Discharge rates matter most during an outage! In an outage, your battery becomes your grid. With the Powerwall''s 5kW continuous discharge rate you''ll be able to keep most of your house up and running. The Powerwall''s ability to surge to 7.5kW, means you should be able to keep essential pumps and other inductive loads going too.
C-Rating – C-Rating is associated with charging or discharging a battery. C-Rate of discharge is a measure of the rate at which the battery is being discharged when compared to its rated capacity. A C/2 or 0.5C rate means that this particular discharge current will discharge the battery in 2 hours.

The data sheet will always list the continuous maximum constant discharge current (which typically will be equal to or greater than 1C) and sometimes there will be several figures stated over various periods of time, as well as the "pulse current" (which is sometimes incorrectly referred to as the surge, inrush or start-up current).
Standard discharge current is related with nominal/rated battery capacity (for example 2500mAh), and cycle count. If the battery is discharged with a higher current, the real available capacity will be smaller (it may be much smaller). Discharging the battery with a lower current will extend the real available capacity a little bit.
there is an inrush of current as the input capacitance is charged up to the battery voltage. Inrush is a transient event, which means it happens in a very short time, typically measured in milliseconds, and its peak current is only limited by a total resistance of the battery-inverter electrical circuit. This resistance is
