Industry Challenge 01

DC Safety Challenge

The AC and DC coupling schemes for energy storage systems are complex. Ensuring consistency across millions of highly integrated battery cells is difficult, increasing the risk of DC faults.
Industry Challenge 02

Equipment Miniaturization Requirements

With the iterative advancement of battery cells and power device technologies, equipment power density increases. The miniaturized cabinet design imposes stricter requirements on the physical dimensions of switches.
Industry Challenge 03

Seamless Grid-Tied to Off-Grid Transition for Sensitive Loads

During the transition from grid-tied to off-grid operation in residential and commercial & industrial storage, slow switching speeds can cause excessive power loss duration for electronic devices and sensitive loads, leading to unexpected shutdowns.
