The purpose of an inverter drive is to convert AC mains (single-phase or three-phase) into a smoothed DC (direct current) supply to operate a motor. Inverters also introduce the ability to control speeds, accel. [pdf]
Compared with other ways to store electricity, FES systems have long lifetimes (lasting decades with little or no maintenance; full-cycle lifetimes quoted for flywheels range from in excess of 10 , up to 10 , cycles of use), high (100–130 W·h/kg, or 360–500 kJ/kg), and large maximum power output. The (ratio of energy out per energy in) of flywheels, also known as round-trip efficiency, can be as high as 90%. Typical capacities range from 3 to 1. The speed control uses a current limiting means that safely limits the acceleration current to the motor for accelerating flywheel, and a rate controller that digitally switches the acceleration current on and off to maintain the desired steady state speed.

The overvoltage of the power supply means that the DC bus voltage exceeds the rated value because the power supply voltage is too high. Most of the inverters now have an input voltage of up to 460V, so the overvoltage caused by the power supply is extremely rare. [pdf]
[FAQS about How many volts is the inverter overvoltage ]
A DC surge protection device (SPD) protects your system from overvoltage due to lightning strikes or unusual high voltage spikes from the grid. In this article, I will talk about installing a surge protection device for solar panels. [pdf]
