Reason seems to be the huge difference in quality for these capacitors. And more often than not, replacing caps actually solves the problem. Now it occurred to me that some devices just appear to live forever (knock on wood), where others fail in two or three years.
About Photovoltaic Energy StorageThe storage conditions of electrolytic capacitors are defined in the data sheet. These conditions are temperature between 5 C and 35 C with a humidity between 10% and 75%. The quality of the oxide layer can deteriorate during storage without externally applied
