I was a happy man till the Friday powercut recently started again. and now due to covid power cut problems are increasing as fixing takes time for the power company.
so decided to pull the trigger and get a Sinewave UPS Inverter. Now The requirement are as below:
1) 3 x fans.
2) 3 x 15w bulbs.
3) My Battle Station (1000watt smps) with 2 x 2k monitor.
4) My Secondary System (750wattt currently or 850watt in future) with 4x 1080p monitors.
5) Wifi router.

Backup required : min 8hrs and max 12hrs backup.
Got a quote of a 4kva Sinewave UPS Inverter with 4 x 150mAh Excit batteries costing around 80K.
Will this do or I should go for a 5 / 5.5kva Sinewave UPS Inverter.
also if things go out of budget, can get half battery now and half next month and have no issue ? i.e. for e.g 2 batteries now and 2 next month :p also no looking for a solar solution as I say in a rented flat, in future solar definately so this can also be used with that setup, right ?

These batteries will work in a normal setup too, but would require a special inverter though. If these batteries suit your budget, you can definitely go on with them because these have around 2000 charge cycles and also very safe and smaller in size compared to the Lithium-Ion and Lead-Acid batteries.

Do share the brand/model of an inverter that can serve as a UPS

I am afraid i can't suggest you an inverter since i am not an expert in LiFePo4 inverters but do check out the Loomsolar website and sellers on indiamart. Also do note that these batteries are more of a DIY thing since no mainstream brand currently offers a ready made battery packs like 12v 200Ah. Only 3.2V 100Ah cells are sold and you have to combine 4 cells to get a 12v 100Ah pack.

Well, you can't get half batteries now and half later because a 4kVA inverter will run on 48V and will need 4 batteries to run. You can reduce the capacity of the batteries but then your runtime will suffer.
Get any of the Luminous Cruze + models based on your requirements. You can calculate sizing by using one of the many calculators available online and a good Exide battery. Also search the forum. There has been a lot of discussion on batteries and inverters in the past few years.

Loomsolar gave me a quotation of around 2 lacs for 4kva battery and 5kva inverter. kinda expensive when I cannot even install a solar right now. they did said that I can use it without solar but still. its EXPENSIVE as of now :woot:
