Nite And Day Power was founded over 25 years ago to service the need for reliable emergency power services in the Bay area and Northern California. We sell, install, maintain, and service Uninterruptible Power Systems (UPS) and emergency back-up power generators that support critical datacom/telecom installations and industrial process control equipment. By working closely with the leaders in the industry (i.e. Eaton/Powerware, APC, Toshiba, GE, Onan, Kohler), we stay abreast of the latest technologies used in the UPS and generator industries.
