Tsty Containerized Centralized Bess Step up Unit IP68 Oil Tank for Large Scale Energy Storage Project for Investor

Product Description

TSTY Centralized Energy Storage Converter and Step Up System – Large Scale Battery Storage Solution

The TSTY centralized energy storage converter and step up system is a highly integrated power conversion and boosting solution designed for utility scale battery energy storage systems (BESS). This system efficiently stores green energy from solar or wind power and, when needed, converts DC battery power into grid compliant AC via a power conversion system (PCS). The AC power is then stepped up by a three phase oil immersed step up transformer to medium voltage levels of 10kV or 35kV for stable transmission to the grid. The system is factory assembled in a containerized enclosure, combining the PCS, transformer, high voltage switchgear, low voltage distribution, and intelligent monitoring into one integrated unit. It effectively mitigates the intermittent and volatile nature of renewable energy generation, improving energy efficiency and grid stability.

Product Advantages

High Integration & Space Saving – Combines PCS, transformer, switchgear, and monitoring in one containerized unit, reducing footprint by up to 50% compared to traditional solutions.

Fast Deployment – Factory pre assembled and tested, on site work limited to pad preparation and cable connection – commissioning time reduced by approximately 50%.

Simple Maintenance – Unattended operation supported by remote monitoring; no dedicated personnel required on site.

High Safety – Oil immersed load switch with full range fuses; flame retardant transformer oil; optional automatic fire extinguishing devices.
Low Loss & High Efficiency – Amorphous alloy or high efficiency silicon steel core reduces no load losses by over 30%.

Strong Environmental Adaptability – Special shot blasting and anti corrosion treatment resists UV, salt spray, sandstorms, and extreme temperatures.

Applications

The TSTY centralized energy storage converter and step up system is widely deployed in the following scenarios:

Grid Scale Energy Storage – Utility owned BESS for frequency regulation, spinning reserve, voltage support, and peak shaving.
Renewable Power Plants – Solar and wind farms with integrated storage to smooth output fluctuations and improve grid compliance.
Commercial and Industrial Storage – Factories, data centers, and shopping malls for peak valley arbitrage and demand charge reduction.
Microgrids and Off Grid Systems – Islands, mining sites, and remote villages supporting solar storage diesel hybrid operation.
Emergency Backup – Critical facilities requiring instant backup power during grid outages.
