for those times when the sun will be down, however I already have a complex schedule defined in the Evnex App (three different tariffs over 5 different periods for each week day and a single tier for weekends) so doing this would further complicate my set up as well as still not prevent this from happening during those early and later daylight periods where I may still want to charge (depending on the time year).

Is there a way to set the app to trigger “Solar diversion” charging when the Net power is above the threshold I have defined in the app (i.e. “Start charging when export is more than (kW)”), instead of when any of the three phases individually exceed the setting?

btw. I do have a low export limit as well unfortunately. I’m on three phase, but with a total export limit of 4.5kW. (i.e. not 4.5 per phase)
