“EFOY Pro saves time!”

Previously, we were not able to guarantee a reliable power supply using only solar power. The effort to replace batteries is significant. With the EFOY Pro, we are not only sure that the system has power in any weather but we also save a lot of money by not laying power cables.

How Continuous Power Supply Keeps Your Business Running Smoothly

In an age where continuous power supply is essential for the smooth running of businesses, both large and small, it’s crucial to understand how this technology works and its benefits. Here we will discuss some key features of continuous power supply and explain why it’s such an essential part of modern business and industry.

The Importance of Power Reliability

Achieving high power reliability is essential for any business or industry. A continuous power supply system is vital to attaining power system reliability. A simple power system reliability definition is that it represents the probability that the system will perform its required function under stated conditions for a specific time interval. It is usually expressed as a percentage. For example, if a power system has annual reliability of 99%, it is expected to function correctly 99% of the time during that year. [1]

Many factors can affect power system reliability, such as:

  • Environmental conditions
  • Natural disasters
  • Operational errors
  • Maintenance issues
  • Equipment failures
  • A continuous power supply solution, also known as an uninterruptible power supply (UPS), can help mitigate some of these risks by providing a uninterruptible power supply that can take over in the event of a power outage. It can also help regulate the power supply to maintain a consistent level of power, even if there are fluctuations in the primary power source. [2]

    How Does Continuous Power Supply Work?

    A UPS system is designed to provide an uninterrupted power supply to a load. The system is typically made up of four main components:

  • A storage device
  • An inverter
  • A rectifier
  • A static bypass
  • The storage device is typically a bank of batteries that can provide power to the load in the event of a power outage. The inverter converts the DC power from the batteries into AC power that is compatible with the load. The rectifier changes the AC power back into DC power so it can be stored in the batteries. The static bypass allows the UPS to bypass any damaged components and continue supplying power to the load. [3]

    When UPS systems are used in industry, they are often connected to critical loads which must be supplied with power at all times. In the event of a power outage, the UPS solution will take over and provide power to the load until the power is restored.

    Types of Continuous Power Supply Systems

    There are three main types of UPS systems: online double conversion, line-interactive, and offline or standby.

    Online Double Conversion

    The online double conversion continuous power supply solution is the most reliable and efficient type of UPS. This system provides your equipment with a constant flow of clean, regulated power. It does this by converting incoming AC power to DC power and then converting it back to AC power using an inverter. The advantage of this type of system is that it provides clean, regulated energy at all times.


    The line-interactive UPS system is ideal for businesses that suffer from frequent power fluctuations but only rare power outages. This type of system uses a line-interactive UPS to regulate incoming AC power. It does this by monitoring the voltage and making adjustments as needed. The advantage of this type of system is that it’s less expensive than an online double-conversion UPS but still provides excellent protection against power fluctuations.

    Offline or Standby

    The offline or standby UPS system is the most basic and least expensive type of UPS and is used mainly to provide your equipment with power during an outage. It does this by switching from incoming AC power to DC power stored in batteries. The advantage of this type of system is that it’s less expensive than other types of UPS but still provides reliable back-up power in the event of a power outage. [4]

    Does Your Business Need Continuous Power Supply?

    If your business depends on electricity, as most do, implementing reliable power systems is an important consideration. UPS systems can protect your equipment from damage caused by power outages, power fluctuations, and harmonic distortion. The resulting benefits include:

  • Reliable data transmission: Continuous power supply helps to ensure that data is transmitted correctly and without interruption.
  • Reduced downtime: A UPS solution can help reduce the downtime experienced by your business in the event of a power outage.
  • Improved equipment lifespan: Continuous power supply can help to prolong the life of your equipment by protecting it from damage caused by power fluctuations and outages.
  • Increased productivity: Continuous power supply can help to increase productivity by ensuring that your equipment is always operational.
  • Enhanced safety: Continuous power supply can help to improve safety by providing back-up power for critical loads in the event of a power outage.
  • Reduced costs: Continuous power supply can help to reduce the costs associated with power outages, including lost revenue, damage to equipment, and downtime. [5] [6]
  • Which reliable power generator products does SFC Energy with EFOY Pro offer?

    SFC Energy with EFOY Pro offers an extensive range of reliable power products, such as the EFOY Pro 12000 Duo designed for applications requiring high energy levels. The EFOY & EFOY Pro Fuel Cells are excellent for various applications and provide reliable power generation for weeks or even months with no human intervention. [7] [8]
