Anyone who has lived in Dhaka knows the feeling. Power goes, the fan slows down, and within minutes the room turns into an oven. Work stops, food starts warming, and if you picked the wrong backup system, none of that changes. You’re still stuck.
The good news is that getting the right home ips doesn’t require an engineering degree.
You just need to ask the right questions before you buy. IPS Bazar is Bangladesh’s No.1 solar and power backup supplier, carrying quality imported IPS units, batteries, and solar solutions for homes and small businesses, with actual expert support after the sale.
What a Home IPS Does
An IPS stores electricity in a battery and flips it into usable power for your fans, lights, and TV the moment the grid goes down.
While power is on, it charges quietly. When it cuts, the inverter inside takes over within about a second and keeps your chosen circuits running.
A UPS does the same thing but switches in milliseconds, which matters if you’re running a desktop computer or anything sensitive.
One second is fine for fans and tube lights. It’s not fine for a PC that restarts every time the power blinks. In Bangladesh, IPS units are what most households use for heavier loads and longer backup. A UPS is mostly for protecting equipment, not for running a whole flat.
How to Size It Right
You don’t need to keep the whole house running. You just need to decide which appliances really matter during a cut and add up their wattage.
Four LED lights at 10W each. Two ceiling fans at 80W each. One TV at 120W. That comes to 320 watts total. IPS units are rated in VA, not watts, so you divide by 0.8. That gives you 400 VA, and you’d pick the next standard size up, something like 600 VA, so you’re not running it at its limit.
A medium flat with several fans and lights usually needs 900 to 1200 VA. Larger homes or anyone planning to run a fridge need more. IPS Bazar carries units from 700 VA to 2800 VA, so there’s a size for most homes without paying for more than you need.
Backup time is a battery question, not an IPS question. Higher amp-hours mean longer backup. Decide how many hours you want, then work backwards to find the battery that supports your load for that long.
The Battery Is Half the System
Most people spend twenty minutes comparing IPS brands and five seconds picking a battery. That’s backwards. The battery decides how long your backup lasts and how soon you’ll be back at the shop buying a replacement.
Flat-plate or sealed lead-acid batteries are the cheapest option. They work, but they wear out faster, especially in homes where power cuts are long and frequent.
Tubular batteries are built for exactly this kind of use. They handle deep discharge better and last roughly 20 to 25 percent longer than flat-plate in real conditions. For most Bangladeshi homes, tubular is the sensible default.
Lithium batteries cost more upfront, but the math changes over time. A tubular battery under heavy use might last two to three years. A good lithium battery, specifically LiFePO4 with a proper battery management system, can last seven to ten years. They also charge faster and stop drawing power the second they’re full, which means lower electricity waste every single month. IPS Bazar stocks both tubular and lithium options, so you can weigh the upfront cost against how long you actually want the system to last.
Features Worth Paying Attention To
Pure sine wave output is the one feature that separates a good unit from a frustrating one. It runs your appliances cleanly. Square-wave inverters cause a faint hum in fans, extra heat in motors, and slow wear on electronics. Over time, that matters.
A front display showing load, battery level, and estimated backup time is more useful than it sounds. You stop guessing whether you’re close to overloading it, and you know exactly when it needs charging.
Protection features keep the unit alive. Overload cutoff, short-circuit protection, over-temperature shutdown, and deep discharge protection are all things you want built in. Without them, a single fault can take out the IPS and whatever was plugged into it.
Smart charging options, like multiple current settings, let you match the charge rate to your battery type. Lithium models handle this automatically and stop drawing power once they’re full.
Before you finalize anything, check the warranty and who backs it. A unit without real after-sales support is a risk. IPS Bazar works with authorized brands and handles warranty claims, which matters a lot when you’re two years in and something needs servicing.
The Mistake Most Buyers Make
They buy in a panic during heavy load-shedding and copy whatever the neighbour has. Wrong approach. Your load is different. Your backup hours might be different. A unit that works fine for one flat can overload and trip constantly in another.
Calculate your load. Size up with a little headroom. Pick the right battery type for your budget and how bad your area’s cuts actually are. Buy from someone who can help when something eventually goes wrong.
Do that, and you won’t need to think about this again for years.
