成果简介	NOVELTY - The system has a solar panel string arranged in an array, where the string generates a direct current (DC) output. A string combiner box is received and consolidated the DC output from the string into a single DC output. An inverter control card is disposed in a solar inverter to detect a fault condition in a photovoltaic solar unit and to transmit a tripping signal to a DC molded case circuit breaker (MCCB) to isolate the SCB from the inverter. The DC MCCB is provided with an integrated shunt trip coil. USE - System for automatic isolation of a string combiner from a solar inverter of a photovoltaic solar system for residential, commercial and industrial applications. ADVANTAGE - The system enables efficient fault management and reduces the risk of damage to inverters and other equipment, which is essential for maintaining continuous power supply for agricultural needs. The automated isolation and fault detection system enables for reliable operation with minimal human intervention. The system enhances safety for residential users and ensures continuous power availability for unaffected sections by providing automatic isolation in case of faults. By isolating faulty SCBs within the microgrid, the system maintains power flow to other parts of the network, ensuring stability and reliability across the grid. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method for isolating at least one String Combiner Box SCB from a solar inverter. DESCRIPTION OF DRAWING(S) - The drawing shows a block diagram of a system for isolating string combiner box from solar inverter.
