So this UPS doesn't really owe me anything as I've had it for about 10 years through many sets of batteries.
I'm getting an overload error if there is a surge or powercut so I'm assuming we're looking at something serious as the batteries were only replaced about a year ago. Any ideas what might be causing the overload error as it even occurs if there is no load on the UPS?
I'm just running my home server and I don't have the budget for an expensive model. Any recommendations in the NZD 1-200 mark?
