Hello PVsyst Community, Thank you for your help in everything, I have a question regarding the battery percentage on the first day of simulation, is it DOD percentage ? is it a certain percentage? how can I manipulate the simulation to make cloudy day so there will not be any sun to charge the battery for the required Autonomy? how can I know the percentage of capacity in the battery in a specific point? The system is Stand-Alone
