Kstar 125kW PV inverter
Designed for commercial, industrial, and utility-scale solar projects, the Kstar 125kW Three-Phase On-Grid PV Inverter delivers high power density and reliable grid-tied performance. By combining advanced 8-MPPT tracking with cost-saving PLC communication technology, this high-capacity inverter optimizes solar harvesting while significantly lowering system installation and balance-of-system (BOS) expenses.
Key Features & Operational Advantages:
-
125 kW Power Class: High-power output designed for high-capacity industrial plants and utility projects, reducing the total number of inverters required per solar farm.
-
8 Independent MPPT Trackers: Features 8 MPPTs with a wide 200–1000V operating voltage range, enabling precise power tracking across complex rooftop layouts, varying orientations, and shaded arrays.
-
PLC Communication (Power Line Communication): Transmits monitoring data directly over existing AC power lines—eliminating dedicated RS485 signal cabling. This drastically slashes wiring costs, shortens site commissioning, and simplifies long-term O&M.
-
Unified Smart Connectivity: Flexible integration via RS485, PLC, WiFi, and Ethernet interfaces, combined with clear LED indicators and Bluetooth App access for real-time fleet diagnostics and remote management.
-
Industrial Durability & Safety: Engineered to handle utility-scale grid dynamics, providing high system uptime and simplified maintenance across large PV power plants.
