500KW 6MWH rechargeable battery systems

500KW 6MWH rechargeable battery systems

Each battery ESS container is equipped with 8 clusters of battery strings, each cluster of battery strings is equipped with a 20kW DC/DC converter, and 8 DC/DCs are connected to the DC bus in an aggregated manner.Most DC/DC converters can only work one-way, when to make the energy flow two-way, we can use two-way DC/DC converter because it can keep the DC voltage polarity at both ends of the converter unchanged. Bidirectional DC/DC converter has the advantages of bidirectional energy transmission, less number of power electronic devices, small size, high efficiency and low cost.

Our BESS has these features:

1.Superior uniformity and EV grade safety lithium battery cells;
2.System capacity can be formed from 500KWh to Max.4MWh 
in one container,multiple containers can be combined into large-scaled BESS.
3.Advanced energy management technology,easy installation ,high round-trip efficiency,customized modular .
4.Reliable system safety design and remote real-time monitoring.
5.Fastest delivery time 6-8weeks.

As a Lithium battery storage power station, it applies to below scenarios:
Commercial,residential or industrial energy backup.

Integrated all-in-one energy storage solutions for Grid Stabilization.

Island or electricity shortage area.
Power and Grid System Load Leveling.
Renewable energy (Solar and Wind) firming.
Remote Off-Grid Power Generation.
