They're owned by Eaton, which is pretty standard for commercial protection and backup equipment. They used to be really big into commercial and industrial eletrical and service equipment. When I was young we were salvaging 30 y/o eaton disconnects, panels and so on because they were so good. Personally cyberpower commercial line is right behind Eaton. Cyberpower and Eaton offer replacement parts for old units and will even service them (they used to anyway). I can't say the same for triplite prosumer equipment. I got shafted on my 3 year old backups for replacement batteries. They pulled the same shit APC does. Sell a unit that is discontinued after the warranty period, then don't offer parts or service. Or in the case of APC replacement batteries cost nearly the same as a new unit. The answer is always the same. Save your money, buy used commercial grade shit.
