Edge Span can be used as solar energy battery storage systems, but why must aluminum enclosures be used? We need to know that solar energy battery storage systems are generally deployed in remote outdoor areas, and these areas will face very complex environments. For example, high humidity in rainforests, sandstorms in deserts, strong sunlight, high temperature, etc. will bring great challenges to the stability of solar energy battery storage systems. If an IP65 or IP67 aluminum enclosure is used, because of its own characteristics, the environment has no effect on it. Therefore Edgeware advocates solar energy storage systems to use aluminum enclosures above IP65 level.
