Performance Characteristics：
 Flexible and convenient | Efficient and intelligent |
| Standard rack-mounted modular design,flexible configuration,convenient maintenance,convenient expansion | The high-efficiency version adopts a single-stage DC/AC structure to improve system efficienc |
| DC/DC,DC/AC,STS different types of modules can be freely matched and adapted to local conditions. | DC/DC,DC/AC adopt three-level circuit design,high conversion efficiency |
| Three-phase three-wire/four-wire self-adaptation,three-phase voltage phase sequence self-adaptation,more flexible application. | When the power grid is powered off or fails,the STS module cuts off the fault circuit,and the system switches to off-grid power supply to improve reliability. |
| Wide voltage version DC/AC contains DC/DC inside,wide input range,more flexible selection and configuration of photovoltaic modules and energy storage batteries. | Advanced interleaved control technology,small ripple current,prolong battery life. |
| The micro-grid intelligent management system self-identifies the number and function of modules,integrates a variety of operating strategies and communication interfaces,unified scheduling,and intelligent management. | |
| Configuration recommendation | |
| Optical storage union,cutting peak filling valley,saving work frequency transformer.Microgrid multi-energy complementary power supply,configuration of industrial frequency transformer. | When the mains power fails or fails,the STS module automatically cuts off the fault ioop,and the optical storage system supplies power off the grid to ensure the reliability of power supply. |
| Uninterrupted power supply for critical loads,configuration of STS modules. |
