What is the difference between UPS and EPS?

Function:

• UPS: A UPS is designed to provide continuous power supply to connected devices in case of a power outage. It acts as a bridge between the main power source and the devices, ensuring a seamless transition without any interruption.
• EPS: An EPS, on the other hand, is primarily meant for emergency situations. It provides power only during critical moments when the main power supply fails, typically in scenarios where safety or life support systems need to remain operational.  In domestic homes EPS maybe used as part of a sloar panel and battery storage system to provide power to lights, boiler and internet router.

Capacity & Duration:

• UPS: UPS devices come in various sizes and capacities. They are commonly used for computers, servers, networking equipment, and other electronics. Depending on the capacity, a UPS can provide power for a few minutes to several hours, allowing users to save their work, shut down systems properly, or switch to an alternative power source.
• EPS: EPS devices are usually designed to power essential equipment during a power cut. They are typically built to provide power for a short period, usually minutes or hours, until the main power supply is restored or until a backup generator kicks in.

Design & Features:

• UPS: UPS devices often have built-in batteries that store power to be used during outages. They also include surge protection to safeguard connected devices from voltage fluctuations or electrical surges. Some advanced UPS models offer additional features like voltage regulation, power conditioning, or software monitoring.
• EPS: EPS devices can take different forms depending on the application. They can be standalone battery-powered units or integrated into solar panels and battery storage installations. EPS devices are designed to deliver power instantly when the main power fails, ensuring critical functions remain operational.

In summary, a UPS is a versatile device that provides backup power and protects connected devices from power interruptions, while an EPS is focused on emergency situations, providing power to essential equipment for a limited duration until normal power is restored.
