Best IPS for Dhaka Office 2026 — Capacity and Cost Guide
Why Your Dhaka Office Needs a Reliable IPS
Power outages remain one of the biggest operational headaches for offices across Dhaka. With load shedding still a reality in 2026, a single disruption can shut down computers, servers, networking equipment, and air conditioning for hours. For businesses operating in areas like Gulshan, Banani, Motijheel, Uttara, or Dhanmondi, having the right IPS (Instant Power Supply) is not optional — it is a core business investment.
This guide breaks down exactly which IPS capacity your Dhaka office needs, how much it costs in 2026, and which models deliver the best value for commercial environments. Whether you run a 5-person startup or a 50-seat corporate office, the information below will help you make a confident purchase decision.
How to Calculate Your Office IPS Capacity
Before buying any IPS, you need to know your total office load. Most Dhaka offices use a mix of desktops, monitors, Wi-Fi routers, printers, LED lighting, and air conditioners. Here is a simple step-by-step method:
- List every device that needs backup power during a blackout.
- Note the wattage of each device (check the label on the power adapter or device back).
- Multiply by quantity if you have multiple units of the same device.
- Add 20% headroom for startup surges and future growth.
For example, a typical small office in Dhaka with 8 desktop computers (250W each), 8 monitors (30W each), a Wi-Fi router (15W), 10 LED lights (15W each), and a small printer (50W) needs roughly 2,665W — meaning a 3,500VA to 5,000VA IPS would be appropriate.
IPS Capacity Guide for Different Office Sizes in Dhaka
| Office Size | Typical Devices | Estimated Load | Recommended IPS | Backup Time (4-hour shift) |
|---|---|---|---|---|
| 1–3 people (home office / freelancer) | 1 laptop, 1 monitor, Wi-Fi router, 2 LED lights | 300–500W | 1,000VA (600W) | 2–3 hours |
| 4–8 people (small startup) | 4–8 desktops, monitors, router, lights, printer | 1,500–2,500W | 3,500VA–5,000VA (2,100–3,000W) | 1.5–2.5 hours |
| 10–20 people (mid-size office) | 10–20 desktops, monitors, 2 AC units, lights, server | 4,000–7,000W | 6,000VA–10,000VA (3,600–6,000W) | 1–2 hours |
| 20–50 people (corporate office) | Desktops, servers, multiple ACs, elevator backup | 8,000–15,000W | 10,000VA–20,000VA (6,000–12,000W) | 30 min–1.5 hours |
Best IPS Models for Dhaka Offices in 2026
Not every IPS is built for commercial environments. Office-grade IPS units need clean sine-wave output (to protect sensitive electronics), high surge tolerance, and long battery backup with lithium options. Here are the top recommendations:
Best for Small Offices (1–8 people): Luminous 3.5kVA–5kVA Range
Luminous remains the most widely trusted IPS brand in Bangladesh. Their 3.5kVA and 5kVA models offer pure sine-wave output, automatic voltage regulation (AVR), and compatibility with both tubular and lithium batteries. Price range in 2026: BDT 28,000–45,000 (without batteries).
Best for Mid-Size Offices (10–20 people): HiTHIUM Lithium IPS
HiTHIUM lithium IPS systems are designed for offices that need longer backup with lower maintenance. A lithium IPS charges faster (3–4 hours vs 8–10 for tubular), weighs less, and lasts 8–10 years compared to 3–4 years for lead-acid batteries. For a 10,000VA lithium IPS system: BDT 85,000–130,000 (complete with lithium battery bank).
Best for Corporate Offices (20–50 people): Three-Phase IPS Systems
Large offices typically use three-phase power. Brands like Luminous, Delta, and HiTHIUM offer three-phase IPS systems from 10kVA to 30kVA. These systems can be configured in parallel for extended runtime. Budget: BDT 200,000–500,000 depending on capacity and battery configuration.
Lithium vs Tubular Battery for Office IPS — Which Saves More?
This is the most common question from Dhaka office managers. Here is a clear comparison:
| Factor | Tubular Lead-Acid | LiFePO4 Lithium |
|---|---|---|
| Price (initial) | Lower (BDT 15,000–30,000) | Higher (BDT 40,000–80,000) |
| Lifespan | 3–4 years | 8–10 years |
| Maintenance | Regular water top-up needed | Zero maintenance |
| Charge Time | 8–10 hours | 3–4 hours |
| Backup Efficiency | 70–80% | 90–95% |
| Weight | Very heavy (60–80 kg per unit) | Lightweight (20–30 kg) |
| Total Cost Over 10 Years | BDT 60,000–120,000 (2–3 battery replacements) | BDT 40,000–80,000 (no replacement) |
For offices running 8+ hours a day, 5–6 days a week, lithium batteries pay for themselves within 2–3 years. The zero-maintenance factor alone saves BDT 5,000–10,000 per year in technician visits and water top-ups.
What Does an Office IPS Cost in Dhaka in 2026?

Key Features to Look for in an Office IPS
When evaluating IPS systems for your Dhaka office, prioritize these features:
- Pure sine-wave output: Essential for computers, servers, and networking equipment. Modified sine-wave can damage sensitive electronics over time.
- Automatic Voltage Regulation (AVR): Dhaka’s grid voltage fluctuates between 150V–270V. AVR stabilizes this to protect your equipment.
- Overload and short-circuit protection: Prevents damage from equipment faults.
- Cold-start capability: Lets you start the IPS even when there is no grid power — useful for critical servers.
- LCD/LED display: Shows real-time load percentage, battery level, and input/output voltage. Helps IT staff monitor power status.
- Parallel capability: Allows you to connect multiple IPS units for higher capacity or longer runtime as your office grows.

IPS Installation Tips for Dhaka Offices
Proper installation is critical for office IPS performance and safety:
- Dedicated electrical room or area: Install the IPS in a ventilated space away from dust and humidity. Dhaka summers are brutal — temperatures above 40°C reduce battery life significantly.
- Proper earthing: Ensure the IPS and all connected equipment share a common earth connection. Poor earthing causes voltage spikes that can damage electronics.
- Separate circuits: Connect critical equipment (servers, network switches) to the IPS, while non-essential loads (extra lights, fans) remain on grid power. This extends backup time.
- Battery placement: Keep batteries at floor level or on sturdy shelves. Tubular batteries are very heavy — make sure the surface can support the weight.
- Ventilation for lead-acid: If using tubular batteries, ensure the room has adequate airflow. Lead-acid batteries emit hydrogen gas during charging.
Frequently Asked Questions
How long does a 5kVA IPS last in a small Dhaka office?
A 5kVA IPS with a 400Ah tubular battery can power a small office (4–6 desktops, router, lights) for approximately 2–3 hours. With lithium batteries, the same setup provides 2.5–3.5 hours due to higher discharge efficiency. Actual runtime depends on the total connected load — heavier loads reduce backup time proportionally.
Can an IPS run air conditioners in a Dhaka office?
Yes, but only with sufficient capacity. A 1.5-ton split AC draws approximately 1,500–1,800W. You need at least a 5,000VA IPS with enough battery backup to run it. However, running ACs on battery backup drains power very quickly. Most offices run ACs on grid power only and use the IPS for computers, servers, and lights during outages.
Is lithium IPS worth the extra cost for an office?
For offices that operate 5–6 days a week, lithium IPS is almost always more cost-effective over 5+ years. The higher initial cost is offset by zero maintenance (no water top-ups), faster charging (3–4 hours vs 8–10), longer lifespan (8–10 years vs 3–4), and better discharge efficiency. Offices in Dhaka that run 8-hour shifts save an estimated BDT 30,000–50,000 over the lithium battery lifecycle compared to replacing tubular batteries multiple times.
How often should I service an office IPS in Bangladesh?
For tubular battery IPS systems, check water levels monthly and perform a full service every 6 months (clean terminals, check connections, test load capacity). Lithium IPS systems require no regular maintenance — just an annual inspection of connections and firmware updates if available. In Dhaka’s dusty environment, clean the IPS unit’s air vents every 3 months regardless of battery type.
What happens if the IPS overloads in an office?
A quality IPS has built-in overload protection that automatically shuts down the unit before damage occurs. When you exceed the IPS capacity (for example, by turning on an AC when the battery is low), the IPS will emit an alarm and disconnect the load. Reduce the load and restart. Repeated overloads shorten battery life and can damage the inverter circuitry. Always size your IPS with 20% more capacity than your actual load.
