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 and model).
● Supports multi-source paralleling, and can be directly networked with diesel engines.
● Advanced droop control method, the average division of power in parallel with voltage sources 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).
● It has real-time dispatchable active and reactive power and low voltage ride through functions (when connected to the grid).

● Adopt dual power supply redundant power supply mode to improve system reliability.
● Support multiple types of loads individually or mixed access (resistive load, inductive load, capacitive load).
● It has complete fault and operation log recording function, which can record high-resolution voltage and current waveforms during faults.
● Optimized hardware and software design, conversion efficiency can be as high as 98.7%.
● The DC side can be connected to photovoltaic modules, and it also supports parallel connection of multiple voltage sources, which can be used as a black start power supply for off-grid photovoltaic power plants under low temperature and no storage.
● 20-year long life design.
