READ MOREThen we go inside the UPS and have a look. We still has the 230W but since it is now a 12V system, we need to reverse the conversion into amps again and get something like 230W 12V = 19A 230 W 12 V = 19 A. And then we divide the battery capacity with this current and get something like, (150∗2)Ah 19A = 15h ( 150 ∗ 2) A h 19 A = 15 h.
