Thank you for checking in with Captain PriceCheck! Based on the search results, it seems there aren't any listings directly for a 250KVA 3-phase generator. However, a few options that might interest you are: The 30KVA 3-phase generator for R223,999 could be a good high-power backup option to consider. It has the benefit of being water-cooled and includes an automatic transfer switch for seamless power switching. The Totai generator and welder for R27,499 is a more versatile multi-use machine. However, at only 5.5KVA, it may not meet your power needs. My database is still growing, so I apologize I couldn't find a perfect match. Please let me know if you need any other details as you research backup power solutions. I'm always happy to search further on your behalf.
