1500V String Inverters (320–350 kW)

Property Specification

Type: Ultra-High-Power 1500V Three-Phase Utility String Inverter (320 kW / 350 kW Rating)

Features: Engineered to maximize financial returns on large-scale solar assets, this high-capacity string inverter platform comes available in multi-tracker options of 12 MPPTs or 15 MPPTs. Designed with maximum string input current handling of 15A to 20A, it provides seamless compatibility with modern large-format bifacial solar PV modules (182mm and 210mm wafer designs). Integrated Anti-PID suppression and dynamic PID-recovery systems proactively counter and reverse Potential-Induced Degradation to sustain module output over time. Built with severe-duty weatherproofing.

Applications: Large-scale utility solar farms, high-voltage centralized PV power plants, ground-mounted commercial power generation assets, and extreme-climate solar installations requiring high power density, advanced module degradation recovery, and optimized LCOE.
