Battery set up question

Hi, sorry super new to this

How do I set up the battery to only charge from the panels and only supply the house?
I don't currently want to send anything to the grid nor charge from the grid

Rhoneyman welcome to the forum.

That should be the default behaviour. Note, however, that you can't avoid a few watts in/out of the grid - inverter takes a small amount of time to respond to changes in consumption, and until it catches up, grid provides the backup.

(And you can't avoid exporting if solar exceeds max charging rate of batteries, or once batteries get full.)

if you dont set a forced charge then your battery won’t charge from the grid. Eco mode is what you want, this will charge the battery from solar and discharge it to the house when your home needs it.

Unfortunately you can’t absolutely stop export to the grid. Once the battery is full any excess solar above your house demand will be exported, but that’s when you can put the washing on, etc to reduce the export
