Communication Box for PV Systems

SPC01 is a power control box designed for power limitation and zero-export control in compliance with local grid codes. Working with KSTAR three-phase PV grid-tied inverters (3–125 kW) via RS-485, its built-in smart meter collects real-time grid-side power data, ensuring precise export regulation for residential, commercial, and industrial solar systems.
