Publication number: 20160190983Abstract: A notification apparatus is usable with a cooling system of a solar inverter and employs various environmental and operational parameters to calculate a cooling efficiency of the cooling system. The value of the cooling efficiency is employed to determine the potential for cooling system problems. The notification apparatus may employ a software-based model of the cooling system that outputs a predicted cooling efficiency. If the difference between the actual cooling efficiency and the predicted cooling efficiency is within a predetermined tolerance, the notification apparatus can instruct the performance of a relatively less extensive diagnostic operation to be performed on the cooling system at night. If the difference in cooling efficiencies is outside the tolerance, a relatively more extensive diagnostic operation can be performed. A rule-based diagnostic system employs the coolant pressures at the inlet and outlet of a radiator to generate one or more diagnoses of the cooling system.Type: ApplicationFiled: December 31, 2014Publication date: June 30, 2016Applicant: EATON CORPORATIONInventors: Meng Wang, Hassan Al-Atat, Anirudh Reddy Edla, Christopher Thompson
