Large Scale Energy Storage System

Characteristics & Advantages

What makes a Utility-Scale ESS the right investment for your project.

01

Solar Power, Clean Energy

Bulk clean electricity from utility-scale PV arrays fed into the grid.

02

Saved Cost

Peak shaving and arbitrage cut levelized cost of energy across the plant.

03

Scalable Capacity

Containerized BESS scales from 500 kWh to multiple MWh per site.

04

Cost-Effective & Reliable

Turnkey containers with PCS, EMS, HVAC and fire suppression for 20-year service.

How The System Works

Component flow from generation to storage to load / grid.

Frequently Asked Questions

For standard models our MOQ starts from 10–20 units; for fully customized OEM/ODM projects we support low-volume trial runs from 50 units so you can validate the market before mass production. Contact our sales team for a model-specific quotation.
All MECC products are built with Grade-A LiFePO4 cells and certified to ISO9001, CE, UL 1973, UN38.3, IEC 62619 and RoHS. Container and cabinet systems can be supplied with additional regional compliance on request.
Samples are usually ready within 7–15 working days. Bulk production lead time is 25–35 days depending on configuration and order volume. We keep common models in stock to support faster delivery for distributors.
We offer a 5–10 year product warranty and a cycle life of 6,000+ cycles at 80% DOD. Every system ships with remote monitoring, and our engineers provide commissioning guidance plus a spare-parts plan for the full service life.
Yes. Share your load profile, tariff, grid conditions and site layout, and our engineers return a capacity calculation, single-line diagram, 3D layout and full BOM quotation within 24 hours - free of charge.
We have shipped to 140+ countries across Europe, North America, Africa, the Middle East, Southeast Asia and Oceania, with full DG (dangerous goods) documentation, UN38.3 packing and experience in sea, air and rail freight.
