How many hours can a 12000 BTU Air-con run on a KVA inverter system?

To determine how many hours a 12,000 BTU air conditioner can run on a KVA inverter system, you first need to convert BTUs to watts. A 12,000 BTU unit typically consumes around 1,200 watts. If your inverter system is, for example, 1 KVA (1,000 watts), it would not be able to power the air conditioner continuously, as the AC requires more power than the inverter can supply. Therefore, the air conditioner would run for a limited time, depending on the battery capacity of the inverter system and its efficiency.
