General
Q: What does Energy Storage Industries (ESI) do? A: ESI supplies advanced battery energy storage equipment that supports Australia’s renewable energy transition. We provide utility-scale, grid-scale, and commercial-and-industrial energy storage systems that deliver safe, stable, and intelligent power management.
Q: Where are ESI systems designed and supported? A: The equipment supplied by ESI is designed and manufactured by leading global partners and tested extensively to meet international performance, safety, and regulatory standards. Installation, commissioning, and support are delivered locally by Australian partners, ensuring compliance with local standards and reliable on-the-ground service.
Q: What types of storage systems does ESI provide? A: ESI supplies grid-forming, grid-scale Battery Energy Storage Systems (BESS) and commercial and industrial Energy Storage Systems (ESS). Our BESS range spans from approximately 5 MWh to multi-GWh installations, while ESS units range from around 108 kWh to 4 MWh. These systems are designed and tested to meet stringent international and Australian standards, providing safe, reliable, and flexible solutions for large-scale renewable and grid-connected applications.
Safety
Q: What makes ESI systems safer than other battery technologies? A: The battery systems we supply are engineered with a “safety first” design philosophy. Safety is not just about meeting compliance — it’s designed in at every level of the product. The platform incorporates multi-layer mechanical, electrical, and thermal protection that goes beyond standard requirements, using an “attack–defense” approach to anticipate faults and contain them before they become hazards. Independent testing with TÜV has defined three safety levels — basic, plus, and prime — with “prime safety” representing an enhanced level of protection designed to prevent fire spread and protect people and assets even under extreme fault conditions. This delivers one of the highest available safety certifications for battery energy storage.
Q: How is safety managed during operation? A: The systems are built with intelligent monitoring that continuously tracks key operating conditions — including temperature, electrical performance, and enclosure environment — across cells, packs, and enclosure. This monitoring provides the data required for real-time oversight of system health and safety from cell to grid. In practice, this enables early detection, controlled response, and safe shutdown behaviour to protect equipment, personnel, and the wider site.
Reliability
Q: How do ESI systems perform in Australia’s harsh conditions? A: ESI systems are designed, tested, and proven for Australian environments — from coastal Safety
Q: What makes ESI’s products different from other systems? A: The equipment we supply undergoes one of the most comprehensive testing and validation processes in the industry. Every component is selected and qualified through extensive laboratory and environmental testing — including high-altitude, extreme-temperature, high-humidity, and coastal-exposure assessments — to confirm long-term durability and performance stability. This level of verification ensures each unit performs reliably in real-world conditions across Australia’s diverse climates. While many systems are designed for wide operating ranges, few are validated through such extensive, all-environment testing programs.
Grid Forming Technology
Q: What is grid-forming and why is it important? A: Grid-forming technology allows a battery energy storage system to create its own stable voltage and frequency reference — effectively behaving like a generator. This enables storage systems to form and stabilise “islanded” networks or operate independently of the main grid when required.
Q: How does ESI implement grid-forming capability? A: ESI-supplied equipment includes intelligent power conversion systems and control architecture designed for advanced grid-forming operation. These systems allow seamless transition between grid-connected and islanded modes, automatically managing voltage, frequency, and phase stability for reliable operation under dynamic grid conditions.
Q: What are the benefits of grid-forming systems? A: Grid-forming capability enhances resilience, fault ride-through, and renewable integration — providing stable power quality even in weak or remote grids. It also enables renewable energy installations to operate more efficiently when coupled with storage, reducing curtailment (“spilled” energy) and improving the financial performance of renewable projects.
Q: Where is grid-forming most valuable? A: Grid-forming is particularly beneficial in regional and remote communities, hybrid renewable systems, and microgrids, as well as in areas where the network is weak. It is also becoming increasingly important across the broader grid for system stability and support as renewable penetration grows.
Smart String ESS — Battery Energy Storage System
Q: What battery technology does ESI supply? A: ESI supplies advanced lithium-iron-phosphate (LFP)–based energy storage systems selected for their proven safety, thermal stability, and long cycle life.
Q: Are ESI systems scalable? A: Yes. The grid-forming, grid-scale BESS is modular, scaling from approximately 5 MWh to multi-GWh capacity. The commercial and industrial ESS is also modular, scaling from around 108 kWh to 4 MWh, providing flexibility across a wide range of applications and project sizes.
Q: How safe are ESI’s battery systems? A: Safety is engineered throughout the equipment — from individual cells to battery packs, battery systems, and all the way to grid connection. Each layer includes mechanical, electrical, and thermal protection, together with advanced fire-suppression and intelligent thermal-management features to ensure safe, stable operation.
Q: Can ESI systems be used off-grid? A: Yes. ESI-supplied batteries can operate across all grid scenarios — including grid-connected, off-grid, and hybrid configurations — supporting solar, wind, or diesel generation as required.
Installation, Maintenance & Support
Q: How long does installation take? A: Installation and commissioning timeframes depend on project scope and site requirements. The modular design of the supplied equipment supports efficient deployment, allowing systems to be assembled and energised within shorter timelines than traditional BESS configurations.
Q: What maintenance is required? A: Routine inspections and software monitoring help maintain optimal performance. Intelligent diagnostics and automated analytics minimise on-site service frequency and support long-term operational reliability.
Q: What warranties are provided? A: ESI offers comprehensive product and performance warranties. Coverage terms vary by equipment type and configuration — refer to the relevant data sheet or contact our technical team for details.
Q: How do I get technical support? A: For technical assistance, please contact support@energystorageindustries.com or use the enquiry form on our website.
Australian Capability
Q: Does ESI provide local technical support? A: Yes. As the local equipment supplier, ESI provides technical support covering installation supervision, commissioning oversight, and warranty coordination. We work directly with certified installation and maintenance partners who perform on-site service under ESI’s supervision. Our role is to train and accredit those partners, ensuring they operate to the required technical and safety standards, while maintaining full compliance with product warranty conditions and performance guarantees.
