The block diagram below is for a simple use of a solar array in conjunction with a battery, in a battery tied bus format. The diagram is simple and straightforward excepting the capacitor configuration.
One possible use of this configuration (usually) is to create a specific value of non standard capacitance using standard capacitors. This is clearly not the case as they are all equal and the equivalent capacitance is simply 100uF.
The configuration looks like it is acting as a filter in case of any sudden spikes in voltage, is this why it exists?
Could this configuration exist as some sort of redundancy?
