I have apc 9130 3000va ups(rack mount) i was using it with external batteries (6 * 12v = 72v) system with external charger because of high amh batteries it was working fine for 2 months now i am getting error "291 DC link imbalance" when ever battery voltage rise above 80v ups shut down with this error (72 volt system fully charged at 81v or 82v)
The 9130 is not an APC by Schneider Electric product. It is an Eaton-Powerware product.
yes it is sorry for that
