It stably operates under harsh outdoor temperatures ranging from -30℃ to 55℃, and has passed ISO, IEC, CE international certifications.

Core Product Highlights

Aviation-Grade 3D Comprehensive Safety System

Three-layer safety protection at cell, module and cabin levels. Adopts perfluoro-ketone fire suppression + thermal runaway early warning, liquid cooling balanced temperature control to avoid heat accumulation and thermal spread risks.
Ultra-High Return on Investment, 3-5 Years Payback Period

92.5% charge-discharge efficiency and 100% depth of discharge maximize revenue from peak-valley electricity price difference. LCOS is reduced by 40% vs traditional ESS solutions, with extremely low O&M cost.
Extra Long Service Life

≥10,000 charge-discharge cycles for LFP cells, 15-year system design life, cutting equipment replacement amortization cost throughout full lifecycle.
Cloud-Based Intelligent & User-Friendly O&M

Independent cloud platform supports remote monitoring, automatic fault alarm and intelligent cell balancing. Real-time data access via PC & mobile terminals, greatly reducing on-site maintenance labor.
High Efficiency & Strong Environmental Adaptability

Liquid cooling system ensures uniform temperature distribution inside the cabin; 100% DOD without power waste; wide operating temperature range eliminates extra heating/cooling renovation for high/low temperature regions.
Modular Expandable Design

Single unit rated energy: 1860kWh; multiple cabins can be paralleled to reach 4MWh large-scale storage. DC cabin and AC PCS cabin can be supplied separately to match different site installation conditions.

Application Scenarios：

Industrial & Commercial User Side: Peak-valley electricity arbitrage, demand charge reduction, on-site PV self-consumption, emergency backup power for factories & parks;
Renewable Generation Side: Matching PV/wind power stations, smoothing power output, boosting renewable energy absorption rate;
Grid Side: Grid frequency regulation, voltage support, peak shaving & valley filling, deferring grid expansion, off-grid microgrid operation.

What are the rated capacity and power of this ESS? Is capacity expansion supported?

Model ESS1-935/1860-0.7-L(DC plus AC) features a rated energy of 1860kWh and rated AC power of 935kW. Based on the CNESS CUBE Mega 1500V platform, it supports modular capacity expansion from 0.7MWh to 4MWh, fully meeting the demands of large and medium-sized industrial and commercial energy storage projects.

What application scenarios is the system suitable for? Can it be matched with PV and wind power systems?

It covers three core application scenarios: user side, grid side and power generation side. It supports industrial & commercial peak-valley arbitrage, demand charge management, emergency power backup, on-site PV self-consumption, PV/wind power output smoothing, grid frequency/voltage regulation and peak shaving, which is ideal for solar-storage and wind-solar-storage integrated projects.

What safety protection designs does the product adopt? How about its safety performance?

It adopts an aviation-grade three-dimensional safety system with energy-storage dedicated LFP cells. Equipped with dual fire protection of perfluoro fire extinguishing agent and active thermal runaway early warning, plus full-range liquid cooling temperature control system, it effectively suppresses heat accumulation and thermal spread. Three-layer safety protection at cell, module and cabin levels eliminates potential risks and ensures ultra-high operational safety.

What is the system charge-discharge efficiency? What is the typical payback period?

The comprehensive system charge-discharge efficiency is ≥92.5%, leading the industry. With high efficiency and 100% DOD, it maximizes peak-valley arbitrage revenue. The LCOS is reduced by 40% compared with traditional ESS solutions with extremely low O&M costs, and the payback period of standard industrial and commercial projects is only 3-5 years.

Can the system reduce corporate electricity costs? What are the core cost-saving methods?

It can significantly cut industrial and commercial electricity costs through core methods including peak-valley electricity price arbitrage, demand charge management to reduce basic electricity fees, on-site PV self-consumption to reduce grid power purchase, peak load shaving, and replacing part of backup diesel generators to reduce energy consumption and O&M expenses.
