String Inverter, also known as On-grid or grid-tied inverter, is a type of inverter that generates power by connecting to the grid. It automatically stops working when the grid is disconnected to comply with anti-islanding requirements. SolaX offers both single-phase and three-phase string inverters, ranging from 600W to 8kW and 3kW to 150kW respectively, to cater to different power needs.
