ChargeStack 1000 —  a 1 MW to 3.5 MW megawatt charging system (MCS)  is designed to redefine scalability, profitability, and grid integration across electrified transport landscape of Europe.

ChargeStack 1000 — 1+X Design, Grow As You Go

The ChargeStack 1000 represents a major leap forward in scalability, uptime, and return on investment. Each design reflects Sungrow's deep understanding of operators' needs — balancing high performance with long-term profitability and seamless service.

• 1+X, Scalable Growth

With a flexible power cabinet design, operators can scale effortlessly from 1 MW to 3.5 MW. The system supports MCS (1500A) and CCS2: 500 A oil-cooled (boost 800A) standards, enabling one solution to serve diverse fleet applications. Its decoupled architecture allows MCS or V2G upgrades without hardware replacement, reducing upgrade costs by up to 70%.

• 1+X, Profitable Growth

Built for cost efficiency, the ChargeStack 1000 enables a 30-minute "Power Nap Charge"  at 1500A, delivering 600 kWh (SOC 10–95%). Its in-house developed SiC modules achieve 97% efficiency, minimizing energy loss, while Full-Matrix Power Distribution improves charging throughput by 33% and ensures 98.5% uptime — even under diverse climate conditions in Europe.

• 1+X, Grid-Friendly Growth

The ChargeStack 1000 is an intelligent one-stop beyond charging solution integrating solar, storage, and smart charging management. It optimizes energy flow and grid interaction while enabling operators to gain up to 60% higher profitability through demand response, peak-valley arbitrage, and VPP participation. One-stop commissioning boosts construction efficiency by 50%, and Sungrow's global service platform ensures remote monitoring, rapid response, and full lifecycle reliability — turning every station into a smart, value-generating asset.

• 1+X, Experience-Driven Growth

Sungrow delivers a superior charging experience through seamless OCPP 2.0.1 integration, E-Truck Wake-Up function design, dynamic reactive power control, ergonomic cable design, smart lighting, and plug-and-charge capability. Its Cloud & Web-interface Monitoring ensures one-stop system configuration, diagnostics, and data security. With deployment achievable within just 2–4 weeks, and backed by over 520 global service outlets and 24/7 after-sales support, Sungrow ensures reliable operation and excellent service.

Strategic Partnerships Accelerate E-Mobility in Europe

During the summit, Sungrow announced strategic partnerships with leading charging operators, system integrators, energy solution providers and logistics companies across Europe to accelerate the region's e-mobility transition.

With the ChargeStack 1000 and new partnerships in place, Sungrow continues to expand its e-mobility footprint in Europe — empowering operators and partners to accelerate the transition toward zero-emission transport through scalable, intelligent, and profitable charging solutions.
