Product Overview
The STD PCS1 series single stage energy storage converters are mainly used in the field of industrial and commercial energy storage. The devices mainly consist of AC distribution, transformers, energy storage AC/DC modules, monitoring systems, etc. By paralleling DC/AC modules, systems with different currents and powers can be formed. It can be widely used in large industrial and commercial areas such as industrial parks, community business districts, and commercial complexes with high energy consumption, providing assistance for comprehensive energy services.。
2、System topology
3、Performance characteristics
1）Adopting a modular parallel design concept, providing N+1 redundancy, improving system stability, and facilitating installation and maintenance for easy expansion.
2）It can adapt to various batteries and achieve different charging and discharging strategies for different batteries.
3）Energy scheduling can be regulated, and users can change the charging and discharging logic based on the electricity policies of different time periods in their respective regions.
4）The power factor can be adjusted arbitrarily to achieve independent control of active and reactive power, meeting different load requirements.
5）Supports grid connected and off grid operation, and can achieve automatic and seamless switching between grid connected and off grid states, ensuring the continuity of load power supply.
6）It can achieve constant voltage, constant current, and constant power charging and discharging control.
7）Friendly human-machine operation interface, convenient and practical operation, and with remote data transmission function in the background.
