A power supply is disclosed for an industrial control system or any system including a distributed power supply network. In embodiments, the power supply comprises: a battery module including a battery cell and a battery monitor configured to monitor the battery cell; and a self-hosted server operatively coupled with the battery module, the self-hosted server being configured to receive diagnostic information from the battery monitor and provide network access to the diagnostic information. In implementations, the diagnostics stored by the self-hosted server can be broadcast to or remotely accessed by enterprise control/monitoring systems, application control/monitoring systems, or other remote systems via a secured network (e.g., secured access cloud computing environment).
