Power Save 100

Power Save modules are versatile bidirectional power electronic inverters designed for both grid-connected and off-grid battery storage applications. These inverters prioritize a balance of high efficiency and cost-effectiveness. Available in 100 kW units, Power Save is modular, allowing multiple units to be interconnected in parallel for scalable MW-level storage systems. They feature a wide DC input voltage range, accommodating various battery modules. Power Save supports multiple operational modes such as peak shaving, load shifting, and ancillary grid services like frequency support. Developed with over 20 years of industrial and academic expertise, Power Save incorporates state-of-the-art research and design.

In Off-Grid (Island) mode, these inverters can operate in parallel to supply power directly to local loads. Each Power Save unit includes two internal converters (DC/DC and DC/AC) with corresponding filters, ensuring complete bidirectional functionality.

Energy Management System

The Energy Management System (EMS) serves as the overarching supervisory control that manages the operation of battery storage inverters, directing when to charge or discharge the battery and at what power levels. It is tailored to achieve various objectives such as peak shaving, load shifting, cost reduction by minimizing grid energy consumption, maximizing utilization of onsite renewable energy (e.g., solar, wind), or optimizing revenue from grid power sales. The EMS can also balance multiple conflicting objectives or adhere to restrictions imposed by network operators to limit grid exports.

The complexity of the EMS corresponds to the complexity of the installed assets. For instance, in a scenario where a battery energy storage system operates under two different grid tariffs (cheaper at night, more expensive during the day), managing it without onsite renewables would be straightforward: charge the battery overnight and discharge during the day to save costs. However, with solar panels onsite, the EMS must anticipate available solar energy during the day to optimize battery charging, considering the battery may already be charged from night-time grid power. This complexity increases with factors like dynamic tariffs, varying loads, and diverse renewable sources, necessitating an intelligent EMS capable of managing these intricacies.

Our EMS incorporates artificial intelligence to forecast future generation and load, drawing on our advanced research in this field. Our team engages with clients to tailor EMS solutions to specific needs, ensuring optimal performance. Additionally, our EMS features a cloud-based portal system for comprehensive monitoring and control.

Static Transfer Switch

A Static Transfer Switch (STS) is a crucial component in electrical power distribution systems, ensuring continuous power supply to vital loads. Its primary role involves seamlessly switching between multiple power sources, such as mains electricity and backup generators, or between independent power grids. This transition occurs instantaneously, guaranteeing uninterrupted power flow and uninterrupted operation of essential equipment and systems.

Built with solid-state power electronics such as thyristors or insulated-gate bipolar transistors (IGBTs), an STS enables rapid and reliable switching between sources. These components, supported by monitoring and control circuits, detect power quality issues and swiftly transfer the load to the most reliable available source.

Static Transfer Switches are extensively used across diverse industries, particularly in data centers, hospitals, telecommunication facilities, and critical infrastructure where uninterrupted power is critical. In environments where even a brief power interruption could result in significant financial losses or endanger lives, STS units provide essential reliability.
