As battery energy storage systems (BESS) continue becoming critical for renewable energy integration, peak demand management, and industrial decarbonization, energy storage platforms are evolving toward higher-capacity and software-integrated architectures capable of supporting utility-scale and commercial applications. PowerX has developed the Mega Power series, a large-scale battery storage platform designed for grid-scale, renewable energy, and commercial & industrial energy storage applications.
The Mega Power product lineup currently includes the Mega Power 2700A and the Mega Power 2500 systems. The Mega Power 2700A provides a nominal capacity of 2,742 kWh and rated capacity of 2,468 kWh, while the Mega Power 2500 is designed with a nominal capacity of 2,507 kWh and rated capacity of 2,257 kWh.
From a technical standpoint, the systems are based on lithium iron phosphate (LFP) battery technology and are engineered around high-voltage operating architectures. The Mega Power 2700A operates within an 850–1,241 V range and utilizes air cooling, whereas the Mega Power 2500 operates within a 1,040–1,477 V range and incorporates liquid cooling for thermal management.
The battery systems are designed for applications ranging from high-voltage and extra-high-voltage grid battery farms to renewable energy integration projects and industrial energy management installations. According to the company, the systems support integrated deployment of battery storage systems, PCS, transformers, switchgear, EMS, and output curtailment units as part of comprehensive battery farm solutions.
A major aspect of the platform is its vertically integrated architecture, where hardware, battery management systems, controllers, cloud infrastructure, and energy management software are developed in-house. The company’s PowerOS platform functions as an IoT-based energy management system that supports monitoring, control, security, maintenance, and integration with AI-based optimization applications.
The systems are additionally engineered with a strong focus on cybersecurity and infrastructure reliability. According to PowerX, the hardware design complies with standards including EF 263.7 and U.S. cybersecurity policy NERC CIP, while remote-control systems are designed in accordance with ERAB and IoT security guidelines. The company also states that its information security management systems are certified under ISMS/ISO 27001.
For commercial and industrial applications, the battery storage systems are designed to support peak-shift energy management and renewable energy utilization. The company states that installations can reduce electricity costs by up to 38% through charging and discharging control. In comparison, renewable energy utilization can increase by up to 40% when integrated with photovoltaic systems. Both systems also comply with multiple international and Japanese standards, including IEC62619, IEC62933, JIS8715-2, JIS C4441, UL9540A, and UL1973, and align with JC-STAR Level 1 requirements.
By combining high-capacity LFP battery systems, integrated energy management software, cybersecurity-focused infrastructure, and utility-scale deployment capabilities, PowerX’s Mega Power platform is designed to support grid stabilization, renewable energy integration, and advanced industrial energy management applications.
