EVOLISUN EVO-Na-130KW/260KWh Sodium-ion Outdoor Integrated Energy Storage Cabinet

1. Product Overview

1.1 Product Introduction

The EVO-Na-130KW/260KWh is a fully self-developed outdoor sodium-ion battery energy storage system (Na⁺-ion BESS) independently designed by EVOLISUN. The all-in-one cabinet integrates sodium-ion battery modules, intelligent BMS, bidirectional PCS, independent temperature control & cooling system, fire suppression unit and remote cloud monitoring module. Adopting an outdoor cabinet structure with IP54 protection grade, the system can be put into operation quickly after on-site wiring without extra power distribution room construction.

Different from conventional lithium iron phosphate energy storage equipment, this unit adopts sodium-ion cells as core energy storage medium. It features ultra-wide operating temperature range, intrinsic high safety without thermal runaway, sufficient raw material supply and outstanding cycle life. Perfectly suitable for extreme hot & cold climates in the Middle East, Africa and BRICS countries, it serves a wide range of scenarios including commercial & industrial PV-storage on/off-grid system, microgrid, off-grid rural power supply, industrial backup power and hybrid PV-diesel energy projects.

1.3 Core Competitive Advantages

1. Ultra-wide Temperature Adaptability
Operates stably from -40℃ to +60℃. No capacity attenuation under high temperature, and normal charge-discharge performance at sub-zero temperature, solving common pain points of lithium storage systems such as capacity loss in Middle East heat and shutdown in cold regions like Russia & South Africa.

2. Intrinsic Superior Safety
Sodium-ion material avoids thermal runaway risk; no fire or explosion risks under puncture, extrusion or overheating conditions. Equipped with cabinet-level aerosol fire suppression and multi-stage protection against overvoltage, overcurrent and short circuit.

3. Stable & Controllable Cost
Sodium mineral resources are abundant worldwide, free from sharp price fluctuations of lithium ore, ensuring stable long-term supply chain and cost advantages for bulk procurement.

4. Plug-and-play Integrated Design
All battery, power conversion, cooling, monitoring and fire control components are pre-installed and pre-wired in factory. On-site commissioning can be finished within 2 hours after connecting PV, diesel generator or load cables.

5. Full-lifecycle Intelligent Management
Supported by self-developed EVOLISUN Cloud Platform, enabling real-time remote data monitoring, fault early warning, parameter adjustment and operation report export via PC or mobile APP.

6. Ultra-long Cycle Durability
Cells support over 6,000 deep charge-discharge cycles (80% DoD), ideal for commercial peak-valley arbitrage and daily frequent cycling off-grid applications.

7. Weatherproof Outdoor Cabinet
IP54 dustproof & waterproof enclosure with anti-rust, sun-proof and rain-proof design, allowing direct ground installation outdoors without dedicated shelter.

2. Main Technical Specifications

3. Cabinet Internal Structure

The cabinet is divided into two physically isolated zones: battery compartment and power control compartment to reduce heat conduction risk.

3.1 Battery Compartment

• Independent voltage & temperature sampling for each module; BMS real-time cell balancing to prevent overcharge & overdischarge.

• Separated heat dissipation air channels with thermal insulation gaps between modules.

• Two-stage fuse and short-circuit protection switches for each string.

3.2 Lower Power & Control Compartment

• Bidirectional PCS power conversion unit

• Main controller & 7-inch local touch screen

• Remote communication module & cloud data transmitter

• Main input/output circuit breakers and lightning protection devices

• Fire control host and cooling fan drive system

3.3 Exterior Cabinet Configuration

• Double front access doors with safety lock latches for convenient maintenance

• Integrated waterproof canopy on cabinet top

• Emergency stop button & 3-color status indicator (Running / Fault / Standby) on front panel

• Large ventilation louvers with removable dust filter screens on side panels

4. Typical Application Scenarios

1. Commercial PV-Storage System for the Middle East
Stable operation under high ambient temperature in Saudi Arabia, Iraq, UAE and other regions. Realize self-consumption and peak shaving to ease power grid shortage and high electricity cost.

2. Off-grid Microgrid for BRICS Nations
Power supply for remote mines and villages without utility grid coverage in Russia, Brazil and South Africa, matching PV + sodium storage + diesel hybrid solution.

3. Industrial Critical Load Backup Power
Uninterrupted emergency power for factory automation equipment, server rooms and medical facilities; wide temperature range fits open-air industrial plants.

4. Large-scale Cross-border Energy Storage Projects
Suitable for bulk procurement by EPC contractors; standardized size supports containerized sea transportation with spot goods available in overseas warehouses.

5. Island & Nomadic Area Independent Power Supply
Long-duration stable energy storage for areas without mains power, adapting to extreme wild temperature environments.

5. Intelligent Monitoring & Cloud Platform Functions

5.1 Local Touch Screen Operation

7-inch touch display mounted on cabinet front, supporting real-time viewing of power, SOC, voltage, temperature and fault codes; local configuration of charge & discharge strategies.

5.2 Remote EVOLISUN Cloud Management

• Visual real-time operation data of the whole system

• Automatic fault alert with notification pushed to APP & SMS

• Remote modification of charge/discharge logic and grid protection parameters

5.3 Third-party Data Interface

Supports standard Modbus protocol for connection to external energy management platforms and SCADA host systems.

6. Six-level Integrated Safety Protection System

1. Cell Intrinsic Safety: No lithium plating risk; no fire or explosion under puncture & extrusion.

2. Module-level Protection: Real-time cut-off for single string overvoltage, undervoltage, overtemperature and overcurrent.

3. Compartment Isolation: Thermal barrier separates battery zone and power control zone.

4. System Electrical Protection: Main circuit breaker, lightning protection, leakage and short-circuit dual protection.

5. Active Temperature Control: Extra forced cooling triggered by overheating; power derating or automatic shutdown under extreme high temperature.

6. Automatic Fire Suppression: Smoke & temperature dual detection; aerosol fire extinguishing and high-voltage circuit cut-off activated once fire hazard detected.
