Max Power of a Photovoltaic System Batteries

[9999]

Hello everyone!
I have a quick question for you: someone could please tell me which is the average maximum power that a battery in a PV plant can "store"? In other words, which is the maximum SoC the generally I can achieve?

Thanks in advice,
AP

are you asking about an off the grid system? then is up to you how many batteries you stick in there, just make sure your solar array is big enough to properly charge them.

all depends on the amp hour rating of the battery, along with the details about the number of charging cycles possible at difference states of discharge, which you'd then use to determine that actual usable energy storage capacity in each battery.

ie a battery could do 10,000 cycles of 5% discharge, 5000 at 10% disgharge, 500 at 50% discharge etc.... numbers purely as an example, see manufacturers specs for actual numbers.
