4 FAQs about Emergency energy storage system power supply solution

What is emergency power supply system (EPSS)?

Accreditation standards recommend CIs to have emergency power supply system (EPSS) in order to form a local microgrid network with backup resources (generation units/renewable resources) in case of sudden power blackouts of main grid supply.

What is emergency power supply & why is it important?

From hospitals to data centers, the need for a dependable emergency power supply is paramount in ensuring continuity, safety, and mitigating critical risks during unforeseen power outages.

What is an emergency power system?

Safety and Independence: Emergency power systems are often dedicated to supporting life safety systems, including emergency lighting for egress, fire pumps, sprinkler systems, and fire alarm systems, ensuring that these critical functions remain operational during a power outage.

What is stored-energy EPSS (sepss)?

Accreditation standards, such as NFPA 111, recommend stored-energy EPSS (SEPSS), which employ batteries/fuelcells/ultracapacitors as the main energy harvesting units along with inverter topology to assist in restoring of power to CI in the case of the grid failure . Briefly, these standards for CI recommend the following:
