Product Description

Introduction
The VSPCS series energy storage bidirectional converter is a new type of bidirectional converter with completely independent intellectual property rights developed by Weiss. It adopts high-efficiency modular design, has excellent fault ride-through capability, and is convenient for optimized configuration, maintenance and replacement of energy storage batteries. The bidirectional converter has the functions of realizing the two-way dispatch of grid-connected electric energy, assisting the smooth grid-connection of new energy, and supporting the independent and stable operation of the microgrid.

Product Features
●Advanced parallel technology of voltage source without communication line, supporting unlimited parallel connection of multiple machines (quantity, model).
●Remote fault diagnosis and remote upgrade function.
●Support multi-source parallel machine, and can be directly networked with oil machine.
●Advanced droop control method, the average division of the voltage source parallel power can reach 99%.
●Support three-phase 100% unbalanced load operation.
●Support online seamless switching of parallel and off-grid operation modes.
●With short-circuit support and self-recovery function (when running off-grid).
●With active and reactive power real-time dispatchable and low voltage ride through functions (when connected to the grid).

●Adopt dual power supply redundant power supply mode to improve system reliability.
●Support multi-type load single or mixed access (resistive load, inductive load, capacitive load).
●With complete fault and operation log recording function, it can record high-resolution voltage and current waveforms when faults occur.
●Optimized hardware and software design, conversion efficiency can be as high as 97.5%.
●L series converter supports OV start, suitable for full-sail flow battery.
●20-year long life design.
