Energy Storage System Solution
HNAC can supply the energy storage products that are included optical storage integrated machine, energy storage converter and box type energy storage:
1. Optical storage integrated machine: The optical storage integrated machine is a device that is connected to the photovoltaic array, the battery system and the grid (and/or load) to realize electric energy conversion. It can control the photovoltaic discharge process and the charging and discharging process of the battery. Carrying out AC-DC conversion, it can directly supply AC load without power grid.
2. Energy storage converter: In the electrochemistry energy storage system, which is a device that is connected between the battery system and the grid (and/or load) to realize the two-way conversion of electric energy. It can control the charging and discharging process of the battery, and carry out AC-DC conversion. It is also can directly supply power to AC load.
For the above two devices, small energy storage products can be applied to scenarios such as home power supply, field power supply, and communication base stations, and large and medium-sized energy storage products can be applied to scenarios such as generation-side energy storage, grid-side energy storage, and microgrid energy storage.
3. Box type energy storage: In the purpose of product promotion and application, four PCS standard products with container have been developed, four PCS booster integrated cabin standard products, and other PCS box-type energy storage products and box-type energy storage systems can be customized and developed. The energy storage system can be customized and designed according to the different needs of users. It can meet the requirements of different scenarios and different capacities such as peak shaving/frequency modulation, multi-power micro-grid system, and fast-cut backup power supply..
