Offline UPS – The Basic Backup

An Offline UPS, also known as a standby UPS, is the most budget-friendly entry-level option. It provides simple battery backup for basic devices and home setups.

How it Works:
Under normal conditions, power flows directly from the grid. When an outage occurs, the UPS switches to its internal battery within milliseconds to keep your devices powered.

Best For:

• Single workstations, laptops, or home offices
• Non-critical applications where short interruptions are acceptable

Advantages:

• Most affordable UPS option
• Energy efficient with low operating costs
• Compact and easy to install

Limitations:

• Only protects against blackouts; no voltage regulation
• Transfer time (2–10ms) can affect sensitive equipment
• Not suitable for mission-critical business systems

Line-Interactive UPS 

Line-Interactive UPS is the most popular choice among small and medium-sized businesses in Kenya. It offers a strong balance between cost and performance—ideal for environments with frequent voltage fluctuations.

How it Works:
This UPS features Automatic Voltage Regulation (AVR), which stabilizes incoming power without switching to battery mode. It instantly corrects minor sags and surges, protecting your devices while extending battery life.

Best For:

• Small offices, retail shops, and professional firms
• Equipment such as servers, POS systems, routers, and networking devices

Advantages:

• AVR ensures clean, stable power during frequent voltage changes
• Extended battery lifespan since minor fluctuations don’t trigger battery use
• Excellent protection at a reasonable price

Limitations:

• Slight transfer time (2–4ms) during full blackouts
• Doesn’t completely isolate devices from grid noise

Online (Double-Conversion) UPS

Online UPS provides the highest level of power protection available. It’s designed for critical operations that cannot afford even a moment of downtime.

How it Works:
This UPS uses double-conversion technology—incoming AC power is converted to DC and then back to AC—delivering perfectly regulated, clean power at all times. Your equipment always runs on conditioned power with zero transfer time during an outage.

Best For:

• Data centers, hospitals, and financial institutions
• Businesses where even milliseconds of downtime can cause data loss or financial damage

Advantages:

• Zero transfer time during power failures
• Provides pure, stable power 24/7
• Shields equipment from all power issues including surges, sags, frequency shifts, and outages

Limitations:

• Higher initial and operating costs
• Generates more heat, requiring proper cooling and ventilation
