This scheme is applicable to the distribution system composed of photovoltaic, energy storage, power load and power grid(generator).
The application of the system in the power grid mainly includes the following scenarios:
Peak shaving and valley filling: by charging and storing energy at valley time and discharging energy at peak time, the electricity cost of customers can be reduced and the electricity charge at the power consumption end can be saved for customers.
Demand response: when the short-term power consumption is greater than the transformer capacity, the energy storage system will discharge rapidly to meet the load power demand
Dynamic capacity increase: energy storage equipment is used to replace the capacity of transformer in peak period to help customers reduce and reduce the expansion cycle and cost of transformer investment.

Off grid standby power supply: when the power supply of the power grid is interrupted, provide uninterrupted short-term power supply for important loads to reduce the economic losses caused by sudden power failure of loads.
The solar generation is given priority to the user's load to achieve the maximum economic operation, and the excess energy is stored in the daytime; 
When the photovoltaic power generation does not meet the load use, the load is powered by photovoltaic + energy storage; If the photovoltaic + energy storage does not fully meet the use of the load,it will be introduced by the mains to provide reliable power supply for the load; When the solar is redundant and the energy storage battery is full, and the photovoltaic surplus power is sale to grid.

The installation and use of energy storage systems have a big security risk , that is why we offer a 360° guarantee on solar power on/off grid system.

There are too many solar systems with different configurations in the market. Some companies design the configuration at random in order to make it good prices. Our company is based on 15 years installation and maintenance experience, in the case of protecting the solar power system life to make the configuration that meets the requirements of most customers.
