With several sets of our liquid-cooled all-in-one BESS successfully commissioned in Europe recently, Ewicharge is helping C&I facilities and fast charging hubs enhance energy flexibility and grid resilience. How can commercial energy storage systems deliver tangible benefits to businesses? It’s more than storing energy—it’s about unlocking revenue and avoiding infrastructure bottlenecks. Today’s C&I storage buyers are looking beyond just batteries—they demand faster deployment, smarter management, higher ROI as well as turnkey integration with existing infrastructure.
Ewicharge all-in-one BESS is typically available in 218kWh, 241kWh and 350kWh capacities tailored for commercial and industrial applications mainly. The 350kWh BESS, with 1P/1C charge/discharge capability, addresses these evolving demands with a fully liquid-cooled, all-in-one design for most on-grid and off-grid energy use cases.

This solution provides convenient Plug & Play socket option for fast deployment at construction or mining sites, where grid power is either unavailable or unreliable. It also supports optional STS connection to ensure uninterrupted power supply for off-grid applications.
Application Scenarios
1. Remote Area Backup Power
For construction or mining areas lacking in reliable power supply, power interruptions can lead to costly downtime and project delays. This system can serve as reliable backup power for critical construction loads or mining vehicles. With fully liquid-cooled design, it provides high protection, high reliability and longevity in most extreme outdoor operation conditions.
2. HPC Support without Grid Limits
As electric vehicle adoption accelerates, the demand for High-Power Charging (HPC)—especially in urban charging hubs or along highways—is outpacing grid infrastructure upgrades. With 1C discharge capacity, this 350kWh system acts as a power buffer to support HPC in areas with grid limitations, reducing grid stress.
3. Microgrid Application
In remote areas or underserved islands, the system can operate as the foundation for localized microgrids, requiring only a minimal of 33kW AC grid connection. It’s also a reliable and sustainable alternative to traditional power solutions, such as diesel generators.
4. Peak Shaving for C&I Businesses
For businesses facing demand charges, the system allows to charge the battery when electricity prices are the lowest, and to discharge it during peak hours. By peak-valley arbitrage, it makes a powerful asset for ROI-focused energy users.
5. Distributed Solar Storage
This system enables hassle-free integration of max 80kW MPPT solar power for storage, enabling businesses and communities to maximize solar utilization while ensuring grid stability and energy resilience.
Product Highlights
- Fully liquid cooling: Adopts liquid-cooled battery packs and isolated liquid-cooled PCS, achieving superior heat dissipation and protection in all outdoor environments.
