3MWH BESS

Increase the capacity of a single cabinet and dilute the cost: Through modular integration technology, the 3MWh energy storage system is integrated into 1-2 standard containers (compared to 3 1MWh containers), reducing the number of containers, floor space and supporting equipment (such as PCS, BMS main control unit), and reducing the initial investment cost by 15%-20%.

Larger capacity supports longer load regulation, releases more electricity during peak hours (such as the peak of air conditioning in summer), and further reduces the transformer demand electricity fee (can reduce 20%-30% of the basic electricity fee), especially suitable for high-load industrial and commercial users (such as large factories and data centers).

Adopt large-capacity lithium iron phosphate battery cells (single cell capacity ≥ 300Ah) + module-level liquid cooling design, the temperature difference between the battery cells is controlled within ±2℃ to avoid the risk of local overheating; PACK-level fire protection (perfluorohexanone precision injection) + container-level explosion venting + combustible gas monitoring, to achieve "battery cell-module-box" three-level linkage protection, the safety level reaches UL9540A certification standard.

Support longer off-grid power supply (such as full power discharge can last for 4-6 hours), can provide "power insurance" for key production lines in factories, hospital operating rooms, data center servers, etc., to avoid millions of economic losses caused by power outages.

When matched with large-scale distributed photovoltaics (such as power stations above 10MWp) or wind power, it can store more surplus green electricity and increase the self-consumption rate of renewable energy to 85%-95% (much higher than the 60%-70% of small-capacity systems), helping enterprises achieve the goal of "zero-carbon factory".

The 3MWh system has a large single-cabinet capacity (such as 1.5MW/3MWh configuration), which can directly match high-load scenarios such as large factories (annual electricity consumption of 50 million kWh+), commercial complexes (centralized power supply for multiple formats), and centralized energy storage stations in industrial parks, reducing the complexity of multi-cabinet parallel connection.
