Seplos Ultra Power 1000: Redefining Utility-Scale Microgrid Energy Storage for a Sustainable Future

As a leading professional provider of utility-scale battery storage solutions, Seplos has long been at the forefront of innovation, dedicated to delivering efficient, safe, and intelligent microgrid energy storage systems that empower communities, industries, and remote regions with reliable and sustainable power. With a deep understanding of the evolving energy landscape and the growing demand for resilient, low-carbon energy infrastructure, Seplos proudly introduces the Seplos Ultra Power 1000—a revolutionary, fully integrated 1.3 MWh Battery Energy Storage System (BESS) housed in a standard 20-foot container. Designed for scalability, durability, and ease of deployment, this turnkey solution represents the next evolution in modular energy storage technology.

The Seplos Ultra Power 1000 is engineered to meet the complex energy needs of modern microgrids. It integrates high-capacity LiFePO4 (lithium iron phosphate) batteries, a robust 500kW Power Conversion System (PCS), photovoltaic (PV) input support up to 600kW, and an advanced Energy Management System (EMS)—all seamlessly unified within a single, compact, and transportable unit. This all-in-one design eliminates the complexity of traditional multi-component systems, reducing integration challenges, minimizing installation time, and ensuring optimal system performance from day one.

At the heart of the Ultra Power 1000 are high-energy-density 314Ah battery cells, renowned for their superior safety profile, thermal stability, and extended cycle life. LiFePO4 chemistry is inherently safer than other lithium-ion variants, with a lower risk of thermal runaway, making it ideal for mission-critical and remote applications. These cells are meticulously managed by an intelligent, multi-layered Battery Management System (BMS) that monitors voltage, current, temperature, and state of charge (SOC) at the cell, module, and system levels. The BMS ensures balanced charging and discharging, prevents overloading, and significantly extends battery lifespan—often exceeding 6,000 cycles at 90% depth of discharge (DoD), translating into over 10 years of reliable service.

Safety is non-negotiable in large-scale energy storage, and the Ultra Power 1000 sets a new benchmark. The system features dual fire protection mechanisms, combining passive thermal insulation with active fire suppression. Integrated smoke, temperature, and gas detectors continuously monitor the internal environment, while a targeted suppression system—using environmentally friendly extinguishing agents—can be automatically deployed in the rare event of a thermal incident. This comprehensive safety architecture ensures compliance with international standards such as UL 9540, IEC 62619, and NFPA 855, providing peace of mind for operators and stakeholders.

One of the standout capabilities of the Ultra Power 1000 is its seamless transition between on-grid and off-grid operation. With an ultra-fast 20ms switching time, the system ensures uninterrupted power supply during grid outages or fluctuations—critical for industrial operations, healthcare facilities, and remote communities. Additionally, the system is equipped with black start capability, enabling it to restore power independently without relying on an external grid connection. This feature is particularly vital in disaster recovery scenarios or in regions with unstable or non-existent grid infrastructure.

The advanced Energy Management System (EMS) is the brain of the Ultra Power 1000. It enables intelligent energy optimization through features such as solar priority utilization, peak shaving, load shifting, and multi-energy coordination. By prioritizing renewable energy input—especially from solar—the system maximizes self-consumption, reduces reliance on diesel generators or grid power, and lowers energy costs. During peak demand periods, the system automatically discharges stored energy to avoid high electricity tariffs, delivering measurable savings. The EMS also supports remote monitoring, diagnostics, and over-the-air (OTA) updates, allowing operators to manage the system from anywhere in the world via a secure cloud platform.

Designed for versatility, the Seplos Ultra Power 1000 is ideal for a wide range of applications, including industrial parks, remote islands, weak-grid regions, and off-grid communities. In industrial settings, it stabilizes power supply, reduces peak demand charges, and supports sustainability goals. In remote areas, it serves as the cornerstone of a resilient microgrid, integrating with solar, wind, or diesel generators to provide a consistent and cost-effective power source. For weak-grid regions, it enhances grid stability, prevents blackouts, and enables the integration of renewable energy at scale.

Beyond performance and reliability, the Ultra Power 1000 is built for the real world. Its standard 20-ft containerized design ensures easy transportation, rapid deployment, and resistance to harsh environmental conditions. The unit is engineered to withstand extreme temperatures, humidity, and dust, making it suitable for deployment across diverse geographies—from tropical islands to arid deserts.

In an era defined by climate change and energy insecurity, the Seplos Ultra Power 1000 is more than a product—it’s a promise. A promise of stable power, economic resilience, and environmental stewardship. By enabling a cleaner, more reliable energy future, Seplos is not just delivering technology—we are powering progress.
