Our sodium-ion energy storage system boasts comprehensive strengths covering safety, reliability, installation convenience and intelligent energy management. Adopting premium A+ grade sodium-ion cells, it features multi-layer fuse safeguards plus built-in aerosol fire suppression on both pack and rack tiers for utmost safety. Rigorous design and testing deliver steady performance across diverse scenarios, with overcharge, overdischarge and overtemperature protection eliminating potential hazards. Boasting high integration and modular construction, the unit enables effortless transportation, on-site setup and adjustable capacity layouts. Its advanced EMS supports peak shaving, demand reduction, onsite power self-use and electricity price arbitrage, bringing tangible economic benefits for users.

This sodium ion battery portable power station adopts a single 230Ah sodium-ion cell design, featuring exceptional low-temperature performance with 85%–92% capacity retention at -20°C and stable discharge at -30°C, removing the need for internal heating films to cut costs. It boasts superior safety over lithium iron phosphate batteries with strong resistance to puncture, extrusion and impact, no lithium dendrite risks, and excellent tolerance to overcharge and over discharge. Abundant sodium resources insulate it from lithium price volatility for favorable long-term kWh costs. The single-cell structure eliminates series voltage imbalance, simplifying BMS circuitry, lowering failure rates and easing production and after-sales service. With centralized, uniform heat dissipation, the product delivers markedly lower overheating risks compared to multi-cell battery packs
