What Is a PCS?

A Power Conversion System (PCS) is a key component of a Battery Energy Storage System.

It controls the flow of electrical energy between the battery and the AC electrical network.

During charging:

AC Grid / Solar → PCS → Battery

During discharge:

Battery → PCS → AC Loads / Grid

This bidirectional conversion allows the BESS to participate in applications such as peak shaving, load shifting, backup power and renewable-energy integration.

Commercial & Industrial Applications

The Golen LEG-250K/500K-TT-B is suitable for:

• Manufacturing plants
• Industrial facilities
• Large factories
• Hotels and resorts
• Hospitals
• Flower farms
• Commercial buildings
• Shopping centres
• Warehouses
• Cold-storage facilities
• Large agricultural operations
• Data and technology facilities
• Commercial microgrids

Energy Storage Applications

Peak Shaving

Discharge stored battery energy during periods of high demand to help reduce peak electrical demand and optimize energy costs.

Load Shifting

Store energy when appropriate and discharge it during periods of higher demand or when grid electricity is less economically attractive.

Solar + BESS

Integrate large-scale solar PV with battery storage to increase solar self-consumption and improve energy availability.

Backup Power

The PCS can form part of a properly engineered backup-power system supporting critical loads during grid interruptions.

Generator Hybridization

Combine battery storage with diesel generation and solar PV to improve generator utilization and energy management.

Microgrids

The PCS can be incorporated into commercial and industrial microgrid architectures combining multiple energy sources and controllable loads.

Typical System Architecture

A typical large-scale C&I system may include:

Solar PV → PV Inverter → AC Bus

HV Battery → Golen PCS → AC Bus → Commercial / Industrial Loads

with:

Grid + Generator + EMS + Protection + Monitoring

The final architecture depends on the site’s load profile, battery configuration, grid connection, operating strategy and applicable electrical standards.

Why Choose a 250kW / 500kW PCS?

Large commercial and industrial facilities can have significant instantaneous power requirements.

A high-power PCS provides a scalable interface between large battery banks and the facility’s electrical network.

The Golen LEG-250K/500K-TT-B can therefore serve as a building block for BESS projects ranging from large commercial installations to industrial energy-storage systems.

For larger projects, multiple PCS units may be considered where the manufacturer’s approved system architecture supports parallel operation.

Powerstack C&I BESS Integration

Powerstack Africa Energy can integrate the Golen PCS into a complete commercial or industrial energy-storage solution.

A typical project can include:

Energy Audit

Analyse electricity consumption, operating hours and demand profile.

Load Analysis

Identify peak demand, critical loads and energy-storage requirements.

BESS Sizing

Determine the appropriate battery capacity and PCS power rating.

System Design

Develop the electrical architecture, protection, controls and energy-management strategy.

Equipment Supply

Supply the PCS, batteries, EMS, protection equipment and associated system components.

Installation & Commissioning

Complete installation, testing, configuration and commissioning.

Monitoring & Maintenance

Provide ongoing technical support and system performance monitoring.

Suitable Battery Configurations

The Golen LEG-250K/500K-TT-B should be paired with an appropriately matched high-voltage battery system.

Depending on the project, Powerstack can engineer configurations using:

• 100kWh+ commercial BESS
• 200kWh+ BESS
• 500kWh BESS
• 1MWh BESS
• Multi-MWh containerized BESS

Battery voltage, current, BMS communication and PCS compatibility must be confirmed during system design.

Technical Specifications

Final technical specifications such as DC voltage range, maximum DC current, AC voltage, AC frequency, efficiency, overload capability, IP rating, cooling system, communication interfaces, dimensions and operating temperature should be confirmed from the latest manufacturer datasheet.
