Modular PCS spec.

XYH series Bi-directional storage Inverter is the key equipment for energy exchange between energy storage battery components and power grid. It can accept power grid dispatching instructions, realize charging and discharge management of energy storage battery, and realize power grid peak shaving / frequency modulation function. It can monitor the real-time characteristics of load and realize peak shaving and valley filling. At the same time, it can provide reactive power support, make up for voltage defects, control power quality and so on to ensure the stable operation of power grid system. It has the ability to resist short-term impact and can carry completely unbalanced load to realize smooth power supply.

The XYH-PCS / 500 or XYH-PCS / 630 Bi-directional storage Inverter supports two working modes: grid connected and off grid. The grid connected mode can be set to constant power (P / Q), constant DC voltage and constant DC current mode. The off grid mode can be set to VF source as voltage source, and supports online switching between off grid mode and grid connected mode (external hardware support is required). In the grid connected system, the P / Q mode is selected to realize the "peak cutting and valley filling" of power grid load when cooperating with the power grid dispatching system; When constant voltage mode is selected, it can be used as AFE DC voltage source to stabilize DC voltage; When the constant current mode is selected, it can be used as a charger to charge the energy storage battery.
