In practical applications of the integrated solar energy storage system, most power stations will divide the load into critical load and non-critical load, because for users of these power stations, the power consumption requirements of critical loads are higher, such as database stations or special electrical equipment, on the contrary, the electricity demand of non-critical loads is relatively low, Distinctive treatment for critical and non-critical loads can greatly reduce the capital investment of the power station. However, many users hope that the clean energy from the sun can be used for both critical loads and non-critical loads, so that renewable energy be fully utilized, and also the cost of grid electricity can be reduced. In order to fulfill these user demands, ATESS has proposed a solution to add a smart meter to the energy storage system.

The preheating of the electric vehicle refers to the use of the external power supply provided by the charger or the power supply inside the car battery to heat the power battery with various heating methods before starting the car, so that it reaches the optimal discharge working temperature, and then start the car. It is a warm-up before starting an electric car.

As one of the largest country in Africa, Mali’s electricity system encompasses a national grid that is owned and operated by Energie du Mali SA (EDM SA) which supplies 35 towns, including its capital city Bamako.
Hydropower and thermal power stations are the main energy generation sources at the national level in Mali. Although hybrid (solar/diesel) and small-scale decentralized solar PV systems have been increasingly installed since 2011, the share of renewable energy still remains low in the country. The average consumption is also characterized by a strong disparity between rural and urban areas. Urban population has around 80% higher access to electricity than rural population. People in the rural areas are still suffering from poor power supply.

When designing an energy storage system, the motor load is always a headache due to its large starting current. Sometimes it could be up to 8 times the rated current. To ensure the system's normal operation, The only solution is to choose a bigger power of inverter , and the system cost thus increases.
