Turnkey Solution DC Power Connector ESS Equipment | Perfect for EV Supercharging Stations

Executive Overview: The DC Power Connector Advantage

Designed for the most demanding commercial and industrial (C&I) applications, the DC Power Connector is not merely a battery cabinet—it is a fully integrated, turnkey energy storage solution. Engineered to bridge the gap between photovoltaic generation, EV supercharging infrastructure, and grid stability, this system delivers unmatched cycle life and a superior Levelized Cost of Energy (LCOE). With a 10-Year Performance Warranty and global Local O&M support, your project pipeline is secured from factory acceptance to sea freight and on-site commissioning.

Built for Extreme Cycles & Thermal Safety

The DC Power Connector integrates Tier-1 Grade A LFP (LiFePO4) cells, guaranteeing over 8,000 cycles at 80% Depth of Discharge (DoD). Unlike standard storage units, this cabinet leverages a smart liquid cooling architecture that maintains cell温差 within ±1.5°C, drastically reducing capacity degradation over 15 years. The active balancing Battery Management System (BMS) operates at the cell level, ensuring every kilowatt-hour is available for peak shaving or backup events. For procurement managers, this translates directly to maximized ROI and minimized total cost of ownership.

Product Overview & Safety Architecture

Safety is non-negotiable in C&I environments. The DC Power Connector features a multi-layered fire suppression system (aerosol + gas-based) coupled with IP65-rated weatherproof housing. The unit includes an integrated Power Conversion System (PCS) supporting seamless on-grid and off-grid transitions, making it ideal for micro-grids and industrial parks. High-voltage disconnects and arc-fault circuit interrupters are standard, complying with global shipping safety protocols (UN38.3, MSDS).

Target C&I Facilities & EV Supercharging Layouts

EV Supercharging Stations

Pair the DC Power Connector directly with 150kW-350kW DC fast chargers. The system buffers grid demand, prevents demand charges, and enables ultra-fast charging even in areas with weak grid infrastructure. This turnkey PV-Storage-Charging solution includes integrated EMS software for smart load dispatch.

Industrial Parks & Manufacturing Hubs

Utilize the unit for heavy peak shaving, reducing monthly demand charges by up to 40%. The liquid-cooled design operates reliably in ambient temperatures from -20°C to 55°C, suitable for outdoor containerized yards or indoor electrical rooms.

Micro-grid & Remote Operations

With seamless black-start capability and a rapid <20ms islanding detection, the DC Power Connector ensures 100% uptime for critical processes, replacing diesel generators with clean, silent power.

Global Supply Assurance & Turnkey Delivery

As a leading source manufacturer with 15 years of OEM/ODM experience, we offer direct wholesale pricing with lead times as short as 30 days for standard units. Global sea freight logistics are managed in-house, including door-to-door delivery, customs clearance, and local O&M onboarding. Every unit is factory-tested (FAT) with a digital commissioning report. Backed by 10-year performance warranty and 24/7 remote technical support, your project financing and long-term asset management are secure.

Frequently Asked Questions (B2B Procurement)

What is the actual usable capacity and cycle life of the DC Power Connector?

The base model offers 215kWh usable energy (100% DoD allowed with LFP chemistry). At 0.5C charge/discharge, the system retains >70% of nominal capacity after 8,000 cycles, verified by third-party UL testing.

How does the liquid cooling system reduce my OpEx compared to traditional air cooling?

Liquid cooling reduces auxiliary power consumption by up to 30%, extends cell cycle life by 15%, and allows the cabinet to operate continuously in high-temperature environments without derating, directly improving project IRR.

What global certifications does this unit hold for shipping and utility interconnection?

The DC Power Connector is fully certified to UL 9540A (thermal runaway), UL 1973, IEC 62619, CE, UN38.3 for transport, and complies with IEEE 1547 grid interconnection standards. Certificates are provided per shipment batch.

Can I integrate this with existing solar PV and diesel generators?

Yes. The EMS controller supports Modbus TCP/IP, CAN bus, and dry contact interfaces. Our turnkey solution includes remote commissioning to synchronize with any major PV inverter brand (Huawei, SMA, Sungrow) or existing genset controllers.

What is the typical lead time for a 5MW project using multiple DC Power Connector units?

For project volumes of 20+ units, lead time is 45-60 days after down payment. We provide a detailed Gantt chart covering production, factory acceptance testing (FAT), sea shipping (e.g., 30 days to Europe/US), and local logistics. Local O&M partners are pre-assigned for commissioning.
