Product Overview

The YZ Series PCS & Step-Up Integrated Cabin integrates power conversion system and step-up transformer, with three power models: YZ1250-ZC, YZ2500-ZC, YZ3000-ZC, delivered as an all-in-one container unit.

The container is pre-assembled with PCS modules, step-up transformer, power distribution, cooling and monitoring communication systems, fully tested before delivery. On-site installation only requires connection with battery clusters and 10~35kV medium voltage grid, saving land space and construction time. Compatible with 1000~1500V high-voltage battery systems, it supports bidirectional power conversion for grid-tied and off-grid operation.

Key Product Features

  • Modular independent PCS structure, single unit fault will not interrupt the whole system, system availability up to 98.6%.
  • Multi-branch separate DC input design, no direct parallel connection of battery clusters to avoid circulating current damage to batteries.
  • Integrated PCS and step-up transformer in one container, saving land space and greatly simplifying on-site installation and commissioning.
  • Strong environmental adaptability, stable operation in desert, high temperature, coastal salt fog and other harsh outdoor environments.
  • High protection grade: IP55 for the whole cabin, IP66 for internal PCS power modules.
  • Supports VSG, PQ, VF three operation modes, realizes seamless switch between grid-tied and off-grid working status.
  • Accurate switching control of source-grid-load, ideal for microgrid and backup power projects.
  • Built-in LVRT and HVRT functions, excellent grid-friendly performance to meet global grid access standards.
  • Complete multi-level safety protection, compatible with mainstream BMS & EMS via standard communication protocols.

Core Product Advantages

Ultra-high System Reliability: Adopts independent modular PCS layout. Individual module failure only affects its own branch without full-system shutdown, reaching 98.6% system availability and minimizing power station downtime losses.

Effective Battery Lifespan Protection: Multi-channel isolated DC input avoids direct parallel connection of battery clusters, completely eliminating circulating current risks, reducing cell heat generation and extending the service life of lithium battery packs.

Greatly Reduced On-site Construction Costs: PCS and step-up transformer are fully pre-integrated in a standard container cabin. No separate transformer room or power distribution building is required, cutting over 60% of field wiring, civil work and commissioning workload.

Wide Adaptability for Global Outdoor Projects: Wide temperature operating range from -40℃ to +60℃, together with IP55 cabinet & IP66 module dustproof and waterproof performance, supporting stable operation in deserts, high-temperature zones and coastal salt-fog areas.

Flexible Operation for Diverse Grid Demands: Equipped with VSG, PQ and VF control modes, supporting seamless grid-tied/off-grid switching. It covers multiple application demands including grid frequency regulation, peak-valley arbitrage and island standby power supply.

Full Grid Compatibility Worldwide: Built-in LVRT and HVRT functions with THDi less than 3% under rated power. It satisfies grid access standards for most countries and regions, applicable to both 50Hz and 60Hz power grids.

Universal & Expandable Communication Compatibility: Supports RS485, CAN and Ethernet ports, matching mainstream protocols such as Modbus RTU/TCP, IEC104 and IEC61850. It can seamlessly connect with third-party BMS and EMS platforms for remote monitoring and data management.

Complete Multi-layer Safety Protection Mechanism: Integrated overvoltage, overcurrent, short-circuit, insulation monitoring and overheating protection functions, with graded fault alarm and shutdown logic to avoid safety hazards for equipment and battery clusters.
