There is a limit for maximum output power on the inverter, but since you are adding more strings to the inverter, it means that the inverter will hold onto maximum power generation for longer amounts of time. Essentially you are increasing the time for maximum operation resulting in overall more solar generation.

When calculating model for a hybrid system (ex. PV + BESS) does PVsyst consider the fact that the battery might charge from the grid? I have a feeling it does not but just want to make sure. And if that's the case, where can I find the button which allows me to turn on "Battery charging from the grid" option?
