System ComponentsLithium Battery ClusterThe main components of system consist of a battery module formed by safe, high-efficiency, long-life lithium iron phosphate cells connected in series, and a battery cluster formed by multiple modules connected in series.

Battery Management SystemThe core component of the svstem effectivelv protects the battery from over-charging, over-discharging, over-current, etc., and at the same time manages the equalization of the battery cells to guarantee the safe, reliable and efficient operation of the whole system.

Monitoring SystemSystem operation data monitoring, operation strategy management, historical data logging, system status logging, etc.

PCS Power Conversion SystemBidirectional AC/DC converter can realize the bidirectional conversion of DC to AC and AC to DC, which can either convert AC to DC for charging the battery, or convert DC to AC to supply power to the load or feed back to the grid.

Air Conditioning SystemThe battery compartment integrates 1200W industrial air conditioner to meet the smooth operation of the svstem in different environments and prolong the service life of the system.

1P54IP54 design for the whole system.
