An energy storage system (ESS) is a complex equipment that can control and store the electricity flows in the power system. The power source is an indispensable part of ESS. The most common power source used in ESS is solar energy.

Another critical component is an inverter. The inverter can convert DC to AC and feeds to the grid. Thus, the power can be used in household appliances. 

The core of the ESS is the battery. This component stores the incoming energy or electricity from the power system and discharge later when needed. A battery will have a maximum capacity and needs various times to charge fully.

The energy monitoring system acts as a sensor in the energy storage system, enabling users to visualize all the power flow through the ESS. More importantly, it knows how much energy is consumed from the grid, the battery information, and the consumption pattern. This system allows users to monitor the real-time performance of ESS through a mobile app. Any system failure will be detected instantaneously and reported to users.
