15 kVA Online UPS — questions
Anything not covered here, call us — most of it is faster to answer on the phone.
Why does a 15 kVA UPS have a three-phase input but a single-phase output?
Because the load is single phase but the draw is too large to take from one phase of the incoming supply. Rectifying from all three phases balances the load on your connection and keeps the incoming cable and protection sensibly sized, while the inverter still produces the single-phase supply your equipment expects.
240 V or 360 V battery bank on the 15 kVA?
The 360 V bank stores considerably more energy for the same amp-hour cell, so it is the choice where backup time matters. The 240 V bank is twenty cells against thirty, so it costs less and takes less floor space. Tell us the runtime you need and the answer follows from it.

Where we supply and attend
15 kVA Online UPS units are built at our Pune works and delivered, installed and commissioned across the city and the industrial belt around it.
Outside these areas we contract individually against distance, and we will tell you honestly if the response time you need is not one we can hold to. All areas served
Not sure this is the right size?
Send the load list. Sizing against inrush rather than running load is where most undersized installations go wrong, and it costs nothing to check.
