Choosing the Right battery Backup for Your Business

As a fellow small business owner, we understand that power outages and electrical issues can be a real concern. Investing in a battery backup system is a smart decision to protect your valuable equipment and minimize downtime. However, it can be confusing to navigate the various types of battery backups available. At Intechtel, we’re here to help you understand the differences between Line Interactive, PFC/Sinewave, and Online/Double Conversion battery backups, and guide you in choosing the best solution for your business.


Line Interactive Battery Backup

In simple terms, a Line Interactive battery backup is an affordable and efficient option suitable for most small businesses. This type of backup protects your equipment from power surges, voltage fluctuations, and brief power outages.


  • Cost-effective: A budget-friendly option for small businesses.
  • Automatic Voltage Regulation (AVR): Helps stabilize voltage fluctuations without switching to battery power, prolonging battery life.
  • Basic protection: Offers adequate protection against common power issues.


  • Limited power conditioning: May not be suitable for sensitive equipment or areas with frequent power issues.
  • Simulated sinewave output: Can cause issues with certain types of devices, like those with Active PFC power supplies.


PFC/Sinewave Battery Backup

PFC/Sinewave battery backups are designed to handle equipment with Active Power Factor Correction (PFC) power supplies, which are common in modern computers and servers. These backups deliver a cleaner, more stable power output compared to Line Interactive models, ensuring sensitive equipment runs smoothly.


  • Compatibility: Works well with devices that have Active PFC power supplies.
  • Pure sinewave output: Provides a consistent, clean power output, reducing the risk of equipment damage or malfunction.
  • Better power conditioning: Offers improved protection against power disturbances compared to Line Interactive models.


  • Higher cost: Pricier than Line Interactive backups but still relatively affordable for small businesses.
  • Not as robust as Online/Double Conversion backups in handling severe power issues.

Online/Double Conversion Battery Backup

Online/Double Conversion battery backups are the most advanced and reliable option, providing continuous, high-quality power to your equipment. These backups completely isolate your devices from the power source, eliminating the impact of power fluctuations and outages.


  • Superior power conditioning: Offers the highest level of protection against power issues, making it ideal for mission-critical equipment and areas with unstable power.
  • Zero transfer time: Instantly switches to battery power during an outage, ensuring continuous operation.
  • Pure sinewave output: Provides clean, stable power for sensitive devices.


  • Higher cost: More expensive than Line Interactive and PFC/Sinewave models.
  • Increased energy consumption: Can be less energy-efficient due to the continuous power conversion process.


Choosing the right battery backup for your small business depends on your equipment’s sensitivity, power supply type, and the stability of your local power grid.
