ACout2 in ESS mode

Hello,

I am aware ACout2 will only work when there is AC present on the input. What is not clear is if battery power will be used? The customer has some loads on ACout2 but in some instances wants to maximise the energy drawn from solar and the battery. I am not sure if it will just power these from the mains or not?

The question is will battery power be used when ACou2 is being used, not how to turn ACout2 on or off.

Ofcourse! The battery power will be used to supply the loads regardless the output used. Only behavior is different in case of grid failure or assistans settings

AC2 out is programmable as to when it will turn on/off using assistants

for multiplus and quattros, (NOT FOR MULTIPLUS II units)

so it would depend on what inverter you have

Thanks, I have used assistants so know how to use them. Just not what one is required for this scenario like you said?
