Hi Guys
As discussed… damaged UPS is costing us approximately:
1500 x 2 battery = 3000 per month
3000 x 12 = 36,000 In 1 year to replace batteries.
The more UPS we buy the more this cost will be.
This is bleeding money and it needs to stop with a better and more cost effective solution.
The solution is to move to IPS – but first I need to see the economics of this. Lets fill in the information for this table to help me decide on this please.
Assuming that an IPS battery system will last 3 years.

ok so i can see the difference here, the online UPS basically has more capacity with a lower time frame -thats why its sutiable for our needs.
whereas an IPS is low capacity for longer times.
pricing for online UPS and IPS seem very similar.
Now my question is...
for the online UPS, the descriptions emphasize on "battery" - this suggests to me there is a battery replacing problem - same as the UPS we ahve now... costing us a lot long term.
we are trying to eliminate this yearly 36k cost.
what is the battery replacement cost on these - and what guarantees are tehre? i.e. 2 year battery guarantee? and how long is a battery pack expexted to last before needing replacement?
Lets discover this to ensure we will get the cost saving we are trying to achieve as well as stable backup with less hassle of running many smaller UPS.
A 600VA IPS has a total load capacity of 500w while a 1200VA will have around 1000w load capacity,
A server typically uses around 300-350 watts and the HD monitors usually take 40 watts. So a server with 4 monitors will need a 500w IPS.
Here are a couple of examples of Online UPS found online in BD. Both these are 3KVA - around 2700 watts. Backup time 15-20 mins at full load. Should be able to handle 5 server and 20 monitors smoothly. It has 6 batteries.

Ok this is critical information for us to learn Ross.
so we have 2 other options to think about:
a. with an IPS like your home one - how many servers can we support? using the load calculation? im wondering if that works out better than running our servers on UPS modules we have.
b. the online UPS which you are looking into already.
lets get an update on the above 2 points as soon as you have something.
Hi Rob,
I researched this, but the IPS option will not work for us. Someone from the IPS office visited the office for a survey and then they quoted based on the total load we have.
The total load in our office is between 4500-5000 watts. The standard backup time of an IPS is 2 hours at full load. A 4500-watt IPS will cost us around 170k.
I talked about less backup time with more load—i.e. If we want 20 minutes of backup, can we buy a lower-capacity IPS? The simple answer is no. The IPS machine has a limit on how much load you can put on it, which is up to a maximum of 20% over its total limit. so to support a 4500+ load, we need to have at least a 4000-watt IPS. If we put more than 20% load, the machine will fail to support and we will lose warranty.
So it appears too expensive to me. They have suggested that we try online UPS which will probably be a bit cheaper than IPS. But this company doesn't sell Online UPS. I haven't found a reliable supplier for this in Sylhet yet but I am still searching.
