This BESS helps businesses significantly reduce electricity costs by shifting energy use from peak tariff periods to off-peak hours. It also improves solar self-consumption, reduces grid dependence, and provides backup power for critical loads during outages.

With its modular structure, the system is easy to maintain and can be expanded for future energy needs. It is well suited for factories, commercial buildings, industrial parks, microgrids, and renewable energy projects.

Key Features

High Safety
Multi-level BMS protection, electrical isolation, and advanced thermal management ensure safe and stable operation.

High Efficiency
High-voltage design reduces system losses and improves overall energy conversion efficiency.

Long Service Life
0.5C system design reduces battery stress and extends cycle life, lowering the Levelized Cost of Storage (LCOS).

Smart Energy Management
Compatible with EMS platforms for intelligent scheduling, remote monitoring, and data analysis.

 

20ft

The Megarevo 500kW PCS enables seamless bidirectional power conversion, supporting both grid-connected and off-grid operation. It offers fast response to load fluctuations and provides grid support functions such as reactive power compensation and voltage regulation.

 

 

battery

The 1000kWh high-voltage lithium battery system uses safe and long-cycle LiFePO₄ cells. Its high-voltage design reduces current, improves system efficiency, and minimizes energy loss. An intelligent Battery Management System (BMS) continuously monitors voltage, current, temperature, and state of charge to ensure safe and stable operation.

 

system logic

This system adopts an AC-coupled architecture, where the battery energy storage system connects to the AC bus through a 500kW Megarevo bidirectional PCS, while photovoltaic (PV) generation (if present) is connected via separate grid-tied inverters. An intelligent Energy Management System (EMS) coordinates power flow between the grid, loads, PV system, and battery storage.
