The newly launched "zero auxiliary source" solution is composed of three modules: "photovoltaic module, energy storage cabinet, optical storage converter". Among them, while the photovoltaic module receives sunlight and converts it into electricity, the energy storage cabinet can participate in the storage or release of electric energy according to real-time demand. The optical storage converter can convert the DC power of photovoltaic modules and energy storage cabinets into AC power for transmission to the power grid. The three modules cooperate efficiently to help realize the functions of power grid active support, power fluctuation suppression, peak regulation and so on.

The biggest highlight of the solution is the "zero auxiliary source". The energy storage cabinet used in this solution is equipped with the industry's first long-life high-temperature cell, and the system cycle life can reach 15,000 times. With high temperature resistant graphite anode material and special electrolyte, the energy storage cell still maintains good attenuation characteristics under conditions of more than 35 ° C, without cooling system and external auxiliary power supply, optimizing system performance and efficiency, achieving maintenance-free.

From the perspective of the working mode, the energy storage cabinet participates in the storage or release of electric energy according to the real-time demand, and the optical storage converter converts the direct current energy of the photovoltaic module and the energy storage cabinet into AC electrical energy for transmission to the grid, getting rid of the dependence of the traditional optical storage system on the cooling system and its auxiliary power supply.

In terms of technology, the three modules can achieve real-time linkage of light storage, increase the control response speed by 10 times, achieve millisecond power control, and increase the charge and discharge efficiency by 10%. The system uses high temperature cell technology to effectively improve the adaptability of the energy storage high temperature environment, without cooling, and free the energy storage battery's dependence on external auxiliary source power. The system is equipped with a battery cell with a cycle life of 15,000 times to achieve the same light storage life.

In terms of software, the system can also carry out real-time analysis of the light intensity and working scenarios, identify the photovoltaic and energy storage distribution needs in different environments, adapt to the maximum efficiency under the changing weather, and output power "zero" deviation.
