How long will a 2kVA UPS last?

approximately 45 minutes
How to Calculate Backup time. Backup time of UPS (in hours) = [ Battery rating (in Ah) × Battery rating (in V) × Number of Batteries × Battery Efficiency ] / Load in Watts (W). Therefore, with a load of 500W, the 2kVA will last for 0.75168 hours ( approximately 45 minutes ).

How long will a 150 Ah battery last?

It also depends on the usage of the battery and the appliance load on it. You can expect your 150 Ah battery to last for around 3 hours on 400 watts bulb load if it is fully charged. If the load or appliance wattage is reduced the backup will improve.
