So, a few days ago, I purchased a used 1500 VA APC Smart UPS from a shopkeeper for 12,000. Is that a reasonable price for this UPS or have I been ripped off? The exact model is SC1500ICH.
Coming to the main question, this UPS works fine, gives me 35 minutes backup for my PC (not under full load, just watching movies and stuff), but it doesn't charge off of a 2.4KVa generator that is only running a couple of fans and 5 energy savers. I turned off everything and the UPS was the only thing connected to the generator and it still would not charge. I asked around on the APC forums, and they told me to reduce the sensitivity setting on my UPS, and that then the UPS would charge off the generator.
The problem is that it needs a specific DB9 serial cable to communicate with the PC, and I have no idea where to find that. Someone on this site posted a pinout diagram:
Would this cable work for my UPS?
What do you guys recommend I should do? Sell this UPS off and get a MacGreen 1200VA one, or try to get this sensitivity thing working (if it will even help)?
