Stop battery from charging

ThomasBaker

I've a growatt battery, solar panels and the gadget that heats your hot water from the solar panels as well.
Is there a way to stop the solar panels from charging the battery first and so just export to the grid. The reason I ask is for days like today when agile gets the biggest minus rates later in the day. I'm really looking to keep battery empty not the best later slots

I have the same problem.
I want to drain my battery in the morning at 7:00 but I don't want it to start charging until 11:00. Is there a setting that fixes this? Like grid first.

Mikael There isn't AFAIK on Growatt systems.

On GivEnergy inverters you can simply reduce the charge power down to 0.

yes. Growatt has the option "Grid first". It would be nice if you has this option too.

Grid first is basically just a forced discharge/export dump. Much different to simply reducing charge power to 0 and allowing battery to discharge based on load.
