Please see attached, - which setting to ensure that the only time the battery is used to supply loads is when there's no municipal supply... currently the PV supply power during the day to charge the battery & excess power to supply essential loads circuit connected to inverter...
I just had a 3kw Growatt inverter installed - according to the installer it may run microwave, air fryer, fridge, freezer etc but will run the battery charge down quicker... please note that all the above is for a worst case scenario... not all appliances on all at the same time
