moderately sized substation may require instantaneous current of 300 – 400 amps in order to perform its basic reliability and grid safety duty cycle. This high instantaneous current, often needed at or near the end of a discharge, drives the battery capacity sizing when applying IEEE 485 battery capacity sizing standards.

Inverter capacitor charging spark! | DIY Solar Power Forum
If you are using LiFePO4, these cells have such low internal resistance they can deliver a MASSIVE amount of instantaneous current. It is not unheard of to actually melt the capacitor leads as they are pretty thin and on initial charge the capacitors can take in a HUGE amount of current, more than the actual leads can handle.
What are the behaviors of capacitors and inductors at time t=0?
For an uncharged capacitor connected to ground the other pin (the side of the switch) is also at ground potential. At the instant you close the switch the current goes to ground, that''s what it sees. And the current is the same as when you would connect to ground without the capacitor: a short-circuit is a short-circuit.

18.5 Capacitors and Dielectrics
The top capacitor has no dielectric between its plates. The bottom capacitor has a dielectric between its plates. Because some electric-field lines terminate and start on polarization charges in the dielectric, the electric field is less strong in the capacitor. Thus, for the same charge, a capacitor stores less energy when it contains a ...

5.19: Charging a Capacitor Through a Resistor
But the energy lost by the battery is (QV). Let us hope that the remaining (frac{1}{2}QV) is heat generated in and dissipated by the resistor. The rate at which heat is generated by current in a resistor (see Chapter 4 Section 4.6) is (I^2R). In this case, according to the previous paragraph, the current at time (t) is
How does current flow in a circuit with a capacitor?
The displacement current flows from one plate to the other, through the dielectric whenever current flows into or out of the capacitor plates and has the exact same magnitude as the current flowing through the capacitor''s terminals. One might guess that this displacement current has no real effects other than to "conserve" current.

When power flows into an inductor, energy is stored in its magnetic field. When the current flowing through the inductor is increasing and di/dt becomes greater than zero, the instantaneous power in the circuit must also be greater than zero, ( P > 0 ) ie, positive which means that energy is being stored in the inductor.

Introduction to Capacitor
The capacitor is the basic electronic component that is used for storing, surge suppression and filtering. It is a widely used and important component in the family of electronics. Like resistor, capacitors are passive components to store an electric charge.The amount of charge that it can store depends on the distance between the plates.

The current through a capacitor is equal to the capacitance times the rate of change of the capacitor voltage with respect to time (i.e., its slope). That is, the value of the voltage is not important, but rather how quickly the voltage is changing. Given a fixed voltage, the capacitor current is zero and thus the capacitor behaves like an open.
