Actually the comment was meant for people like Glenn who live in areas where hurricanes prevail as there is a need for a generator and UPS that work with a generator. I have no need for a generator, but I thought that I would pass on that little titbit that I picked up in my research. However, the issue with the APC and Tripplite if I have understood the documentation correctly is to do with Line interactive UPS and not Online UPS which is what you may be using.

Actually the thing that put me off the APC was the lifespan of the batteries and no justifiable reason for the extra cost. More than one post said that they got better battery lifespan from the Eaton and when you consider the batteries are like 80% of the cost of the UPS, for the battery renewal schedule is of great importance. I am not saying that APC are bad, but I can't help wondering if you are paying a premium price for the logo mor than anything else to be honest. Anyway.
