Case Study: BSL Battery HV Pack 10 & GoodWe ET-50kW hybrid inverter

Chicken Farm Case Study BSL Battery HV Pack 10 & GoodWe ET-50kW hybrid inverter

Picture this: A thriving chicken farm in South Africa housing thousands of birds suddenly faces a crisis. The power grid can not keep pace with demand, threatening precise climate control systems, automated feeding schedules, and critical ventilation. For this operation, power is not just a convenience; it is literally a matter of life and death for thousands of living creatures and the economic survival of the business.

This real-world scenario perfectly illustrates the energy challenge facing commercial and industrial (C&I) operations in Southern Africa. When traditional grid infrastructure fails to meet modern business demands, the consequences ripple through productivity, profitability, and operational continuity.

Real-World Success: The South African Chicken Farm Case Study

The Challenge

A large-scale poultry operation faced a critical infrastructure limitation: “Current demand is quite large, and the grid feed is relatively too small to meet the demands of having the equipment run efficiently,” explained Devin from GoodWe South Africa.

For this operation, inadequate grid infrastructure was not just an inconvenience; it threatened the precise environmental controls necessary for animal welfare and operational profitability.

The Solution

The installation featured four GoodWe ET-50 (50kW) inverters paralleled through the EZ Link 3000 controller, paired with the BSL HV Pack battery storage and generator backup. This hybrid configuration provided:

  • Immediate Power Security: UPS-level switching ensuring no interruption to critical systems
  • Scalable Infrastructure: Current setup expandable to 10 units using the SEC 3000 energy management controller
  • Operational Flexibility: Ability to meet varying demand patterns while maintaining efficiency

The Impact

The solution delivered “more flexibility regarding the hybrid solution on expansion, on storage size, and the demand that can be met”. Beyond keeping systems operational, it enabled precise environmental control, automated feeding, and critical ventilation for thousands of birds—directly impacting animal welfare and bottom-line profitability.

This case demonstrates how modern energy solutions transform operational challenges into competitive advantages through reliable, scalable, flexible power management.

The Strategic Shift Toward Renewable Energy

Modern C&I operations require more than just available electricity; they need power that is flexible, efficient, and reliable. From processing facilities to critical data centres and agricultural operations, energy interruptions lead directly to lost revenue and disrupted operations.

The BSL HV Pack Battery and the GoodWe ET-50 hybrid inverter are changing energy management at a poultry farm.

The BSL Battery HV Pack

At the heart of modern C&I energy solutions lies advanced modular battery technology, exemplified by the BSLBATT HV Pack. Far more than a typical backup battery, this system is a sophisticated, scalable storage solution designed for commercial and small-to-medium-sized industrial applications.

The BSL HV Pack 10, with a capacity of 7.776kWh per module, delivers dependable backup and energy storage to reduce reliance on the grid and safeguard critical operations. Its robust design ensures reliable performance during outages and peak demand periods, making it ideal for high-demand commercial environments

Key Technical Advantages:

  • Modular easy-snap lock design: Scale from 39 kWh to 400 kWh capacity
  • LFP Chemistry: Lithium iron phosphate cells providing exceptional thermal stability
  • Impressive Longevity: 6,000 cycles at 90% depth of discharge, translating to 15+ years operational life
  • Safety First: Integrated fire suppression system and UN 38.3 transportation certification
  • Smart Integration: Built-in Wi-Fi, Bluetooth, CAN BUS, and Modbus RTU connectivity

Why Modularity Changes Everything

The modular approach represents a fundamental shift in energy planning. Instead of overbuilding capacity or facing expensive infrastructure overhauls, businesses can start with what they need today and seamlessly expand as operations grow. Each 7.8 kWh module snaps into place without disruption, allowing systems to support up to five groups with 10 packs per group.

This flexibility proves invaluable for agricultural operations where seasonal demands fluctuate, manufacturing facilities planning expansion, or any business requiring adaptable power infrastructure without massive upfront capital investments.

Performance Specifications That Matter

Operating at voltages from 100V to 1,000V with continuous charge/discharge current of 135 amps, these systems handle significant power flows for demanding applications. The broad operational parameters ensure compatibility with diverse C&I requirements while maintaining reliability under heavy loads.

The GoodWe ET Series – Three Phase Hybrid Inverter

While batteries provide the foundation, hybrid inverters serve as the intelligent brain managing energy flow between solar panels, storage systems, and the grid. The GoodWe ET series (40kW and 50kW three-phase models) exemplify this sophisticated energy orchestration.

Advanced Features:

  • Dual-Mode Operation: Seamless on-grid and off-grid functionality
  • Parallel Connectivity: Scale inverter capacity by adding units
  • UPS-Level Switching: Millisecond transition to backup power with static transfer switch integration
  • 150% DC Input Oversizing: Maximise solar harvest even in suboptimal conditions
  • 98.1% Maximum Efficiency: Extract maximum value from every ray of sunlight

The UPS-Level Advantage

When paired with GoodWe’s static transfer switch (STS box), these inverters provide UPS-level switching capabilities—transitioning to backup power in milliseconds. For critical operations like data centres, hospitals, or sensitive manufacturing lines, this virtually eliminates power interruptions that could cause equipment damage or disrupt operations.

The system seamlessly integrates with existing diesel generators, optimising their use by recharging batteries efficiently instead of operating continuously at partial load. This hybrid approach optimises fuel consumption while ensuring long-term stability.

Maximum Solar Optimisation

With multiple Maximum Power Point Trackers (MPPTs), these inverters optimise input from different panel groups even when facing different directions or experiencing partial shading. Combined with 150% DC input oversizing capability, they supercharge solar production during peak conditions while maintaining strong performance throughout varying weather conditions.

Strategic Applications Across Industries

These advanced energy solutions serve diverse C&I applications:

  • Peak Shaving: Reduce demand charges by using stored energy during expensive peak periods
  • Backup Power: Maintain critical operations during grid outages
  • Demand Response: Participate in utility programs while maintaining operational flexibility
  • Solar Self-Consumption: Maximise renewable energy usage
  • Grid Independence: Operate in remote locations or areas with unreliable infrastructure

Industries benefiting include agribusiness, manufacturing, telecommunications, education, and any operation that requires reliable, efficient power management.

Take Control of Your Energy Future

The energy landscape is constantly changing, and businesses that proactively address power challenges position themselves for sustained success. Whether you’re a solar installer seeking advanced solutions for C&I clients or an agricultural operation planning energy infrastructure upgrades, the time for strategic energy planning is now.
