Product FAQs

What applications is a 1MWh containerized energy storage system suitable for?

This system is designed for commercial and industrial (C&I) applications, including peak shaving, load shifting, backup power, microgrids, data centers, manufacturing facilities, and off-grid or weak-grid locations such as mining sites and islands.

Can the system integrate with solar PV and diesel generators?

Yes. It supports PV + battery + diesel hybrid operation. The system can prioritize solar energy, store excess power, and automatically dispatch the diesel generator when solar output is insufficient or during grid outages.

How fast is the switching time during a power outage?

The system features a built-in Static Transfer Switch (STS) with a switching time of less than 20 milliseconds, ensuring uninterrupted power supply for critical loads and sensitive equipment.

Is the system pre-assembled and easy to install?

Yes. It is a fully integrated, factory-tested containerized solution with plug-and-play design. This significantly reduces on-site installation time, labor costs, and project complexity.

What safety features are included in the system?

The system includes liquid cooling, multi-level fire protection, and advanced battery cluster management with real-time monitoring and fault isolation to ensure high safety and long-term reliability.

How does the system help reduce energy costs?

It enables peak shaving and load shifting by storing energy during off-peak hours and discharging during peak demand. This reduces electricity bills and can also defer transformer upgrades.

About Battery Energy Storage System(BESS)

Commercial and Industrial Battery Energy Storage Systems (C&I BESS) are designed to help businesses manage energy more efficiently and maintain stable power supply. These systems store electricity and discharge it during peak demand or grid instability, providing fast, clean, and reliable energy support for daily operations.

Why Commercial & Industrial Energy Storage Matters

Battery energy storage enables peak shaving and load shifting, helping businesses reduce electricity costs and demand charges. It also delivers reliable backup power during outages, protecting critical equipment and minimizing downtime. When integrated with solar or other renewable sources, C&I BESS improves energy utilization and reduces dependence on diesel generators.

Due to higher power demand and system requirements, commercial and industrial energy storage is typically deployed in factories, logistics centers, EV charging hubs, commercial buildings, data centers, and solar-plus-storage projects where stable, scalable, and high-availability power is essential.
