How to Choose a UPS System: A Beginner’s Buyers Guide

Unexpected power outages are common throughout Sub-Saharan Africa, leaving critical systems and equipment vulnerable. An uninterrupted power supply (UPS) is a device that provides backup power when the main electrical supply fails.

Whether for industrial, commercial, or domestic use, this device ensures vital equipment continues running smoothly until the grid source is restored or a backup generator replaces it. For those looking to select the perfect UPS system, it’s essential to understand a few factors contributing to this decision. So, what do you need to know before you purchase this important piece of equipment?

Today, the experts at PacB Power Solutions will investigate these factors, providing novices and newcomers with a beginner’s guide before they invest in this useful alternative energy source.

 

Important Factors to Consider When Choosing a UPS

When selecting a UPS system, focus on factors that ensure your system meets your backup power requirements. These are a few critical points to consider:

  1. Power Capacity: These systems are rated by the power they can provide, usually in kilovolt-amperes (kVA) or watts (W). Your choice of kVA output must sustain the equipment load you need to keep running during an outage.
    To calculate your capacity needs, add up the power consumption of the devices that rely on the UPS for backup. Choose a system with a higher capacity than your requirement to avoid system overloading. For example, if you need to support servers, networking equipment, or industrial machinery, you’ll need a higher output system to ensure everything runs seamlessly when the grid fails.
  1. Runtime Duration: The system must provide time for safe shutdowns or a backup generator to come online. The runtime is essential, especially for sensitive equipment that may be damaged or information loss due to abrupt power loss.
    Systems are available in various models with different battery types and capacities. Depending on your needs, it should be able to support your equipment for enough time, whether only for a few minutes or several hours, until the main power source is restored, or a generator takes over.
  1. Battery Type and Maintenance: The type of battery directly affects the system’s efficiency and maintenance needs. Sealed lead-acid (SLA) and lithium-ion (Li-ion) are most common. SLA batteries are typically cheaper and more widely used on smaller systems but require more frequent maintenance. Conversely, Li-ion batteries offer longer lifecycles, are more compact, and require less maintenance, but tend to be more expensive.
    Understanding your budget and the maintenance required will help guide your decision on the best battery type. Regular maintenance, such as checking the health of the batteries, can prevent unnecessary downtime when power outages occur.
  1. Size and Form: UPS systems are available in many sizes and configurations to meet space and operational requirements. From smaller units for individual desktops to larger industrial models for critical systems, assessing the physical space available for installation is crucial.
    However, choosing the right size is important to avoid incorrect sizing. Over-sizing can increase upfront costs, while under-sizing could result in insufficient power to keep your equipment operational through the expected runtime duration.
  1. Efficiency and Energy Consumption: The system will recharge its batteries when grid power is operational, and choosing an efficient model can reduce utility costs. Modern systems are engineered to minimise energy wastage by recharging with higher efficiency. This efficiency is important for businesses where energy costs are a significant part of operational expenses.
    Research systems that are energy-efficient and feature eco-friendly designs. This can help ensure your business operates sustainably, particularly when using multiple UPS devices to protect against power outages.
  1. Scalability and Future Needs: As your power requirements evolve, so should your system. The scalability of the machine when choosing a system is an important consideration. Will your system accommodate the additional load if your business expands, or new equipment is added? Some systems allow for adding batteries or even scaling up the entire system.
    Choosing a system with expansion in mind can save money and even prevent the need for a complete overall. When selecting a system, always plan for future growth, especially in rapidly evolving industries like data centres, healthcare, and industrial manufacturing.
  1. Remote Monitoring and Management Features: Many modern units have advanced monitoring capabilities that remotely track the system’s “health,” battery charge levels, and other performance metrics.
    This is useful in large-scale industrial or commercial applications, where systems must be managed continually and simultaneously. Remote monitoring also provides early warning signs of potential issues, allowing for prompt maintenance before a failure occurs.
  2. Cost Considerations and Budgeting: The cost of a UPS system can vary significantly depending on capacity, battery type, and features. While tempting, choosing the most affordable option is not always wise. Lower-quality machines may result in higher maintenance costs or insufficient power when you need it most.
    Consider the long-term cost, including installation, maintenance, energy consumption, and future upgrades rather than just the initial purchase price. It’s worth investing in a quality system that ensures reliable performance and protection for your equipment or information.
  1. Compliance and Certifications: Ensure your system complies with local regulations and industry standards. Ask for certifications that indicate the product meets these strict safety and quality requirements. Compliance ensures your system performs effectively and safely in your environment.
  1. Manufacturer Reputation and Support: Research units from reputable manufacturers renowned for quality products and excellent customer service.
