Battery backed up systems have a battery bank that is connected to an inverter.
What is an electrical emergency power.
An emergency power system is an independent source of electrical power that supports important electrical systems on loss of normal power supply.
Next option on the emergency electrical power food chain are battery backed up systems.
In the nuclear power plants diesel generators are the standard for emergency or standby electrical power supply.
These are not car batteries but deep cycle ones.
They are used for both aircraft startup and as an emergency source of power in the event of a generation or distribution system failure.
The inverter changes the 12v or 24v dc voltage to a usable 120 240v.
This is required by federal regulations codes and industrial standards.
Students are trained on the basics about the emergency diesel generators edg as the basis for the nuclear power plant workplace.
They are heavier more expensive and designed differently.
Homeowners are also installing smaller standby generators on their property especially if they are in rural areas where power restoration after a storm could take days or weeks.
