350kW String Inverter

Pain Points in the Application Scenario

The breaking capacity of the conventional DC disconnector switch is insufficient for the multi-parallel technology of 210 modules. DC arc faults affect system safety.

Value of the Solution

The independent original design solves the switch current capacity bottleneck of 210 large-module multi-parallel systems. The product design features a significant breaking capacity buffer, capable of adapting to harsh environments with minimal derating.
