Centralized 1+X Modular Inverter 3MW Centralized Inverter 350kW String Inverter Substation(800/1140V)DC Combiner Box (24 in 1)

DC Combiner Box (24 in 1)

Pain Points in the Application Scenario

The 1500V DC circuit breaker with a 4P configuration is excessively wide. The circuit breaker is unsafe for single-pole interruption in the event of DC grounding faults.

Value of the Solution

The product saves 40% of the combiner box’s horizontal space, significantly reducing the sheet metal costs of the enclosure. It eliminates the safety risks of single-pole disconnection under grounding fault conditions, improving the continuous fault-free operation capability of power stations.
