Apologies if this has already been answered: Is it possible to have AC Out-2 on a Quattro run in an off grid situation?
AC Out-2 only is available when power is present on AC IN-1 or AC IN-2. During battery operation it will be disconnected.
The idea is to have "non-essential" items, geysers, pumps etc connected to AC Out-2 that need to be disconnected when weather is bad and battery SOC drops below say 30% and reconnected at 40% as example. A generator will also be connected and manually started to charge batteries when weather is bad (but please note, AC-out 2 should still work without the generator present).
To my knowledge by programming assistants it could be possible to do the above, it is just not 100% clear whether this is possible without AC In-1 or 2 available.
