Hi all,
I have a Cyberpower CP1500EPFCLCD which is failing on battery test (power cord detached). There are no errors on LCD screen, no issues reported on PowerPanel software. Not sure if this is linked or not but I suspect that this behavior came after a thunderstorm although the UPS was connected to another AVR.
I have checked most of the components (no sign of burned components, capacitors looks good), mosfet checked, relays checked and working, batteries are ok but still not switching to invert the 24v DC to 220 AC.
Any help or schematic (even better) is highly appreciated.
