How to use my Hanchu battery storage for home without it feeding back into the grid?

I have a newly installed system comprising Midea ASHP, a Hanchu ESS 9.4KW battery together with a solar array.

I have set the battery to charge from the grid on low tariff and to discharge at the time of Peak Tariff using the "user defined" option in the Hanchu app.

What is happening is that if my home is not drawing many KW in the discharge period the battery also discharges to the grid. I don't want this to happen if I can avoid it.

What i want to do is have it discharge into my home over the 3 hr high tariff period without sending anything to the grid. Can I set that up somehow in the Hanchu ESS app.

Currently work mode in the app is set to "User Defined" with a discharge period between 16:00 and 19:00. It charges on the low cost tariff between 02:00 and 05:00.( the charge setting is actually 02:00 to 16:00 to prevent it discharging early)

The other options in the app are; "

Self Consumption Mode" which isn't showing any timer options.

"Backup Energy Mode which isn't showing any timers and "Off-grid Mode which has no timers. How do I achieve my energy consumption goal of using the battery entirely for my home in a set time without feeding back to the grid and, in such a way that it depletes based on home demand over the whole high tariff period. Any thoughts on this would be gratefully received.

Thanks

You do not want to have discharge set at all, turn it off.

That is only for when you want to discharge to the grid !

 

The system will power your household load from the battery automatically except when your charging from the grid.
