Description
The Canadian Solar High-Efficiency Grid-Tied Inverter is engineered for advanced solar energy systems, offering powerful performance, safety, and long-term reliability. With a multiplex MPPT design, it delivers optimal energy harvesting even in complex installation conditions. Its 16A input current supports the latest high-power PV modules, while the integrated DC switches. This inverter includes smart string monitoring, optional anti-PID and AFCI protection, and intelligent fan cooling for stable operation in all environments. Built with IP66 protection, it’s designed to perform in harsh outdoor conditions and provides utility-interactive controls like active power derating, reactive power control, and over-frequency derating for grid stability.
