Description
SAJ 50kW On-Grid Inverter
The SAJ 50kW On-Grid Inverter is a high-capacity, three-phase grid-tied solar inverter designed for large commercial rooftops, small industrial plants, and community-scale solar power systems. Built with advanced technology and smart functionality, it ensures high conversion efficiency, system safety, and real-time performance monitoring.
This inverter is equipped with multiple MPPT trackers (typically 4), allowing flexible array design and superior energy yield, even under shading or mixed orientation conditions. Its wide MPPT voltage range enhances compatibility with various solar module types and string configurations, making system design more flexible.
With a maximum efficiency of up to 98.8%, the SAJ 50kW inverter minimizes power losses and boosts ROI. Integrated Wi-Fi or optional GPRS supports remote monitoring through SAJ’s eSolar portal or mobile app, giving installers and users complete insight into system performance.
Engineered for durability, it comes in a rugged IP65-rated enclosure suitable for both indoor and outdoor environments. Its intelligent cooling system ensures safe operation in hot conditions, while built-in protections—such as anti-islanding, overvoltage, and ground fault protection—ensure long-term reliability and safety. The inverter meets international grid codes, making it suitable for deployment in multiple regions.
