Universal battery

In some cases we need to define a generic battery pack only by its voltage and capacity, independently of real components. This may be useful for example when just beginning a project, of for sizing optimization (batch mode).

In both Stand-Alone and Grid-Storage systems, you can always choose a "Universal" battery in the database. This may be either a Lead-Acid, or a Li-Ion (LFP) device.

You are just prompted for defining a nominal voltage and capacity. PVsyst will construct a pack, by an assembly of usual elementary blocks (12, 24 or 48V for lead-acid, 12.8, 25.6 or 51.2V for li-ion). Therefore the final voltage will not exactly match your requirement, depending on these basic voltages. But the capacity of the blocks may be adjusted without constraint.

Then PVsyst will construct these blocks with all necessary parameters, chosen at their default value. This allows to use the Universal batteries as any usual battery in the simulation.

You can open the battery block as a normal battery for just watching the specified parameters and behaviour. But you cannot modify them.
