The Complete Guide to Battery Capacity
Solar battery capacity refers to the amount of electricity that can be stored in a battery storage system. Storage capacity is typically measured in ampere-hours (Ah), watt-hours (Wh), or kilowatt-hours (kWh). The greater the solar battery capacity, the more electricity it can store. A high-capacity battery is particularly useful for homes that

Relation between C-rate and power of a battery
5MW (power) 5 MWh (capacity) 5MW/10 MWh. So the definition of the c-rate is: A C-rate is a measure of the rate at which a battery is discharged relative to its maximum capacity. A 1C rate means that the discharge current will discharge the entire battery in 1 hour. So for the second storage, a 1C shouldn''t be possible?
