Product description
Deming Power energy storage products and system solutions solve power supply problems in areas with no and weak electricity, and achieve smart power supply and demand allocation. This system is designed for three-phase energy storage system, which can realize the functions of On grid power generation, off-grid inversion, and city power reverse charging. If the power grid is disconnected, the storage system can automatically and seamlessly switch to off-grid operation mode to ensure uninterrupted power supply.
1)Power peaking and valley filling. Meet various needs of customers;
2)Smooth output power, improve the proportion of grid acceptance;
3) Ensure electricity safety;
Performance characteristics
(1)The 32-bit DSP (Digital Processor TI 2812) +ARM (Touch Screen Master Chip) platform is used for touch screen display and operation, which facilitates field operation and parameter setup. The core driver of DSP control and ARM realize peripheral functions such as display and communication to improve power reliability.
(2)Support RS485, WiFi, GPRS, Ethernet communication, satisfy customer remote monitoring and other functions; can display AC and DC side voltage, current, operation mode, operation status, fault information, and can upload related data to the Internet of Things platform through the communication interface, and can start and stop power supply, parameter settings and other operations through the computer or mobile phone;
(3)Adopt three-phase four-bridge arm structure, which can carry 100% unbalanced load;;
(4)Designed for smart grids and smart microgrids, accept grid dispatching, cut peaks and fill valleys;
(5)Meets the access of lead-acid accumulator, lithium power, super capacitor, vanadium battery and other different energy storage forms, and has a wide range of applications.
