Energy storage batteries, particularly lithium-ion types, typically operate effectively within a temperature range of 20°C to 60°C. Beyond this range, significant performance degradation and potential safety risks arise.
A microgrid solar system is a localized energy network that uses solar panels as its primary power source, combined with battery storage and intelligent control systems, capable of operating independently from the main electrical grid when needed.
The most visible sign of a hotspot is a temperature increase, making infrared thermography the most direct detection method. On a sunny midday, maintenance personnel can scan the modules row by row using a thermal imaging camera.
