Honestly, the cost of repair might exceed the cost of a new unit. We can likely get any parts needed to repair the unit, but might not be the most cost effective solution. Might want to price around for a replacement unit. If you need additional assitance, please contact us.

Remove all load.
Turn off UPS.
Start UPS.
If fail remains, check the fuses and battery.

A battery charger, a bypass ...
