Product Description

Energy Storage System Container Hybrid Solar System Solar Battery Storage
Containerized ESS

20-ft and 40HQ liquid-cooled ESS container integrates PACK, EMS, BMS, HVAC, and fire safety system into one cabinet. Compared with air cooling, liquid cooling empowers the ESS product with higher power density and ensures the temperature difference between the cells within 3 ºC, which effectively extends battery service life and improves energy efficiency. The 20-ft liquid-cooled ESS container product can be applied to the power generation side, grid side, as well as C&I ESS scenarios that have strict requirements on power and capacity.

Frequently Asked Questions

QHow does DC coupling optimize the use of renewable energy?

It allows for captured solar energy to be stored directly with minimal losses. This ensures a greater portion of power is used on-site or dispatched to the grid efficiently.

QWhat role does the Power Conversion System (PCS) play?

The PCS is a high-power, bidirectional inverter that converts DC from solar and batteries to AC. it streamlines infrastructure by replacing separate solar and battery inverters.

QWhat are the advantages of DC-coupled systems?

Key advantages include higher overall system efficiency, a simplified layout with fewer components, reduced BOS costs, and seamless on/off-grid integration.

QWhy is DC coupling more efficient for large scale storage?

It avoids multiple DC-AC-DC conversion steps. Solar energy directly charges the batteries in DC form, which maximizes ROI by reducing energy losses.

QWhat is DC coupling in large scale solar battery storage?

It is a system architecture where solar panels and batteries connect on the same DC bus before conversion to AC by a single centralized inverter.

QWhat is the life cycle of the lithium batteries?

The system features high-quality LiFePO4 batteries with a cycle life of 8000 times and above, ensuring long-term reliability for industrial applications.
